Step 5 Connect the input power as described in the “Wiring the DC-Input Power Source” section.

Wiring the DC-Input Power Source

Before you wire the DC-input power source, review the warnings in this section and this information:

Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than:

10 A Statement 1005

Warning A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. Statement 1022

Warning Only trained and qualified personnel should be allowed to install or replace this equipment. Statement 103

Caution Connect the unit only to a DC-power source that complies with either DC mains or Safety Extra-Low Voltage (SELV) requirements in IEC 60950 based safety standards. Do not connect to a hazardous voltage source.

Caution The DC-power-supply voltage should be within the range that you select on the DC-power-supply voltage switch, either –36 to –72 VDC or +18 to +36 VDC. If the supply voltage is not in this range, the switch might not operate properly or might be damaged.
