2.2.2 DC Power Supply Wiring and Grounding

Figure 2.2.2.1 DC Power supply wiring and grounding diagram

The RS900 low voltage DC power supply features reverse polarity protection and dual independent inputs. This feature allows the connection of two DC sources with the same nominal voltage to provide redundant power supply inputs. The DC source must be connected to the DC inputs according to the polarity markings on the unit.

Notes:

1.Equipment must be installed according to the applicable country wiring codes.

2.Surge Ground should be connected to Chassis Ground via a braided cable or other appropriate ground wire.

3.Chassis Ground must be connected to the protective earth.

4.All line-to-ground transient energy is shunted to the Surge Ground terminal. In cases where users require the DC 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.
