5.3 Electrical connection
5.3.1 General requirements
WARNING
: INSTALLATION AND CONNECTION TO THE ELECTRICAL INSTALLATION
SHOULD COMPLY WITH THE REQUIREMENTS OF THE PN-EN/IEC 60079-14 STANDARD.
WARNING:
IT IS FORBIDDEN TO MAKE ANY CHANGES TO THE FACTORY CONNECTIONS
IN THE LUMINAIRE
.
The power cables have to be introduced into the right lighting system by using of certified cable glands. After making
the cable connections, you need to clamp the cable gland by tightening the cable gland nut with a wrench. During
tightening, protect the cable gland from turning with a second wrench. Clamping the cable gland is designed to protect
the power cable against tearing out and against water and dust ingress inside the luminaire.
WARNING:
FAILURE TO COMPLY WITH THE ABOVE NOTICE MAY DAMAGE THE SEALS,
THEREBY REDUCING THE DEGREE OF PROTECTION AGAINST INGRESS OF DUST AND
WATER (IP) AND THUS EXPLOSION SAFETY.
Use power cables with the following parameters:
•
Single core cross-section 1.5-4 mm
2
– for luminaires powered on one side;
•
Single core cross-section 2.5-4 mm
2
– for pass-through or crossed powered luminaires;
•
Outer diameter of the cable: 8-17 mm
– the value depends on the size and type of cable gland.
The maximum through-currents are:
•
I
max
= 12 A for L, N, PE pass-through or crossed connections;
•
I
max
= 8 A for L1, L2, L3, N, PE pass-through or crossed connections.
WARNING:
THE ABOVE VALUES MUST NOT BE EXCEEDED. AS THIS MAY LEAD TO A
DECREASE IN THE SAFETY OF THE LUMINAIRE. THE MANUFACTURER DOES NOT BEAR
ANY RESPONSIBILITY IN SUCH CASES.
5.3.2 Execution of luminaire electrical connections

the upper frame (reflector), tilt the reflector, cable terminals are mounted below on the lower base.
Remove 8-10 mm of insulation from the wires
then connect to the cable terminals in accordance with the markings
placed on the cable terminals.
