B. CONDUIT CONNECTION, WIRING, AND BATTERY INSTALLATION
1. Connect enclosure to wiring system in accordance with the National Electrical Code
®
plus any
other applicable codes.
NOTE:
The N2LPS SS power supply is supplied with one Cooper Crouse-Hinds SSTG2
Myers
™
Hub (
3
⁄
4
”) and grounding bushing already installed. Use a thread sealant in conduit-to-
hub joint to maintain maximum environmental protection.
2.
Make all wiring connections following wiring diagram located on power supply battery bracket
(see Figure 3).
NOTE:
Although generally not required, the interior assembly may be removed to facilitate
wire pulling. Remove four (4)
1
⁄
4
-20 screws and lock washers and disconnect wire leads at
the pilot light, DC disconnect switch, pushbuttons, and lamp heads. DO NOT handle interior
roughly or place it in an area where dirt, dust, or grime will damage it. Replace as soon as all
wiring has been pulled into enclosure.
INSTALLATION
A. INSTALL N2LPS SS SYSTEM
1. Refer to overall dimensions (see Figure 1) to select a mounting location that will provide suitable
strength and rigidity for supporting power supply and attached fixtures.
2. Loosen (do not remove) the captive cover screws (6) of the N2LPS SS power supply housing and
carefully place the cover aside for reassembly later.
3. Securely fasten the power supply enclosure to the mounting location using the appropriate length
1
⁄
4
” diameter hardware through the four (4) mounting holes shown in Figure 1.
2a
. Connect 120 VAC primary (through designated disconnect) to terminal 120. Connect 230 VAC
primary (through designated disconnect) to terminal 230. Connect 277 VAC primary (through
designated disconnect) to terminal 277. Connect common to terminal COM. Connect all
equipment grounding conductors to terminal GRD.
2b
. Connect battery connector to circuit board (see Figure 3). Lamp heads will
not
light at this time.
Verify that transformer connector is also connected to circuit board.
2c
. Standard N2LPS12222 SS system is provided with two factory-assembled and factory-wired
lighting fixture heads. (No additional fixture wiring connections need to be made by the installer).
2d
. Test wiring for correctness with continuity checks and also for unwanted grounds with insulation
resistance tester.
2e
. If NOT installing remote fixture assemblies for connection to the N2LPS SS power supply, proceed
to Section C, “Complete Installation.”
2f
. If additional remote fixture heads are to be connected to the N2LPS SS power supply, refer to
installation instruction sheet IF 1605 (supplied with N2RF Series Remote Fixture Assemblies) and
Table 2 on page 4.

WARNING
To avoid explosion, electrical power must be turned OFF before and during installation and maintenance.
WARNING
To avoid potential explosion, make wiring connection using methods that comply with the NEC and
any local codes.
To prevent dangerous electrical shocks, use N2LPS SS only on grounded wiring systems.
CAUTION
To avoid impairing operation and/or damage to the equipment, mount the enclosure with the back
wall fastened to the vertical surface with the pilot light and push-to-test pushbutton located on the
right side of the enclosure.
WARNING
To avoid explosion, electrical power must be turned OFF before and during installation and
maintenance, and installation area must be free of hazardous atmospheres before wiring.

4. Adjust the lighting fixtures:
a.
Loosen (do not remove) the gland
nut and the lock nut at the
mounting bracket center (see
Figure 2).
Adjust fixture head and bracket to
the desired position and re-tighten
the two nuts.
b.
Loosen (do not remove) the screws
on both sides of the light fixture
(adjusting screws).
Adjust fixture head to desired position and
re-tighten the two screws.
