Electrical installation
The installation, which should be preceded by
an isolator switch with a contact separation
of at least 3 mm, should only be wired by a
competent electrician and in accordance with
the latest edition of IEE wiring regulations.
The air curtain has an integrated PC board
which is connected to the selected external
control system FC. FC must be ordered
separately. FC is supplied pre-programmed.
Communication- and sensor cables are
connected to the PC board.
Should more than one air curtain be
controlled by a single FC, an additional
communication cable FCBC per unit will be
required. See manual for FC.
Vertical mounting
Control is supplied by 230V~ to the terminal
block. The PC board is accessed via cable glands
on the top or bottom of the unit. Pierce the
gland with a screwdriver before entering the
cable. If necessary, the cables can be routed
through the unit. Bundle the cables inside the
unit to prevent that they will be drawn into
the fans or get in contact with the heating
elements.
