Cable Entries (Kle) And Blanking Plugs; Electrical Connection - Cooper Crouse-Hinds NVMV Série Instructions D'installation Et De Maintenance

6.2.3.3 CEILING AND WALL MOUNT COVER
Alternate sealing method for ceiling mount and wall mount. There are
more than four entries in ceiling or wall mount cover.
- Choose the entry to assemble the cable gland.
- Apply a small amount of HTL
and tighten the cable gland to the entry. Be sure there is a
gasket installed between the gland and housing.
- Insert suitable cable through gland and tighten the cable to the
gland.
- All entries shall be sealed to restrict the entry of gases and
vapors.
- All unused entries must be sealed with suitable plug.
6.3 CABLE ENTRIES AND BLANKING PLUGS
The cable gland shall have a degree of protection of IP66 or higher.
Unused entries shall be closed with certified blanking plug in order to
establish the minimum protection category.
The authoritative mounting guidelines for the cable glands used must
be observed.
Over-tightening might impair the protection category.
!
Attention: ensure that during tightening of the cap nut, com-
plete cable does not start turning.
6.3.1 "nR" RESTRICTED BREATHING
The restricted breathing (nR) properties must be preserved when us-
ing cables and wires of sufficient diameter (see IEC/EN60079-14).
If the cable glands included in the scope of delivery are replaced with
other cable glands, the "nR" properties must be checked before
operation.
A restricted breathing test may be carried out per Section 10.
6.3.2 "tD" DUST
If the cable glands included in the scope of delivery are replaced with
other cable glands, the cable glands and blanking plugs must be used
in compliance with IEC60079-31.

6.4 ELECTRICAL CONNECTION

6.4.1 GENERAL
!
The electrical connection of the luminaire must only be
established by qualified electricians.
Be certain electrical power is OFF before and during installation

and maintenance.
Luminaire must be supplied by a wiring system with an
equipment grounding conductor.
6.4.2 ELECTRICAL CONNECTION
- Hang ballast housing on the cover module hinge hook (see
Figure 5).
- Connect supply wires to luminaire wire leads (or terminals) per
the attached wiring diagrams using methods that comply with
all applicable codes (see Figure 7, Figure 14, and Figure 15).
Tighten all electrical connections.
- Connect internal grounding continuity wire to cover using
screw assembled in the cover (see Figure 6).
- Close ballast housing onto cover module ensuring that all wires
are safely inside and positioned away from the ballast area.
Tighten captive closing screw to 3.4Nm (see Figure 8). Alterna-
tive type for closing ballast housing onto the cover is shown in
Figure 9, where the Quick-Clip is used.
- Install lamp as specified on nameplate (see lamp installation
and replacement section).
- Install globe or refractor and optional guard and reflector. See
the instructions that follow.
- Connect external grounding (see Figure 9).
!
Excessive tightening may affect or damage the connection.
Only heat resistant cable/wire according to the data on the
nameplate can be used for the electrical installation.
Make sure the supply voltage is the same as the luminaire
voltage.
Use only the lamp and wattage specified on the luminaire
nameplate.
Connect cable/wire according to the terminal numbering and
circuit diagram.
The conductors shall be connected with special care in order to
maintain the explosion category.
The insulation of the conductors shall reach the terminal.
The conductor itself shall not be damaged.
The connectible min. and max. conductor cross-sections shall be
observed.
All screws and/or nuts of the supply terminals, also of those
remaining vacant, shall be tightened down (torque for terminal
screws: 2.5Nm).
