Connecting Power to the UPS
This section contains the instructions for connecting the UPS to
the Gateway. The UPS requires 120 VAC on the input and
provides 12 VDC output to the Gateway.
Connect the UPS according to the manufacturer's
instructions. Install the UPS only in a well-ventilated
area that is free from explosive or corrosive gases,
vapor, or excessive dust, dirt, and moisture. Ensure a
free flow of air around the UPS.
Wiring the AC-Power for the UPS and Gateway must be
done by a licensed electrician. Install in accordance with
the National Electrical Code, Canadian Electrical Code,
and local electrical codes
.
The integrity of the protective earthing should be
ensured when installed.
The AC input to the UPS must have a readily accessible
disconnect device installed.
