CHAPTER 4: INSTALLATION

Option 1: Internally Powered

(with Jumper Cable)

24 Vdc

Option 2: Externally Powered (no Jumper Cable)

12.If required, connect the Remote Emergency Power Off ￿ (REPO) circuit. Check national and local codes before wiring.

The output power can be disabled in an emergency by closing a switch connected to the REPO. You must physically reset the system enable switch on the front of the UPS to restart the unit.

•The REPO circuit is considered a Class 2 (UL and CSA standards) and SELV (IEC standard) circuit.

•Class 2 Circuit: Used in North America by UL and CSA. It is defined in the National Electrical Code (NFPA 70, Article 725) and in the Canadian Electrical Code (C22.1, Section 16).

•SELV Circuit: Used in Europe by IEC; acronym for “safety extra low voltage.” A SELV circuit is isolated from primary circuitry through an isolating transformer and designed so that under normal conditions, the voltage is limited to 42.4 V peak or 60 V dc

•Both Class 2 and SELV circuits must be isolated from all primary circuitry. Do not connect any circuit to the REPO terminal block unless it can be confirmed that the circuit is SELV or Class 2. If there is a question, use a contact closure switch.

•Use one of the following cable types to connect the UPS to the EPO switch:

CL2: Class 2 cable for general use.

CL2P: Plenum cable for use in ducts, plenums, and other spaces used for environmental air.

CL2R: Riser cable for use in a vertical run in a shaft of from floor to floor.

CLEX: Limited use cable for use in dwellings and for use in raceways.

For installation in Canada: Use only CSA Certified, type ELC (extra-low voltage control cable).

•Wiring by a qualified electrician is required.

•Connect using Option 1 if internally powered.

•Connect using Option 2 if externally powered.
