Recommendations for wiring installation
• Keep the CN3 connector cables as short as possible.
• Try not to pull on the cable along the power line. The cables should be laid separately at a distance of over 30 cm. Cable
crossing is feasible.
• Where the cable along the power line is pulled, insert the cables through a metal pipe, earth one end of the pipe and
install a safety device such as an earth leakage breaker or smoke detector.
