2.2 Mounting
This unit is designed for either shelf or wall mounting. A minimum of 6” per side
and 2” above the cabinet is necessary for the cooling and mounting purposes.
Consideration should be given to the proximity of the incoming and output
power.
Caution: Due to the weight of this system (up to 150 lb.) , mounting securely is
extremely important. Standard drywall or bookshelf mounting is not
acceptable. Mounting to the wall studs is required.
External batteries (on a rack or in a cabinet) should be located in an equipment
room per local requirements.
2.3 Wiring
Open the door of the unit after removing the two fastening screws near the right
edge of the door. Four dual concentric knockouts are located on the left side of
the cabinet to install 1/2” or 3/4” conduit to the unit. Run 18 gauge (minimum)
wires through the conduit and connect per Installation Wiring Diagram No.
8022072 at the rear of this manual. The input/output terminal strip TS3 is
located on the left side of the cabinet above the knockouts.
This UPS is provided with external batteries which must be connected to the
unit. Confirm that all sources of power are off and that the battery circuit
breaker on the left side of the cabinet is off ( handle in the down position).
Loosen the outside caps on the plastic feedthroughs located on the left side of
the cabinet and pass the two battery wires (marked POS+ and NEG-) through
the feedthroughs. Connect the wires to the terminal board on the inside rear of
the cabinet, matching the wire markings to the terminals. Close the cabinet
door and replace the two screws near the right hand edge of the front panel.
With the battery system wired ( four batteries in series mounted on an open
rack, or in a prewired battery cabinet), connect the two battery wires from the
UPS to the battery system observing the proper polarities.
WARNING:
The battery system is a hazardous source of power. Make all
connections first before connecting the equipment to the batteries. Connect the
wires at the battery terminal last. Improper polarities will damage the UPS
and/or batteries.
2.4 Startup Procedure
2.4.1 With the battery circuit breaker off ( handle in the down position) and
the load(s) disconnected, apply AC input power.
