Warning
To avoid the risk of fi re, explosion, or electric shock, this product should
be installed, inspected, and maintained by a qualifi ed electrician only, in
accordance with all applicable electrical codes.
All statements, technical information and recommendations contained herein are based on information and tests we believe to be reliable. The accuracy
or completeness thereof are not guaranteed. In accordance with EATON Crouse-Hinds Division "Terms and Conditions of Sale” and since conditions
of use are outside our control, the purchaser should determine the suitability of the product for his intended use and assumes all risk and liability
whatsoever in connection therewith.
- Connect internal grounding continuity wire to cover using screw assem-
bled in the cover (see Figure 6).
- Close ballast housing onto cover module ensuring that all wires are sa-
fely inside and positioned away from the ballast area. Tighten captive
closing screw to 3.4Nm (see Figure 8). Alternative type for closing ba-
llast housing onto the cover is shown in Figure 9, where the Quick-Clip
is used.
- Install lamp as specifi ed on nameplate. See lamp installation and repla-
cement section.
- Install globe and optional guard and/or
refl ector. See the instructions
that follow.
- Connect external grounding (see Figure 10).
Excessive tightening may affect or damage the connection.
Only heat resistant cable/wire Tw>105ºC 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 specifi ed 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 main-
tain 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 ob-
served.
All screws and/or nuts of the supply terminals, also of those remai-
ning vacant, shall be tightened down (torque for terminal screws:
2.5Nm).
6.4 Globe installation
Use G303 globe (large enclosure) and G34 globe (small enclosure)
Globe should be mounted on ballast housing directly (see Figure 11).
- Apply a small amount of HTL® lubricant to the threads of G303 globe.
- Screw the globe into the ballast housing. Hand tighten securely.
6.5 Guard installation
Installation P33 guard (large enclosure see, Figure12).
- Push the wire guard P33 to adapter directly. It is okay when you fi nd the
wire guard P33 in the slot of housing.
Installation P22 stainless steel or aluminum guard shall be assembled with
G251 only (small enclosure, see Figure12).
- To assemble, align correctly then push globe and guard together.
- Apply a small amount of HTL® lubricant to the threads of the guard.
- Screw the globe and guard assembly as a unit into the ballast housing.
Hand tighten securely.
6.6 Refl ector installation
Install dome or angle refl ector by placing the keyway slots over the moun-
ting studs on the ballast housing and rotating clockwise until it "snaps” into
position.
6.7 Lamp installation and replacement
To prevent ballast damage on high pressure sodium luminaire, replace bur-
ned out lamps as soon as possible.
To avoid shortened lamp life, lamp holder failure, wiring faults, or ballast
failure, secure lamp fi rmly and completely.
- Disconnect power to luminaire and allow to cool completely.
- Remove globe or guard if used.
- Remove lamp.
- Perform cleaning and inspection as noted in the Maintenance/Servicing
section.
- Screw new lamp into lamp holder and hand tighten securely. New lamp
must be identical type, size, and wattage as marked on the luminaire
nameplate.
- Thoroughly clean or replace the globe gasket seal.
- Apply a small amount of HTL® lubricant to the threads of the globe and
guard (if used) or refl ector.
- Screw the globe and guard (if used) and refl ector (if used) into the ba-
llast housing and hand tighten securely. Refer to the sections 6.4, 6.5
and 6.6 above for more information.
6.8 Operation
Prior to putting the light fi ttings into operation, the tests specifi ed in the
relevant national regulations shall be carried out.
In addition to this, the correct functioning of the light fi tting shall be chec-
ked in accordance with these operating instructions and other applicable
regulations.
Insulation measurements may only be carried out between PE and the
external conductor L as well as PE and N.
- Measurement voltage:
Max. 1kV AC/DC.
- Isolation:
Min. 2MΩ.
The luminaire may only be operated when closed.
It is generally recommended (see IEC/EN60079-14) that you ensure that
the restricted breathing of the construction is not impaired during installa-
tion and that you test the restricted breathing properties before commissio-
ning (see Section 9).
Improper installation and operation of the luminaire leads to loose of the
guarantee.
7. Maintenance / servicing
The relevant national regulations which apply to the maintenance/servicing
of electrical apparatus in explosive atmosphere shall be observed (IEC/
EN60079-17).
Before opening the enclosure, it is necessary to ensure that the voltage
supply has been isolated and should allowed to cool down for 10 minutes
after switching off.
Make sure globe or refl ector and lamp are cool when performing mainte-
nance.
During maintenance, the parts affecting the level of protection must be
checked; in particular:
- Enclosure and glass for cracks and damage.
- Seals for damage.
- Terminal, screw glands, and blanking plugs for secure fi tting.
To maintain the light output, clean the protective glass and refl ector with a
damp cloth or a mild cleaning fl uid.
The interval between maintenance depends upon the ambient conditions
and the hours of operation. The recommendations given within IEC/EN
60079-17 for recurring checks must be observed.
If the luminaire is opened for maintenance purposes or to replace the lamp,
ensure that the "nR” properties are not affected.
This could be done by testing the restricted breathing properties as per
Section 9.
The suggested interval between lamp changes given by the lamp manufac-
turer must be followed (see Section 6.7 for details).
After replacing the lamp, ensure that the "nR" properties have not been
affected. This could be done by testing the restricted breathing properties
as per Section 10, for example.
8. Repair / overhaul / modifi cations
Repairs and overhaul may only be carried out with genuine EATON
Crouse-Hinds Series spare parts.
Before replacing or disassembling individual parts, observe the following:
Disconnect the power supply to the equipment before maintenance/repair.
Only use original spare parts. If the luminaire was previously in operation,
wait 10 minutes before opening.
Repairs that affect the explosion protection may only be carried out by
EATON Crouse-Hinds Division or a qualifi ed electrician in compliance with
the applicable national rules.
Modifi cations to the device or changes to its design are not permitted.
After carrying out repair or overhaul work, ensure that the "nR" properties
have not been affected.
This could be done by testing the restricted breathing properties as per
Section 10, for example.
9. Testing restricted breathing properties
All screw plugs and cable glands must be correctly tightened.
Over-tightening the screw elements can destroy the thread.
Connect the testing equipment to the test port on the luminaire (see Fig.13).
Use the values specifi ed in IEC/EN 60079-15 for the test.
10. Disposal / Recycling
When the apparatus is disposed of, the respective national regulations on
waste disposal must be observed.
Subject to alteration or supplement of this product without any advertise-
ment before.
Save these instructions for future reference.
