DANGER!!
THE UPS CONTAINS POTENTIALLY LETHAL VOLTAGES INSIDE, EVEN IF
THE UNIT IS NOT CONNECTED TO AN EXTERNAL SOURCE OF POWER.
ALL INSTALLATION AND SERVICE PROCEDURES SHOULD BE
PERFORMED BY QUALIFIED PERSONNEL ONLY.
The input power circuit is supplied by the customer. This provides power from the
building source to the UPS system. This circuit should be a dedicated branch circuit that
is hard wired in conduit. Size the branch circuit feeder conductors according to the
specific power rating of the unit. Refer to the latest edition of National Electric Code
(NEC) for the exact wire size required.
An insulated grounding conductor must be installed as part of the input circuit. Size the
grounding conductor in accordance with NEC and local codes. The manufacturer
recommends a parity-sized ground, with respect to the input power wires.
3-1 INSTALLATION OF EQUIPMENT (continued)
The UPS is designed to provide superior isolation and protection for sensitive loads.
The UPS can be wired as a separately derived source that allows the re-establishing of
the ground reference at the output of the UPS. This method of installation will provide
additional load isolation from noise and other disturbances.
DANGER!!
INSURE THAT ALL CODE REQUIREMENTS ARE FOLLOWED IN GROUNDING THE
UPS AND ITS LOADS. BODILY INJURY OR DAMAGE TO EQUIPMENT MAY
OCCUR IF UNIT IS NOT PROPERLY GROUNDED.
NOTE
The equipment to be connected to the UPS may require special grounding procedures.
Refer to technical documentation which accompanies that equipment.
