Electrical Installation Requirements
IMPORTANT: Electrical ratings are subject to
change. Refer to serial decal for electrical ratings
information specific to your machine.
Machines equipped with an AC inverter drive require a
clean power supply, free from voltage spikes and
surges. Use voltage monitor to check incoming power.
The customer’s local power company may provide
such a monitor.
Input Voltage Requirements
If input voltage measures above rated maximum
voltage, ask the power company to lower voltage.
For voltages above or below listed specifications,
contact Customer Service or a distributor for buck/
boost transformer recommendation. Refer to
Electrical Specification section.
If machine is intended for four-wire service, a neutral
leg must be provided by power company.
If a delta supply system is used on a four-wire model,
connect high leg to L3.
IMPORTANT: Alliance Laundry Systems
warranty does not cover components that fail as a
result of improper input voltage.
IMPORTANT: Improper connections will result in
equipment damage and will void warranty.
IMPORTANT: For machines with X voltage: If
input power is single-phase, connect L1 to R of
terminal block and L2 to S of terminal block. Leave
T unconnected on the input terminal block. If input
power is three-phase, connect L1, L2 and L3 to R, S
and T of the terminal block.
Circuit Breakers
Single-phase machines require a single-phase inverse-
time circuit breaker. Three-phase machines and
variable-speed machines require a separate, three-
phase inverse-time circuit breaker to prevent damage
to the motor by disconnecting all legs if one should
be lost accidentally. Check the nameplate decal on
the back of the machine. Refer to Table 9 through
Table 16 in this section for model-specific circuit
breaker requirements.
Hazardous Voltage. Can cause shock,
burn or cause death. Allow machine
power to remain off for two minutes prior
to working in and around AC inverter
drive.

WARNING
Hazardous Voltage. Can cause shock,
burn or death. Verify that a ground wire
from a proven earth ground is connected
to the lug near the input power block on
this machine.

WARNING
Hazardous Rotation Speed. Will cause
serious injury when controlling AC
inverter drive with a parameter unit,
safety features are bypassed allowing
basket to rotate at high speeds with the
door open. Place large sign on front of
machine to warn people of imminent
danger.
