NOTE:
Connecting these washers to an IT power supply requires
special consideration.
■
A separate grounding wire is recommended if codes permit.
It is recommended that a qualified electrician determine
the grounding path is adequate.
Electrical Requirements
It Is Your Responsibility:
■
To contact a qualified electrical installer.
■
To be sure that the electrical connection is adequate and in
conformance with the National Electrical Code, ANSI/NFPA
70-latest edition, or Canadian Electrical Code CSA C22.1,
and all local codes and ordinances.
A copy of the above code standards can be obtained from:
National Fire Protection Association, One Batterymarch
Park,Quincy, MA 02269.
■
To supply the required 3 or 4 wire, three-phase, 208–240
volt, 50/60 Hz., AC electrical supply on a separate circuit.
Circuit capacity is dependent on washer size and connection
type and is shown in the table below. A time-delay fuse
or circuit breaker is recommended. Installation of a GFCI
(Ground Fault Circuit Interrupter) is also recommended.
Connect to an individual branch circuit. Do not fuse the
neutral or grounding circuit.
Electrical Connection
The electrical connections were designed per the specifications
provided during the ordering process. Before connecting, verify
the voltage and frequency on the washer label. See the Back
View in “Dimensions and Technical Specifications” to ensure that
the voltage and frequency correspond to your power network.
The connection is described in the illustration below. If the
washer is not equipped with a main switch, power disconnects
are needed for all electrical supplies connected to the washer,
in accordance with item 5.3 in standard EN 60204-1.

Washer Connection to Electrical Network
(With an Earth Leakage Trip)
Inlet Conductors and Power Supply Protection
Inlet conductors of the washer connection to the electrical
network must have copper cores. The cross section of the inlet
conductors depends on the voltage and the unit heating type,
i.e. total electrical input. Circuit breakers or fuses in the laundry
switchboard keep the inlet cable from short-circuiting and
overloading.
See “Technical Specifications” for the corresponding current.
