WDG-V HP Series and WDG-V/S Series Mains Supply
Connections
The WDG-V HP Series and WDG-V/S Series analyzers can operate using be-
tween 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 disconnecting device.
Mains supply connections to the control unit are:
•
•
•
Use the 1/2-inch conduit entry hole in the WDG-V HP Series and WDG-V/S
Series analyzer for AC mains supply wiring. Use the chassis stud next to the
1/2-inch 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 connect-
ed to, or if there is a Neutral used at all (i.e., 208 VAC US power connection).

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.
L – Line connection
N – Neutral connection (USA)
Chassis Stud – Equipment ground (protective conductor)
