SAFETY INFORMATION
WARNINGS
 Read complete instructions prior to installation and operation of the meter.
 Installation and service should be performed only by trained service
personnel. Service requiring replacement of internal components must be
performed at the factory.
 Disconnect from supply before opening enclosure. Keep cover tight while
circuits are alive. Conduit seals must be installed within 18" (450mm) of
the enclosure.
 Verify that the operating atmosphere of the meter is consistent with the
appropriate hazardous locations certifications.
 If the meter is installed in a high voltage environment and a fault or
installation error occurs, high voltage may be present on any lead
