Although this hookup shows model IM-T-9A, the hookup for model
IM-T-11A is identical.

WARNING: Use of Arc Suppressors
If arc suppressors are used, they MUST be installed as shown across the coils of the Machine Primary
Control Elements (MPCEs). NEVER install suppressors directly across the output contacts of the
Safety Module. It is possible for suppressors to fail as a short circuit. If installed directly across the
output contacts of the Safety Module, a short-circuited suppressor will create an unsafe condition
which could result in serious injury or death.

WARNING: Wiring of Arc Suppressors
If arc suppressors are used, they MUST be installed as shown across the actuator coil of the stop
control elements (MSCs or MPCEs). NEVER install suppressors directly across the output contacts
of the Safety Device or Module. It is possible for suppressors to fail as a short circuit. If installed directly
across the output contacts, a short-circuited suppressor will create an unsafe condition which could
result in serious injury or death.
