Wiring and Electrical Connections

Select wiring and/or cable glands that
are rated for the environment of use
(such as hazardous area, ingress
protection and temperature). Failure
2 to use properly rated wiring and/or
cable glands can result in personal
injury or property damage from fire or
explosion.
Wiring connections must be in
accordance with local, regional, and
national codes for any given
hazardous area approval. Failure to
follow the local, regional, and national
codes could result in personal injury
or property damage from fire or
explosion.
To avoid personal injury resulting
from electrical shock, do not exceed
maximum input voltage specified in
table 1-2 of this quick start guide, or
on the product nameplate. If the input
voltage specified differs, do not
exceed the lowest specified maximum
input voltage.
Personal injury or property damage
caused by fire or explosion may occur
if this connection is attempted in a
potentially explosive atmosphere or in
an area that has been classified as
hazardous. Confirm that area
classification and atmosphere
conditions permit the safe removal of
the terminal box cover before
proceeding.

The digital valve controller is normally powered by a
control system output card. The use of shielded cable
will ensure proper operation in electrically noisy
environments.
Note
Connect the digital valve controller to
a 4-20 mA current source for operation
in the point-to-point wiring mode. In
the point-to-point wiring mode, the
digital valve controller will not operate
when connected to a voltage source.
