WDG-V UOP AC Mains Supply Connections
Do not run control unit AC mains supply wiring in the same conduit
with other AC line power wires. By keeping this wiring separated, you
prevent transient signals from reaching the control unit.
The WDG-V can operate using either 115 VAC, ±10 % or 230 VAC
, ±10 %
. There
is no power switch or circuit breaker on the analyzer, and it must be protected
by installing it on a circuit-protected line, maximum 15 amperes, with a switch
or circuit breaker in close proximity to the control unit and within easy reach of
an operator. Mark the switch or circuit breaker as the control unit disconnect-
ing device.
Mains supply connections to the control unit are as follows:
• L – Line connection
• N – Neutral connection (USA)
• Chassis Stud – Equipment ground (protective conductor)
Use the 1/2" conduit entry hole in the WDG-V UOP for AC mains supply wiring.
Use the chassis stud next to the 1/2" conduit entry hole for equipment ground
(protective conductor).
AC
(
L
) and (
N
) markings are provided by the terminal block for connection of
AC power. These markings are for reference purposes only, such as for use on
system wiring diagrams, etc. The system/product has or needs no specific
LINE
or
NEUTRAL
connection for any function, safety or otherwise. The (
N
) terminal
is not internally grounded, nor needs to be. The system will operate normally
regardless of what AC input terminal (
L
or
N
) the
AC Line
or
Neutral
is con-
nected to, or, if there is a Neutral used at all (i.e., 208 VAC US power connec-
tion).
