Electrical Supply and Wiring to the Air Curtain
All electrical wiring and connections MUST be carried out by a competent qualified electrician in
accordance with the latest edition of the IEE wiring regulations and/or local statutory regulations.
A 1 phase or 3 phase local disconnect having a contact separation of at least 3mm on all
poles must be fitted in the electrical supply to the air curtain and located in an accessible
position adjacent to the unit. Units with dual electrical supplies (see * in Table below)
must have a common disconnect to switch off both supplies simultaneously.
The appliance must be connected by cables having an appropriate heat resistant
temperature rating.
All supply cables, circuit breakers and other electrical installation equipment must be
correctly sized for the air curtain model being installed; see section 3: Specifications.
Models operating on a 480V or 600V, 3 phase electrical supply - see section 3:
Specifications, Electrical Supply * – also need a separate 208V to 240V electrical supply
to operate fan motors and controls.
A 25mm / 1in size cable gland or conduit connector should be used for the Electrical
Supply into the air curtain.
The air curtain must be grounded.
