Danger
|
|---|
|
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Never connect the 24 VAC supply output terminals 4 and 5 to any other power supply output, regardless of polarity. Failure to follow these instructions will result in death or serious injury. |
Recommended screw tightening torque: 0.56 to 0.79 Nm (5 to 7 lbf.in)
The 30 screw terminals are used as follows:
Two screw terminals for the power input
One screw terminal for protective earth ground
Two screw terminals for the 24 VAC output terminals 4 and 5
Six screw terminals for the four solid-state relay (SSR) outputs
Four screw terminals for the three relay outputs
Three screw terminals for the high power relay output
12 screw terminals for the eight universal inputs/outputs of type Ub
