Festo FEC Compact Brief Description page 28

For loads such as forward/reverse motor contactors, which
could be dangerous if switched on at the same time, there
should be both safety interlocks external to the IPC FEC
and programmed interlocks. This will prevent such loads
being activated simultaneously.
Please note
For emergency stop functions, the output loads should
be switched off by a switch external to the IPC FEC Com-
pact. This switch should isolate the on-load voltage
from the output terminals.
If you connect an emergency stop circuit, please make
sure that you follow the wiring and safety regulations
applicable in your country.
When using inductive loads take necessary precautions to
eliminate voltage trends.
Connecting a surge suppresser in parallel to an inductive
load reduces the electrical interference that is generated.
Caution
The operating voltage of the IPC FEC Compact is pro-
tected against polarity reversal. You should neverthe-
less check the polarity before using the module for the
first time.
