Connecting smart control module signals

Smart control module supports different switchgear application types such as
managing two-position or three-position switches or managing circuit breaker trip
commands or generic four binary inputs and four fast power outputs.
Check that the proper power supply and LECM modules are mounted on the DIN rail.
SCM8H/SCM8L modules have two sets of connectors. X1 is used for the binary
inputs and X2 for the solid state outputs. X1 connectors accept four binary input
connections with two isolated pairs of inputs per connection. X2 connectors have four
outputs with a common return for a pair of two outputs.
The voltage range for SCM8H binary input connection is 110...250 V DC (±20%).
The threshold is 78 V DC.
The voltage range for SCM8L binary input connection is 24...60 V DC (±20%). The
threshold is 13 V DC.
The operation time of the high-speed output contact is <200 µs.
1. Fasten the input and output connectors through the upper and lower screw
terminals.
2. Connect wires to the signals according to the used application.
The functionality of the four digital inputs is equal to the standard input board
DIM8. Each application type has different wiring requirements and a specific
connection diagram.
Check that the polarity of the solid state power outputs is correct.
Check the direction of motor rotation/moving switch, if applicable,
and ensure the right polarity of the high-speed outputs.
