AS-P Server Screw Terminals

There are pluggable screw terminals at the top of an AS-P server.

The AS-P server comes in different models. The AS-P and AS-P-S models have three screw terminal blocks (with 4, 3, and 5 poles) whereas the AS-P-NL and AS-P-NLS models have two screw terminal blocks (with 4 and 3 poles).

Recommended screw tightening torque: 0.56 Nm (5 lbf.in)

The screw terminals 1 to 7, intended for RS-485 communication, act as connectors to the AS-P server and are easily inserted/removed without disrupting the network. Doing so may help in isolating possible RS-485 communication problems.
