The following steps outline the procedure for
connecting the electrical service to the tumbler.
NOTE: The wiring diagram is supplied in
literature packet in cylinder.
1. Install a circuit breaker as close to the tumbler as
possible. If more than one tumbler is being
installed, a disconnect switch or circuit breaker
should be provided for each. This will make it
possible to disconnect each tumbler for
maintenance purposes.
2. Connect the conduit-encased leads to the disconnect
switch, or circuit breaker. Connect the wire leads
to the appropriate labeled terminal on the terminal
block. The ground wire must be connected to the
ground connection as shown in Figure 16.
3. Check the electrical service phase sequence
(three phase only) as follows:
a. Energize the electrical service (on reversing
tumblers, ensure nonreversing is selected) and
momentarily start the tumbler. Check the
direction of the cylinder rotation. If the
cylinder rotates clockwise (viewed from the
front), the phase sequence is correct. If the
cylinder rotates counterclockwise, proceed
with step b.
NOTE: On reversing tumblers, the fan
motor should also rotate clockwise (viewed
from the front) on all models except the
F75 models which rotate counterclockwise
(viewed from the front).
b. Disconnect and reverse any two service leads
on the terminal block.
