The following steps outline the procedure for connecting 
the electrical service to the tumbler.  
NOTE: The wiring diagram is supplied in material 
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 appropriately labeled terminal on the terminal 
block.  The ground wire must be connected to the 
ground connection. Refer to Figure 10. 
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.
b. Disconnect and reverse any two leads at 
connections.
