Protection against Hazardous Touch Voltages

No hazardous touch voltage is produced when the signal conditioner is used with appro-
priate current transformers according to the specifications. Secondary voltage is a low
voltage level. The following fault cases can result in high voltage levels:

• Open current path for one or more transformers

• General insulation fault

Negative Power Values

If power measurements yield negative power values, check whether you have connected
the corresponding current transformer or Rogowski coil with the correct orientation.
