Description Note
1 PWR1
Line/DC+
PWR1 Line/DC+ is connected to the
positive (+) terminal if the power source is
DC, or to the Line terminal if the power
source is AC.
2 PWR1
Neutral/DC-
PWR1 Neutral/DC-
is connected to the
negative (-) terminal if the power source is
DC, or to the Neutral terminal if the power
source is AC.
3
Surge Ground
Surge Ground is connected to the Ground
via a jumper on the terminal block. It
is used
as the ground conductor for all surge and
transient suppression circuitry.
NOTE: You must disconnect the Surge
Ground from the Ground during HIPOT
(dielectric strength) testing.
4 Ground Ground should be connected to the ground
terminal for AC power source 1.
