• The fan must be installed according to the air direc-
tion label on the fan.
• The fan must be connected to duct or equipped with
a safety grille.
• The fan should be installed in a safe way and make
sure that no foreign objects are left behind.
• The fan should be installed in a way that makes ser-
vice and maintenance easy. N.B.! Consider the
weight and size of the fan.
• The fan should be installed in a way that vibrations
not can be transfused to duct or building. To provi-
de this, use for example a flange.
• Regulating the speed can
be done with the built-in
potentiometer, 0-10 V.
An external potentiome-
ter can be connected to
the terminal if necessary.
The internal potentiome-
ter should then be dis-
connected.
• A wiring diagram is applied on the inside of the junc-
tion box or separately enclosed.
• Control that the fan is installed and connected elec-
trically in the right way grounded and with motor
protection.
• RKB 500x250 D1 EC, RKB 600x300 A1 EC,
RKB 600x350 A1 EC, RKB 700x400 B3 EC, RKB
800x500 B3 EC and RKB 1000x500 C3 EC has a
potentional free alarm relay that breaks at max AC
250 V 2A, ”K1”. RKB 300x150 B1 EC och RKB
400x200 C1 EC has a speed signal which reduces
max 3mA, one pulse per turn.
• Electrical installations must be made by an authori-
zed electrician.
• Electrical installations must be connected to a local-
ly situated tension free switcher or by a lockable
head breaker.
• For single-phase fans a residual current circuit brea-
ker i used (type A).
• For 3-phase fans a residual current circuit brea-
ker i used (type B).
EMC-COMPATIBLE INSTALLATION
OF EXTERNAL CONTROL LINES
The control cable may not be longer than 30 m. Scree-
ned control cables must be used when the cable length
is longer than 20 m. When using a shielded cable con-
nect the shielding to one side only, i.e. only to the devi-
ce with the protective ground (keep cable short and
with as little inductance as possible!).
Pay attention to sufficient distance from power lines
and motor wires to prevent interferences.
•
Attention!
Ensure correct polarity!
Never apply line voltage to analog inputs!
