■
A separate grounding wire is recommended if codes permit.
It is recommended that a qualified electrician determine
the grounding path is adequate.
NOTE: Connecting these washers to an IT power supply requires
special consideration.
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, single-phase, 208–240
volt, 50/60 Hz., or 3 or 4 wire three-phase 440–480 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.

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.
