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
