Caution:
To avoid damage from overheating or unit failure, assure that there is sufficient temperature

Minimizing EMI and RFI
When wires run for a significant distance in an electromagnetic field, electromagnetic interference (EMI)
can occur. Strong EMI (e.g. lightning or radio transmitters) can destroy the units and can pose an electrical
hazard by conducting power through lines and into the system. Poor quality or worn wiring can result in
radio Frequency interference (RFI). To minimize the effects of EMI and RFI, consult your reseller.
