Chapter 14 Maintenance and upgrades

This section describes maintenance information and upgrade procedures for the meter.

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

•Do not attempt to service the meter. CT and PT inputs may contain hazardous currents and voltages.

•Do not perform a dielectric (hi-pot) or Megger test on the meter. High voltage testing of the meter may damage it.

•Before performing hi-pot or Megger testing on any equipment in which the meter is installed, disconnect all input and output wires to the meter.

Failure to follow these instructions will result in death or serious injury.

Maintenance

The meter does not contain any user-serviceable parts. There are no moving parts inside the meter that require cleaning.

•Do not open the meter. Opening the meter will void the warranty.

•Only manufacturer-authorized service personnel should service the meter.

Contact your local sales representative or Technical Support if the meter requires servicing.

Wrench icon

The wrench icon appears on the top corner of the display screen to alert you of an overvoltage condition or a potential hardware or firmware problem in the meter that requires attention. It could also indicate that the energy LED is in an overrun state.

Navigate to Maint > Diag > Meter to view details of the meter status. Make note of the information shown on the screen, then contact Technical Support.
