Always disconnect power from the Safety Module and all power from the machine being controlled before
making any connections or replacing any component. Electrical installation and wiring must be made by
qualified personnel and must comply with the NEC (National Electrical Code), ANSI NFPA79 or IEC 60204-1, and
all applicable local standards and codes.
If arc suppressors are used, they MUST be installed as shown across the actuator coil of the Master Stop
Control Elements (MSC1 to MSC3). 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.
NEVER wire an intermediate device(s) (e.g., PLC, PES, PC), between the Safety Module outputs and the
master stop control element (MSCE) it switches in such a manner that in the event of a failure there is the
loss of the safety stop command, OR in such a manner that the safety function can be suspended,
overridden, or defeated, unless accomplished with the same or greater degree of safety. Whenever
forced-guided, mechanically linked relays are added as intermediate switching devices, a normally closed
forced-guided monitor contact from each relay must be added to the series feedback loop between Safety Module
terminals S31 and S32.
