v
Ambient temperature and relative humidity surrounding the
Controller must not exceed the maximum specified limits.
v
The Controller in its installed state must be protected against
excessive electrostatic or electromagnetic interferences.
ELECTRICAL
v
The Controller must be wired as per wiring diagram & it must
comply with local electrical regulation.
v
The Electrical noise generated by switching inductive loads
might create momentary Fluctuation in display, latch up, data
loss or permanent damage to the instrument. To reduce this use
snubber circuit across the load.
