Installation precautions
This product has special circuitry to protect it against moderate surges and static discharges.
However, to ensure reliable operation and long service life, it is important to take the
necessary precautions against any spikes, surges and static discharges.
Place the units away from heat sources and allow adequate ventilation.
As much as possible cables should be routed away from any noisy sources and avoiding long
runs in close proximity to AC mains cables.
