6.4 LAMP INSTALLATION & REPLACEMENT (CONTINUED)
4. Remove lamp.
5. Perform cleaning and inspection as noted in the MAINTENANCE section.
6. Screw new lamp into lampholder and securely tighten lamp. New lamp must
be identical type, size, and wattage as marked on the floodlight nameplate.
The lamp must be screwed tightly into the lamp holder. Ensure that it is
screwed in fully so that no arcs or other inadmissible operating conditions
can occur. Protect lamp from glass breakage during installation.
7. Thoroughly clean lens and cover gasket seal with a clean, damp cloth. If this is
not sufficient, use a mild soap or a liquid cleaner such as Collinite NCF or Duco
#7. Do not use an abrasive, strong alkaline, or acid cleaner. Damage may
result.
8. Close floodlight cover door making sure that all wires are safely inside and
positioned away from the ballast area. Securely tighten all cover screws. For
proper gasket seal, torque the cover screws to 10-14 lbs.-in. (1.13-1.58 Nm).
Over-tightening can impair the degree of protection.
6.5 PUTTING INTO OPERATION
Prior to taking the apparatus into operation, the tests specified in the relevant
national regulations shall be carried out. Apart from that, the correct functioning
and installation of the apparatus in accordance with these operating instructions
and other applicable regulations must be observed.
Insulation measurements may only be carried out between PE and the external
conductor • L1 (L2, L3) as well as between PE and N.
- Measurement voltage: max. 1 kVAC/DC
- Measurement current: max. 10 mA
- The floodlight may only be operated when sealed.
- Carry out test in accordance with IEC 60079-15 33.7.1 (see Section 7.1).
7. MAINTENANCE/SERVICING
The relevant national regulations which apply to the maintenance/servicing of
electrical apparatus in explosive atmospheres shall be observed (IEC 60079-19).
Servicing:
When servicing, in particular those components that affect the explosion
protection, will have to be checked, e.g.:
- Housing for any cracks or damages.
- Gaskets for their perfect condition.
- Terminals and blanking plugs for their firm fit.
- Defective lamps must be replaced immediately.
The interval between maintenance depends upon the ambient conditions and the
hours of operation. The suggested interval between lamp changes given by the
lamp manufacturer should be followed. A visual check and the test to IEC 60079-
15 33.7.1 (see Section 6.1) should be carried out every 6 months.
We recommend a regular maintenance according to an approved preventive
maintenance program. To prevent additional lumen depreciation, thoroughly clean
the lens and cover gasket seal with a clean, damp cloth. If this is not sufficient,
use a mild soap or a liquid cleaner such as Collinite NCP or Duco #7. Do not use
an abrasive, strong alkaline, or acid cleaner. Damage may result.
7.1 TEST FOR RESTRICTED BREATHING TO IEC 60079-15
33.7.1:
This test is to be carried out:
- Installation
- Lamp change
- During scheduled maintenance
- Check the lamp holder for damage
- The lamp must be screwed tightly in to the lamp holder
- Tighten all cover screws (over-tightening of the screws can damage the threads)
- Connect test unit to the test point on the luminaire. See Figure 7.
- The time required for a vacuum from 300 Pa (30mm water pressure) to reduce to
150 Pa (15mm water pressure) at constant temperature conditions, may not be
less than 80 sec. (see Figure 7). If the vacuum cannot be maintained for this
length of time, then the seals (enclosure, cable entry, etc.) must be replaced. After
this, the test must be repeated.
8. REPAIR/OVERHAUL/ MODIFICATIONS
Repairs and overhaul may only be carried out with genuine COOPER CROUSE-
HINDS spare parts. Before lamp change or dismantling of individual parts, ensure
that no explosive atmosphere is present. Switch off the apparatus before opening
or isolate before commencing maintenance. Only use original spare parts. If the
floodlight was previously in operation, then wait 15 minutes before opening.
Repairs that affect the explosion protection may only be carried out by COOPER
CROUSE-HINDS or a qualified electrician in compliance with the applicable national
rules.
Modifications to the device or changes of its design are not permitted.
9. DISPOSAL / RECYCLING
When the apparatus is disposed of, the respective national regulations on waste
disposal must be observed. In order to facilitate the recycling of individual
components, plastic parts are provided with the identification mark of the plastic
material used. Subject to modifications or supplement of the product range.
