3.3 Electrical Supplies
A maximum voltage variation of +6%/-6% on the nominal is expected. The safety limit for T rating is +10%.
3.4 Light Source
The luminaire is fitted with LEDS that can last 120,000 hours depending on ambient temperatures. Therefore depending on the
functionality of the fitting replacement of LED’s will be rare /unnecessary. If the LED assembly needs replaced contact manufac-
turer.
3.5 Mounting
Luminaires should be installed where access for maintenance is practical and in accordance with any lighting design information
provided for the installation. This will usually consist of aiming points and aiming angles. Mounting arrangements should be secured
with lock washers or self-locking nuts and bolts.
CHECK Dust applications limit angle between 120° and -120° to minimise build-up.
3.6 Cabling and Cable Glands
3.6.1 Cable Glands
The installer and user must take responsibility for the selection of cables, cable glands and seals.
The product is dual certified for INMETRO and to comply with the certification for installation cable glands and sealing plugs must
be Certified “Geração E”.
Cable glands and sealing plugs when installed must reliably maintain the IP rating of the enclosure IP66/67.
The cable gland must withstand an impact value of 7Nm where the risk of mechanical damage is high or 4Nm where the risk of
mechanical damage is low.
Sealing plugs must be similarly rated and a tool must be used for their removal. Where the cable is not reliably clamped externally
to the apparatus, the cable gland must clamp the cable against a pull in Newtons of 20x the cable OD in mm for non-armoured ca-
ble and 80x the cable OD for armoured cable. Where brass cable glands are used in a corrosive environment cadmium or nickel
plating should be used. Two tapped cable entries are provided, one with a plug and seal suitable for permanent use, the other has
a travelling plug. M20 x 1.5 entries are standard, other sizes are available on request up to M25 x 1.5p.
3.6.2 Cable
The temperature ratings of the entries at 55ºC ambient requires cable rated at 90ºC. Entry cables must be suitable for 20ºC cable
rise minimum above ambient.
3.6.3 Cable Connection
The cable connections shall only be installed and wired with cable in an ambient temperature of -10°C to +80°C. Unfasten gearbox
lid screws then carefully remove lid to be retained by hanging strap. The maximum conductor size is 6mm². Internal earth point is
provided next to the mains terminal block. The standard looping cable size is up to 6mm². The conductors should be bared back so
that they make full contact in the terminals, but the bare conductor should not be more than 1mm beyond the terminal. Unused
terminal screws should be tightened. The core must be identified by polarity and connected in accordance with the terminal
markings. Before re-fitting the cover, a final check on the correctness of connections should be made. Cover bolt torque 2 Nm.
4.0 Inspection and Maintenance
Individual organisations will have their own procedures for inspection and maintenance. What follows are guidelines based on
ABNT NBR IEC60079-17 and on our experience. Maintenance work and fault finding must be performed by competent personnel
under an appropriate permit to work and with the apparatus isolated. Frequency of maintenance will depend on experience and the
operating conditions.
Luminaire should not be opened when an explosive atmosphere is present.
The service life of the luminaire is 15 years. (120,000 hours of free service at 25°C).
1 Check if any LED’s have failed (not lit).
2 The LEDs are mounted on boards, if there are total of 24 or more LED's not working the light output will have dropped to a
level where the LED board may need replaced, contact manufacturer.
3 Check for mechanical damage/corrosion.
4 Check for loose connections including earthing.
5 Check for undue accumulations of dust or dirt.
6 Verification of tightness of fixing, glands, blanking plugs etc.
7 Check for unauthorised modifications.
8 Check condition of enclosure gaskets and fastenings.
9 Check for any accumulation of moisture.
