Power Input Wiring Description
Refer to the following section for detailed power input wiring descriptions.
Terminal
Number
Description Note
1 PWR1 Line/ DC + PWR1 Line / DC + is connected to the positive (+) terminal if the power
source is DC and 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 and to the Neutral terminal if the power source is AC.
3 PWR1 Surge Ground PWR1 Surge Ground is connected to the Chassis Ground terminal via a
jumper on the terminal block. Surge Ground is used as the ground
conductor for all surge and transient suppression circuitry. NOTE: Surge
Ground must be disconnected from Chassis Ground during HIPOT
(dielectric strength) testing.
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.
5 NC No function
6 NC No function
7 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.
8 PWR2 Surge Ground PWR2 Surge Ground is connected to the Chassis Ground terminal via a
jumper on the terminal block. Surge Ground is used as the ground
conductor for all surge and transient suppression circuitry. NOTE: Surge
Ground must be disconnected from Chassis Ground during HIPOT
(dielectric strength) testing.
9 PWR2 Line/ DC + PWR2 Line / DC + is connected to the positive (+) terminal if the power
source is DC and to the Line terminal if the power source is AC.
10 PWR2 Neutral / DC - PWR2 Neutral / DC - is connected to the negative (-) terminal if the
power
source is DC and to the Neutral terminal if the power source is AC.
For AC Power Input
1. PWR1 Line/ DC + should be connected to AC (Line).
2. PWR1 Neutral / DC -should be connected to AC (Neutral).
