INSTALLATION
Mounting
1.
If refractor guard (P55) is required and not factory installed,
it may be easier to install now. The guard can be installed
anytime during or after the luminaire installation (see
REFRACTOR GUARD INSTALLATION section).
2.
Attach 4 mounting brackets to back of luminaire with
hardware provided. Rotate to desired position and tighten
to 45 in.-lbs.
3.
Mark and drill desired location on mounting surface.
4.
Secure luminaire to surface using 5/16” (8 mm) bolts or lag
screws (not included).
Wiring
5.
Completely loosen the 2 captive cover screws and swing
open the cover.
6.
For a restricted breathing installation, seal per the
RESTRICTED BREATHING SEALING section. Then
continue to step 7.
7.
Connect supply wires to luminaire leads per the attached
wiring diagrams using methods that comply with all applica-
ble codes. Tighten all electrical connections.
8.
Install lamp. See LAMP INSTALLATION AND REPLACE-
MENT section.
9.
For CPMVFB emergency luminaires, connect the emer-
gency ballast connector (white/red wires). This is discon-
nected to avoid discharging the battery during shipment.
10. Close all unused conduit openings with pipe plugs provided.
To prevent galling, lubricate pipe plugs with Crouse-Hinds
HTL lubricant before installing. Tighten plugs securely, with
at least three threads engaged.
11. Close cover and securely tighten the 2 cover screws. For
proper gasket seal, torque the screws to 30 in.-lbs (3.4
N·m).
12. Turn power on.
Restricted breathing sealing (Suffix S826(TB))
Note:
Utilizing the Restricted Breathing feature will result in a
cooler
luminaire Maximum Temperature Identification
Number or T-Number. See luminaire nameplate for
T-Number information.
A)
Threaded Rigid Metal Conduit Wiring Method
Requirements for Restricted Breathing
When wiring with conduit, all conduit entries used must be
sealed. Use one of the following two sealing methods to main-
tain the restricted breathing integrity of Crouse-Hinds CPMVF(B)
luminaires:
Sealing Method 1:
For Conduit. Seal according to NEC
505-15 (c) using Listed Conduit Entrance Seals. Seal all
entries used.
Sealing Method 2:
For Conduit. Alternate Sealing Method
using an Electrical Sealing Putty as follows:
1. A maximum of six (6) #12 AWG conductors can be
sealed in each conduit entry.
2. Form the Electrical Sealing Putty into a ball at least 1
inch (25.4 mm) in diameter.
3.
Surround each conductor with the Electrical Sealing
Putty and form into a ball, making sure the conductors are
separated.
4. Carefully push the Electrical Sealing Putty and
conductors back into the conduit keeping it flush with the
end of the conduit. Make sure the sealing material sur-
rounds all conductors providing a good seal between the
conductors and the conduit.
5. Repeat steps 1 through 4 for each entry used.
The Electrical Sealing Putty found to be acceptable for
maintaining the restricted breathing characteristics of the
CHAMP-PAK series CPMVF(B) luminaire is listed in Table 1.
Table 1
B)
Cable and Cable Gland or Fittings Wiring Method
Requirements for Restricted Breathing
When wiring with cable, use Cable and Cable Glands or Fittings
that are suitable for restricted breathing. Install according to
instructions supplied with the gland or fitting. Repeat for each
entry used.
C)
All unused conduit / cable entries must be closed up.
Close with pipe plug supplied with unit. To prevent
galling, lubricate pipe plugs with Crouse-Hinds HTL
Lubricant before installing.
D)
If the protection method used requires a test port, an
unused conduit opening may be used as a test port.
Mark test port by attaching self-adhesive label supplied
with luminaire next to the test port.
CPMVFB SERIES PUSH-TO-TEST SWITCH
A remote push-to-test switch (not supplied) suitable for the
classified area must be wired in the supply circuit to periodically
test the emergency operation feature (See wiring diagram).
Crouse-Hinds recommends a Crouse-Hinds EDSC2192 for
Class I, Division 2, Groups B,C,D applications.
REFRACTOR GUARD (P55) INSTALLATION
Note: It is not necessary to open or remove the cover to install
the optional refractor guard, catalog number P55. No additional
hardware is needed to attach the guard. To install:
1.
Remove the bottom cover screw and set aside.
2.
Position the guard at the left side of the luminaire, with the
hook to the right and the face of the guard toward the wall.
Place the hook of the guard on the lower hinge pin, just
above the hinge hook. Swing the guard over the refractor.
3.
Reinstall the bottom cover screw through the guard screw
tab and the housing screw hole.
4.
Tighten the cover screw to 30 in.-lb. (3.4 N·m) torque.
WARNING
To avoid explosion,
the wiring methods used must
maintain the integrity of the Restricted Breathing light
luminaire.
