Connecting Electrical Service
The following steps outline the procedure for
connecting electrical service to the tumbler.
• 3 Phase models – Each tumbler must be
connected to its own individual branch circuit
breaker, not fuses, to avoid the possibility of
“single phasing” and causing premature
failure of the motor(s).
• Electrical service must be connected using the
appropriate permanent rigid metal conduit
system.
• Service conductors must be copper only.
For an existing service, determine your service voltage
and conductor amperage. Carefully review the tumbler
serial plate ratings and Electrical Requirements
section of this manual. If service is inadequate it must
be upgraded by a qualified electrical contractor. Never
connect an improper or inadequate service to any
machine.
Configuring Your Tumbler for Other
Service Voltages
Several gas and steam tumbler models have been
designed to be field convertible to other service
voltages. Refer to Table 8 for these models:
NOTE: Electric models are not field convertible
and must be connected to service specified on serial
plate.
If tumbler requires conversion for use on another
service voltage, complete the steps detailed in the
Conversion Instructions section prior to connecting
service to machine.
If tumbler does not require conversion or has been
converted according to the Conversion Instructions
section of this manual, continue with step 1.
NOTE: The wiring diagram is located in the upper
junction box or upper contactor box.
1. For new service, install a circuit breaker or fused
disconnect of proper voltage and current rating as
close to each tumbler as possible.
2. Route service conduit from circuit breaker panel
or disconnect panel to tumbler service connection
box. Conduit routing should not obstruct access
for maintenance or servicing. Refer to Service/
Ground Location.
3. Pull conductors through conduit and attach to
circuit breaker and ground connection. Secure
service ground wire to the grounding screw or
lug. Attach service conductors to appropriately
labeled positions on the terminal block. Make
sure all connections are secure.
4. Check electrical service phase sequence (3 Phase
models only) as follows:
a. Energize the electrical service and
momentarily start the tumbler. Check the
direction of cylinder rotation. If the cylinder
rotates clockwise as viewed from the front,
the phase sequence is correct. If the cylinder
rotates counterclockwise, proceed with step b.
b. Disconnect power to machine, disconnect and
reverse the L1 and L2 connections on the
terminal block.
Electrical Connections
All gas and steam tumblers require a single service
connection to TB1 of the upper unit junction box only.
The serial plate reflects current draw, breaker/fuse size
and conductor amperage required for the entire
machine.
All electric tumblers require separate service
connections for each upper and lower unit. Serial Plate
ratings reflect current draw, breaker/fuse size and
conductor amperage required per unit.
