compression plate allowing either bare wire connections or crimped terminal lugs. We
recommend the use of #6 size ring lugs to ensure secure, reliable connections under
severe shock or vibration. Both terminal blocks have a safety cover which must be
removed via two Phillips screws before connecting any wires. The safety cover must be
re-attached after wiring to ensure personnel safety. Refer to Table 3 and Table 4 below
for a description of each terminal as well as sections 2.2.1 through 2.2.3 for wiring
examples.
Terminal #
Description
Usage
1
PS1 Live / +
PS1 Live / + is connected to the positive (+) terminal
if the power source is DC or to the (Live) terminal if
the power source is AC.
2
PS1 Surge
Ground
PS1 Surge Ground is connected to the Chassis
Ground via a jumper on the terminal block. Surge
Ground is used as the ground conductor for all surge
and transient suppression circuitry.
3
PS1 Neutral / -
PS1 Neutral / - is connected to the negative (-)
terminal if the power source is DC or to the (Neutral)
terminal if the power source is AC.
4
Chassis Ground
Chassis Ground is connected to the Safety Ground
terminal for AC inputs or the equipment ground bus
for DC inputs. Chassis ground connects to both power
supply surge grounds via a removable jumper.
