2.3 Mechanical Preparation of the
Battery
Cabinet(s)
If batteries are not provided in IPM cabinets, see Disconnect Installation
Drawing at the back of this section for wiring of separate circuit breaker and skip
this Section 2.3. For battery preparation refer to the battery manufacturer’s
manual.
IPM battery trays are shipped screwed to the shelf supports and should be
left fastened down.
1. Fasten leveling feet (packed inside) to the four bottom corners of the
battery cabinet. Access to the inside of the cabinet is not required. Refer to Figure
2-1. (An optional pedestal mount may replace leveling feet and casters.)
a.
First screw the leveling foot screw through the leveling plate.
b.
Use two sets of 1/4-20 x 1” screw, flat washer and lock washer to
fasten the leveling plate to the bottom of the cabinet. Two threaded holes are in the
floor of the cabinet to receive them.
c.
Screw in each leveling foot until it is a minimum of 0.75 in (1.9 cm)
above the floor level. Tighten locking nut to keep it there.
2. If an IPM battery cabinet is to be attached to the left side of the UPS,
remove the fiberboard shipping panels from the left side of the UPS and the right
side of the battery cabinet by forcing out the fasteners. Leave the red glastic panel
attached.
It is recommended that the battery cabinet not be attached to the
right side of the UPS.
a.
If more than one battery cabinet is used, the one with a disconnect
circuit breaker should go adjacent to the UPS. This is Battery Cabinet #1.
3. Remove each left battery cabinet cover by removing screws from the
inside front.
Be very careful not to touch the screwdriver against the battery
terminals.
Then pull side panel forward and lift to remove.
4. In each battery cabinet, cut the straps holding the top tray of batteries If
foam blocks are inside the battery trays, leave them in place. They are to keep
small batteries from moving around inside the trays.
