Installation
The RSG2000 Family chassis ground connection, shown in Figure 18, uses a #6-
32 screw. It is recommended to terminate the ground connection in a #6 ring lug,
and to use a torque setting not exceeding 15 in·lbs (1.7 Nm).

Terminal
Number
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.
NOTE: Surge Ground must be disconnected from Chassis
Ground during HIPOT (dielectric strength) testing.
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.
5 PS2 Live / +
PS2 Live / + is connected to the positive (+) terminal if the power
source is DC or to the (Live) terminal if the power source is AC.
6 PS2 Surge Ground
PS2 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.
NOTE: Surge Ground must be disconnected from Chassis
Ground during HIPOT (dielectric strength) testing.
7 PS2 Neutral / -
PS2 Neutral / - is connected to the negative (-) terminal if the
power source is DC or to the (Neutral) terminal if the power
source is AC.
8 Relay NO Contact Normally open, failsafe relay contact.
9 Relay Common Failsafe relay common contact.
10 Relay NC Contact Normally closed, failsafe relay contact.
