When voltage is removed from the relay coil (terminals 2 and 7) , the spring will
automatically return the relay contacts to the normal (un-powered) position, and
the LED indicator will turn off.
Installation
The Relay base can be mounted directly to a flat surface, or onto a standard
TS35 DIN rail. Follow local codes for installation of the relay and wiring. For
class 2 circuits, no enclosure is required. For all other circuits, the relay should
be mounted in an approved enclosure.
Wiring connections are made at the base terminals and are checked with the
relay unplugged.
Relay pulls straight out of base. Base can
be pre-wired and wiring can be tested
before plugging in relay. Relay can be
replaced without disturbing the wiring.
