Electrical Safety

The cabinet of the Data-Voice-Video 3G Power Solutions (UL-Listed Models) dc power system is a fire
enclosure as specified in UL 60950-1.

All power sources must be isolated before internally servicing the equipment.

The dc power system must be connected to a suitable and readily accessible disconnect device(s).

The dc power system is not compatible with IT (Impedance Terra) ac supply. For advice see Worldwide
Support on page
85 .

A registered electrician (or suitably qualified person) must check the integrity of the installed cabling,
BEFORE the dc power system is powered up.

Tasks must be performed in the sequence documented in this guide.

Location and Environment

The DV2-3G must be installed in a Restricted Access Location (dedicated equipment rooms, equipment
closets, or similar) in accordance with the U.S. National Electric Code (NEC), ANSI/NFPA No. 70, and
according to the applicable local codes.

For ease of access and to maintain optimum system cooling, observe the clearances stated on page 14 .

