"U" Bracket Installation in an open ceiling
CAUTION: This unit equipment has a typical weight of 6.5 kg (14.5 lbs).
It can only be installed in an open ceiling that can support this weight, or
an equivalent load pressure of minimum 33 lbs/sq.ft (160 kg/m2)
between two joists.
1. Cut a rectangular opening (8-1/4 inch by 5-3/4 inch) next to the ceiling
joist. The opening must have the short side along the joist. Use the "U"
bracket to mark the dimensions on the ceiling (Figures 2a, b, c).
2. CAUTION : Install a chain or "pencil rod" wires (provided by others) to
a joist above the rectangular opening.
3. Slide the "U" bracket in the opening: enter the flange side first then
push the other side to the joist.
4. Fix the "U" bracket on the joist with appropriate fasteners (not sup-
plied).
5. Check that the four mounting screws are turned 2-3 threads in the
pem-studs.
6. Pass the chain and electrical cable(s) out through the opening.
Equipment preparation (Figure 3)
1. Remove the cover of the transformer box.
2. If the unit requires DC connection: remove the knockout and install a
second conduit bushing (provided in the hardware kit).
3. Disengage the two hooks at the bottom of the housing.
4. For installation in open ceilings: bend slightly the flexible bracket con-
necting the two metal housings to align them roughly along the same
axis.
Equipment installation in the wall (Figures 4 and 5)
1. Suspend the unit upside-down from the "U" bracket using the metal
hooks (see Figure 4). Do not hang the unit directly on the drywall edge
as this can damage the drywall.
2. Pass the electrical cable(s) through the bushings into the unit housing.
3. Connect the GREEN wire from the charger module and the back box
to the GROUND supply wire.
4. Connect the WHITE wire (labelled Neutral) to Neutral.
5. For 120VAC connect the BLACK wire (labelled 120VAC) from the unit
to Line.
6. For 277VAC connect the ORANGE wire (labelled 277VAC) from the
unit to Line.
7. For 347VAC connect the RED wire (labelled 347VAC) from the unit to
Line.
8. If there are any remote heads to be connected to the unit, connect the
RED wire (labelled L+) and the BLUE wire (labelled L-) to the load wires.
9. Make sure all unused wires are properly capped.
10. CAUTION: failure to cap the wires may cause an unsafe condition.
11. If the equipment includes a battery, connect the battery positive wire
(labelled: "Connect battery positive terminal") to the battery or printed cir-
cuit board, as indicated by the second label.
12. Install the door on the housing and secure with the screw.
