SE400 SERIES
By connecting the ground terminal by drain wire to earth ground the switch and chassis can
be ground.
The following section details the wiring of the relay output. The terminal block on the series is
wired and then installed onto the terminal receptor located on the series.
Figure 25: Terminal Receptor: Relay Contact
The terminal receptor includes a total of six pins: two for PWR1, two for PWR2 and two for a
fault circuit.
There are two power inputs for normal and redundant power configurations. The power input
2 is used for wiring a redundant power configuration. See the following for terminal block con-
nector views.

Note!
Before applying power to the grounded switch, it is advisable to use a volt meter
to ensure there is no voltage difference between the power supply’s negative out-
put terminal and the grounding point on the switch.

Caution!
Do not disconnect modules or cabling unless the power is first switched off.
The device only supports the voltage outlined in the type plate. Do not use any
other power components except those specifically designated for the switch
device.
Warning!
Power down and disconnect the power cord before servicing or wiring the switch.
