MOUNTING PLATE AT LAMINATIONS
1. Remove the large rectangular knockout in the
mounting plate as shown in Fig. 4.
2. Hold the transformer so the clamp on the end bell
faces you.
3. With the keyhole slots up, fit the mounting plate
over the primary leadwires and end bell. Insert
small tab at the bottom of the plate into the slot in
the transformer mounting foot.
4. Insert the mounting screw (supplied) through the
holes as shown in Fig. 5. Secure the plate to the
transformer, but do not overtighten the screw.
MOUNTING TRANSFORMER AND PLATE ON OUTLET BOX
The mounting plate can be mounted on 4 in. square
boxes, 2 x 4 in. rectangular boxes, and on 4 in. octagonal
boxes. See Fig. 4.
1. Align the plate with the box to determine the correct
mounting holes. The mounting feet and secondary
terminals are outside the box.
2. Remove the mounting hole knockouts, if necessary.
Mount the plate on the outlet box using two screws
(obtained locally).
Mounting Through Outlet Box Knockout Hole
The transformer can be mounted on an outlet box using
the clamp on the primary end bell. The mounting plate is
not used. To mount the transformer on an outlet box:
1. Turn the clamp screw almost all the way out.
2. From outside box, thread the primary leadwires
through suitable 7/8 in. knockout. Fit the clamp and
screw through the knockout. Do not mount the
transformer through a plastic knockout.
3. Tighten the clamp screw securely against the rim of
the knockout. Avoid damaging the leadwires with
the screwdriver.
Fig. 4. Use screwdriver to pry out both
sections of knockout.
