B) Ac Wiring - Whelen Engineering Company WPS-2900 Series Installation Manual

b) AC Wiring

An AC Service (Single Phase only) with an acceptable disconnect is required. A 15 amp
(minimum) 120 VAC circuit is recommended.
Locate the service on the pole according to local codes, taking care that the service entrance
will meet height requirements once the pole is set into place.
The WPS-2900 includes a 15 amp, 120 VAC outlet. The cabinet's battery charger plugs into
one of the receptacles. The remaining receptacle is available for use by service personnel
(see "Fig. 14: AC Outlet Installation" on page 29).
NOTE: A section of up to 24 inches of metal bonded seal tight conduit may be utilized
where conduit connections to the siren case assembly are not conveniently
accomplished with rigid steel conduit and fittings.
Each WPS-2900 siren system is supplied with a Lightning arrestor which is to be installed
on the AC service. Local codes should be reviewed and followed to establish the connection
of this device on the primary or secondary side of the disconnect.
NOTE: The location of the siren site should be reviewed for the quality of the AC
service. AC power sources that are subject to excessive power surges or
transients are not acceptable.
The AC charger is simply plugged into an AC duplex outlet (factory included) installed as
follows:
1. Remove the cover from the 4" x 4" box.
2. Position the 3/4" knock-out in the box above the 3/4" knockout in the cabinet.
3. Attach a flex fitting (not included) through the cabinet and the box. This will secure
the box to the cabinet.
4. Connect the AC service to the leads on the cover assembly.
5. Attach the cover to the box.
6. Attach ground wire (GREEN) to cabinet ground stud above the installed outlet.
