WARNING
stop control elements (MSC1 and MSC2). NEVER install suppressors directly across the output contacts of
the ES-FL-2A safety relay. It is possible for suppressors to fail as a short circuit. If installed directly across
the output contacts of the safety relay, a short-circuited suppressor will create an unsafe condition which
could result in serious injury or death.
WARNING
NEVER wire an intermediate device (for example, a programmable logic controller - PLC), other than a safety relay,
between ES-FL-2A safety relay outputs and the master stop control element it switches. To do so sacrifices the
control reliability of the control-to-machine interface, and creates an unsafe condition which could result in serious
injury or death. Whenever a safety relay is added as an intermediate switching device, a normally-closed forced-
