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