Safety Information
•
Read complete instructions prior to installation
and operation of the meter.
•
Hazardous voltages exist within enclosure.
Installation and service should be performed only
by trained service personnel.
•
Service requiring replacement of internal
components must be performed at the factory.
•
Control room equipment must not use or
generate more than 250 VRMS or VDC.
•
Hazardous location installation instructions for
associated apparatus (barrier) must be followed
when installing this equipment.
•
For safe installation of an ATEX approved
transmitter in series with PD6606/PD6608 loop-
powered meters, the hazardous location
installation instructions for the transmitter,
PD6606/PD6608 loop-powered meter, and
associated apparatus (barrier) must be
compatible.
•
PD6606/PD6608 Series Loop-Powered meters
do not add capacitance or inductance to the loop
under normal or fault conditions.
•
Substitution of components may impair
hazardous location safety.
•
Equipment contains non-metallic materials and
therefore special care and consideration should
be made to the performance of these materials
with respect to chemicals which may be present
in a hazardous environment.
