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 PD6928 loop-powered
flow rate/totalizers, the hazardous location
installation instructions for the transmitter,
PD6928 loop-powered flow rate/totalizer, and
associated apparatus (barrier) must be
compatible.
•
PD6928 loop-powered flow rate/totalizers 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.
Installation
To access the connectors, remove the enclosure
cover and unclip the display module by pulling it from
the enclosure. The display module may be
disconnected from the options module to facilitate
wiring to the options module.
Refer to Control Drawing DW2636 (contained within
) for details related to intrinsically safe field
wiring.
Explosion-Proof / Dust-Ignition Proof / Flame-Proof
•
Disconnect from supply before opening
enclosure. Keep cover tight while circuits are live.
Conduit seals must be installed within
18" (450mm) of the enclosure.
Unpacking
Remove the meter from box. Inspect the packaging
and contents for damage. Report damages, if any,
