2.2 Power Supply Wiring and Grounding
Fig. 2.2.1 RS500 Power Supply Inputs
The power supply input is connected as follows:
1.
+
= DC (+) is connected to the positive (+) terminal if the power source is DC or to the
(Hot) terminal if the power source is AC.
2.
-
= 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
is used as the ground conductor for all surge and transient suppression
circuitry internal to the RS500. Surge Ground is connected directly to the safety ground
terminal internally.
NOTE: Since the Chassis Ground is connected to the equipment ground bus internally, HIPOT
testing cannot be performed in the field.
