CAUTION
When installing units in a hazardous area,
make sure all installation components selected
are labeled for use in such areas. Perform
installation and maintenance only when the
area is known to be non-hazardous.
Installation in a hazardous area could result in
personal injury or property damage.
CAUTION
Always turn off the power to the sensor before
you attempt any type of wiring. Wiring of
powered equipment could result in personal
injury or property damage.
Disconnect power from the ROC or FloBoss
unit before installing or removing from service
the MVS205 sensor to avoid damage to the
sensor.
Do not reverse polarity of the power wires (+
and —) while wiring the Remote MVS units, or
circuits in the Remote MVS and elsewhere may
be damaged. Double-check for proper
connections before applying power.
To avoid circuit damage when working inside
the unit, use appropriate electrostatic
discharge precautions, such as wearing a
grounded wrist strap.
Do not exceed the maximum differential and
static pressure ranges listed on the label of the
MVS205 sensor.
