MOUNTING AND WIRING
The 35-63J is not position sensitive and can be mounted verti-
cally or horizontally. The case may be mounted on any surface
with #6 sheet metal screws.
HIGH VOLTAGE TERMINAL CONNECTION
The Fenwal 35-63J uses a Rajah (spark plug) type HV connec-
tion which is common to most controls. If the control being
replaced does not utilize a Rajah connection, the HV spark
cable will need to be replaced or re-terminated using a Rajah
style female mating connector.

CAUTION
Label all wires prior to disconnection when
servicing or replacing controls. Wiring errors
can cause improper and dangerous
operation. A functional checkout of a
replacement control should always be
performed.
WARNING
The control must be mounted and located in
a manner which protects components from
exposure to water (dripping, condensate,
spraying, rain). Any control that has been
exposed to water must be replaced.
WARNING
All wiring must be done in accordance with
both local and national electrical code.
Wiring must be at least #18 AWG rated for
105°C or higher.
WARNING
The 35-63J uses voltages of shock hazard
potential. Wiring and initial operation must
be done by qualified service technician.
WARNING
Operation outside specifications could result
in failure of the Fenwal product and other
equipment with injury to people and
property.
