Electrical installation
The installation, which should be preceded
by an isolator switch with a contact
separation of at least 3 mm/0.12 in, should
only be wired by a competent electrician and
in accordance with the latest edition of IEE
wiring regulations. The control system is pre-
installed in the air curtain with an integrated
control card, (see fig. 2).
SIRe is supplied pre-programmed with
quick-fit connections.
Modular cables are connected to the control
board. See manual for SIRe.
Unit without heating or with water heating
Connected via the built-in SIRe control board
with 2 m/6.6 ft cord and plug.
Unit with electrical heating
The electrical connection is made
on the top of the unit. See Fig.2.
208V3~/480V3~/600V3~ power supply for
heat and control (*1 *2) should be connected
to a terminal block in the primary terminal
box.
Note! If you want to divide
the output between two
connection points, the series cabling
must first be removed (PAEC4020/25E,
2x480V3~/600V3~).
*1 480V3~/ 600V3~ Control supply is
transformed via internal transformer to
230V~ and routed through 2x 10A fuses in the
primary terminal box.
*2 208V3~ Control supply is connected
internally through 2x 10A fuses in the
primary terminal box.
The largest cable diameter for the terminal
block is 16 mm²/0.025 in². The cable
glands used must meet the protection class
requirements. In the distribution board it is
to be indicated that ”the air curtains can be
supplied from more than one connection”.
See wiring diagrams.
Vertical mounting PA4JK
Units from 1.5 metres/4.9 feet and longer may
be used vertically. For vertical mounting, all
units must be supplemented with a vertical
kit containing everything needed for a
practical installation of floor standing units.
The unit can be reversed and placed on
either side of the door. Connections and PC
Board SIRe are positioned near floor level
when the air curtain is placed to the left of
the door and at the top when it is placed to
the right (seen from the inside).
The accompanying floor edging is attached
to the floor with fasteners appropriate to the
surface.
Two units can be mounted directly on top of
each other, the floor edging is then used as a
joining bracket.
The air curtain must be secured to wall or
ceiling.
A design kit which gives a neater installtion
that conceals cables and pipes is available as
accessory, se accessories pages.
See fig. 11 and separate manual.
