NOTICE
External leads must be shielded and the shield must be grounded at both ends. Terminate each lead with a 320VAC,
150 Joules metal oxide resistor (MOV), or equivalent, at the remote end. Attach MOVs between the leads and
ground. Failure to properly shield and protect leads c an result in equipment damage and/or unintentional operation.
