How to
Wiring a Screw Terminal on RP-C
You wire the screw terminals on the RP-C to connect I/O devices and power. Always use the recommended wires (or wires with larger cross-sectional area).
The RP-C can be installed on a DIN rail or other flat surface inside a cabinet. In general, the device is recommended to be installed in a cabinet, unless local regulations allow an exception.
Rules and regulations
RP-C models with built-in wireless chip must be professionally installed to comply with the following rules and regulations:
Part 15 of the Federal Communications Commission (FCC) rules

The RP-C and its antenna(s) must be installed to provide a separation distance of at least 20 cm (8 in.) from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. Information on recommended RF exposure limits can be obtained from Health Canada's website, www.canada.ca/en/health-canada .
Installation orientation restrictions
The restrictions on installing the device in various orientations differ between the different RP-C controller models ( For more information, see RP-C Models .). In this regard, the RP-C models can be divided in the following categories:
RP-C 24 V models with “-F” in the product name:
RP-C-12A-F-24V, RP-C-12B-F-24V, RP-C-12C-F-24V, and RP-C-16B-F-24V
RP-C 24 V models with “-M” in the product name:
RP-C-12A-M-24V, RP-C-12B-M-24V, and RP-C-16A-M-24V
RP-C 230 V models: RP-C-16A-F-230V and RP-C-16B-F-230V
RP-C 230 V model: RP-C-16C-F-230V
Under normal operating conditions of 0 to 50 °C (32 to 122 °F), the RP-C 24 V controller models RP-C-12A-F-24V, RP-C-12B-F-24V, RP-C-12C-F-24V, and RP-C-16B-F-24V can be installed in the following orientations:
Horizontally (on a DIN rail going from left to right), with the device label text in the upright position reading left to right. See “a” in the following figure.
Vertically (on a DIN rail going from top to bottom), which means that the device is rotated +90 degrees or -90 degrees from the horizontal position. See “b” and “c” in the following figure.
Face down from a ceiling. See “d” in the following figure.
Face up on a horizontal surface. See “f” in the following figure.
The only installation orientation that is not supported for the RP-C 24 V controller models is when the device is rotated 180 degrees from the horizontal position, that is, with device label text up and down. See “e” in the following figure. In the up and down position, the controller's thermal specifications may be exceeded, which can damage the controller.
When the RP-C 24 V controller models are used for rooftop applications, -40 to +60 °C (-40 to +140 °F), the device should be installed horizontally, with the device label text in the upright position reading left to right. See “a” in the following figure. Any other installation orientation (“b”, “c”, “d”, “e”, and “f” in the figure) may exceed the controller's thermal specifications, which can damage the controller.
Under normal operating conditions of 0 to 50 °C (32 to 122 °F), the RP-C 24 V controller models RP-C-12A-M-24V, RP-C-12B-M-24V, and RP-C-16A-M-24V can be installed in the following orientations:
Horizontally (on a DIN rail going from left to right), with the device label text in the upright position reading left to right. See “a” in the following figure.
Vertically (on a DIN rail going from top to bottom), which means that the device is rotated +90 degrees or -90 degrees from the horizontal position. See “b” and “c” in the following figure.
Face down from a ceiling. See “d” in the following figure.
Up and down, which means that the device is rotated 180 degrees from the horizontal position and with the device label text up and down. See “e” in the following figure.
Face up on a horizontal surface. See “f” in the following figure.
Under normal operating conditions of 0 to 50 °C (32 to 122 °F), the RP-C 230 V controller models RP-C-16A-F-230V and RP-C-16B-F-230V can be installed in the following orientations:
Horizontally (on a DIN rail going from left to right), with the device label text in the upright position reading left to right. See “a” in the following figure.
Vertically (on a DIN rail going from top to bottom), which means that the device is rotated +90 degrees or -90 degrees from the horizontal position. See “b” and “c” in the following figure.
Installing the RP-C 230 V controller models rotated 180 degrees from the horizontal position is not supported. See “e” in the following figure. Installing the RP-C 230 V controller models face down from a ceiling (“d” in the figure) or face up on a horizontal surface (“f” in the figure) is only supported in the operating temperature range 0 to 40 °C (32 to 104 °F), but not in the temperature range 0 to 50 °C (32 to 122 °F). Installing the controller in an orientation that is not supported may cause the controller's thermal specifications to be exceeded, which can damage the controller.
Under normal operating conditions of 0 to 50 °C (32 to 122 °F), the RP-C 230 V controller model RP-C-16C-F-230V can be installed in the following orientations:
Horizontally (on a DIN rail going from left to right), with the device label text in the upright position reading left to right. See “a” in the following figure.
Vertically (on a DIN rail going from top to bottom), which means that the device is rotated +90 degrees or -90 degrees from the horizontal position. See “b” and “c” in the following figure.
Face down from a ceiling. See “d” in the following figure.
Up and down, which means that the device is rotated 180 degrees from the horizontal position and with the device label text up and down. See “e” in the following figure.
Face up on a horizontal surface. See “f” in the following figure.
Installation on a DIN rail
A DIN rail is a common and convenient technique for installing the RP-C controller along with other associated control and monitoring devices. The most efficient ventilation is achieved with the wall-mounted DIN rail oriented horizontally and with adequate space provided between the RP-C rail and adjacent rails or other devices.
The RP-C controller is typically installed horizontally (on a DIN rail going from left to right), with the device label text in the upright position reading left to right.
To help prevent the device from sliding down or sideways on the DIN rail, install an end clip for DIN 35 (part number SXWDINEND10001) tightly against the bottom or rightmost device on the rail. The end clip is easily removed if you bend the snap lock open with a screwdriver.
Installation in a cabinet
All RP-C controller models, except RP-C-16C-F-230V, are recommended to be installed in a cabinet, unless local regulations allow an exception.
The device should be installed within an enclosure such as a control cabinet for isolation to exposed live parts.
When installing RP-C controllers in a cabinet, it is recommended to provide ample space between the DIN rails and controllers for sufficient ventilation.
Screw terminals or connectors
All RP-C controller models, except RP-C-16C-F-230V, have fixed screw terminals. For more information, see RP-C Screw Terminals .
The RP-C-16C-F-230V controller model has PCB mounted connectors. For more information, see RP-C-16C-F-230V Pluggable Connectors .
Anchor points for cable ties
All RP-C controller models, except RP-C-16C-F-230V, have four anchor points that can be used to fasten cable ties or other accessories for bundling wires.
Optional covers
All RP-C controller models, except RP-C-16C-F-230V, can be equipped with optional covers to reduce access to the screw terminals and wires if desired. Covers are not available for RP-C-16C-F-230V as its design with pluggable connectors instead of screw terminals reduces access to the wiring.

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Disconnect the power supply and other high voltage equipment before wiring. Failure to follow these instructions will result in death or serious injury. |
Disconnect the power supply and other high voltage equipment connected to the controller.
Loosen the screw of the terminal.
Strip approximately 7 mm (0.3 inch) of the insulation from the end of each wire.
Insert the end of the wire fully into its intended terminal. Ensure that no bare wire strands extend from the terminal.
Tighten the screw using a small flat-blade screwdriver. Ensure that the screw is fully tightened. Use the following recommended screw tightening torque: 0.56 to 0.79 Nm (5 to 7 lbf.in).
Use appropriate cable strain relief methods, especially for wires that carry 30 VAC or 42.4 VDC or above, to help prevent any load applied to the cable from being transferred to conductor terminations.
You can use the anchor points on the controller enclosure and cable ties to fasten and fix the cables.
