9.2 Electrical connection
WARNING Electrocution
Before beginning any work on the electric instal-
lation, be sure that main breaker panel switches
are “Off” to avoid any danger of electric shock. All
mounting and plumbing must be completed before
proceeding with electrical hook-up. Where required
by local, state or national electrical codes the circuits
should be equipped with a “ground fault interrupter”.
The unit must be properly grounded in accordance
with state and local codes, or in absence of such
codes, in accordance with national electric code or the
Canadian electric code. Failure to electrically ground
the product could result in serious personal injury or
death.

The connection to the power supply is only permissible
as a permanent connection in conjunction with the re-
movable cable grommet. Ensure the water heater can
be separated from the power supply by an isolator that
disconnects all poles with at least 1/8
˝
(3 mm) contact
separation.
!
Supply this appliance only from a grounded system. A
green terminal (or a wire connector marked “G”, “GR”,
“GROUND”, OR “GROUNDING”) is provided for wiring
the appliance. To reduce the risk of electric shock,
connect this terminal or connector to the grounding
terminal of the electric service or supply panel with a
continuous copper wire in accordance with the electri-
cal installation code.
!
Material losses
Observe the type plate. The specified rated voltage must
match the supply line voltage.
