4 Cable and Wiring
4.1 Electrical safety
To avoid electrical hazards please note the following:
• Do not access the inside of any electrical equipment. Refer servicing to
Void-approved service agents.
4.2 Cable considerations for fixed installations
We recommend specifying installation-grade Low Smoke Zero Halogen (LSZH) cables
for permanent installations. The cables should use Oxygen Free Copper (OFC) of grade
C11000 or above. Cables for permanent installations should be compliant with the
following standards:
• IEC 60332.1 Fire retardancy of a single cable
• IEC 60332.3C Fire retardancy of bunched cables
• IEC 60754.1 Amount of Halogen Gas Emissions
• IEC 60754.2 Degree of acidity of released gases
• IEC 61034.2 Measurement of smoke density.
We suggest using the following maximum copper cable lengths to keep level losses below 0.6
dB.
