For directly mounting the luminaire to a cable tray or similar
no brackets are supplied and the fixture can be secured
directly using the 4 TORX screws supplied, refer to table
for tightening torques. Rear access required.
Option 2. Ceiling or Flat Wall Mounting
Assemble the mounting brackets to the luminaire with the 4
TORX screws supplied, refer to table for tightening torques.
Use the dimensions in Option 2 to locate the luminaire into
the desired position. Maximum screw/bolt size 8mm (not
supplied).
Assemble the 30° angled mounting bracket to the
luminaire with the 4 TORX screws provided, refer to table
for tightening torques.

Cable Entries and Cables
Continued
Maintenance
Special Conditions for Safe Use
Suitably certified cable entries must be used which include
a sealing washer to maintain the IP66/67 rating of the
enclosure.
The supply to the luminaire must include a fuse which is
capable of interrupting a 1500A short circuit current.
The glands must be suitable for use within an operating
temperature range of -40°C to +80°C.
The gland is required for increased safety protection, the
entry thread shall be suitable sealed (in accordance with
IEC 60079-14) to maintain the ingress protection rating of
the fixture.
When used with steel basket weave armour or braided
(screened) cable the basket weave armour or braid is
unable to carry the cable load without fracture therefore the
cable must be clamped and cleated to prevent pulling on
the cable being transmitted to the cable terminations.
Electrical Connection
See Figure 2. Electrical Connection
When connecting the conductors extra care should be
taken in order to maintain the hazardous protection.
The insulation of the conductors shall reach up to the
terminal block. The conductor itself shall not be damaged.
The connectible minimum and maximum conductor cross
sections shall be observed (see electrical connection data).
Closing the LED Luminiare
Remove any foreign bodies from the fixture
Pay attention when fitting the LED tray to the enclosure,
make sure the seals are clean and undamaged.
