Fig. 2.2.1 RS1600 Family Power Supply Inputs
The RS1600 family supports dual redundant power supplies – "Power Supply 1" and "Power
Supply 2" (see Fig. 2.2.1). Each power supply as a set of identical inputs that perform the following:
1. +/H is connected to the positive (+) terminal if the power source is DC or to the (Hot)
terminal if the power source is AC.
2. -/N 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 is connected to the Chassis Ground via a braided cable or other
appropriate grounding wire. Surge Ground is used as the ground conductor for all surge
and transient suppression circuitry internal to the RS1600. NOTE: Surge Ground must be
disconnected from Chassis Ground during HIPOT (dielectric strength) testing.
4. Chassis Ground is connected to the Safety Ground terminal for AC inputs or the
equipment ground bus for DC inputs.
Sections 2.2.1 to 2.2.5 describe connections for single, dual and mixed AC and DC power supply
inputs.
