Figure 2.2. Power Supply Inputs
The RS900G HI power supply inputs are connected as follows:
1.
+/L should be connected to AC (Hot)
2.
-/N should be connected to AC (Neutral)
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 RS900G unit.
4.
Chassis Ground should be connected to the AC Ground terminal
1.
Equipment must be installed according to the applicable country wiring codes.
2.
Surge Ground MUST be disconnected from the Chassis Ground during HIPOT
(dielectric strength) testing.
3.
All line-to-ground transient energy is shunted to the Surge Ground terminal. In
cases where users require the inputs to be isolated from ground, remove the
ground braid between Surge and Chassis Ground. Note that all line-to-ground
transient protection circuitry will be disabled.
