5.2.4 Connecting binary output signals
Check that the proper power supply and LECM modules are mounted on the DIN rail.
The DOM4 module has four signaling outputs with a common return for a pair of two
outputs. The default contact status during auxiliary shutdown and startup phase is
“Opened”. Once a valid configuration is accepted, the contacts operate based on the
output activation commands received via communication services.
The rated voltage for binary output connection is 250 V AC or 250 V DC. The binary
output contact operation time is 5...7 ms.
1. Fasten the output connector through the upper and lower screw terminals.
2. Connect wires to the DO and COM signals.
