INSTALLATION
Besides the normal precautions for storage and
handling of electronic equipment, the transmitter
contains static sensitive devices. Since
semiconductors can be damaged by the direct
discharge of static electricity, avoid contact with
terminal block conductors and electronic components
on the circuit board.
When mounting the transmitter, choose a location that
has ample clearance for the removal of the front bezel
and rear cover. The location should provide easy
access for maintenance procedures and not be in a
highly corrosive environment. Excessive mechanical
vibrations and shocks as well as relay and power
switches should not be in the immediate area. Signal
wiring should not be placed in conduit or open trays
that contain power wiring for heavy electrical
equipment. Field wiring should meet wiring practices
appropriate for fieldbus devices (See Supplementary
Documentation).
The transmitter can be pipe, hinge, wall or panel
mounted. Use the appropriate figure below to assist
in the mechanical installation of the transmitter.
