Electric connection
The fan is supplied without command and control cir-
cuit and without power and signal cables.
Follow the wiring diagram of the electric mo-
tor, which can be found in your enclosed do-
cumentation.
Electric equipment (by the installer):
Do not put any voltage on the fan during in-
stallation
During installation, the qualified installer must
provide a control panel designed and meeting
the requirements of IEC 61439-1, with an IP ra-
ting appropriate for the installation site, and proceed
with the wiring of the fan according to IEC 60204-1
and IEC 60364-X series.
The electric panel must be accompanied by a decla-
ration of conformity with the BT Directive 2014/35/EU
and the EMC Directive 2014/30/EU.
The installer must issue a declaration of correct instal-
lation in accordance with the regulations of the coun-
try in which the fan is installed.
The panel shall be equipped with at least the fol-
lowing components
Incoming power line breaker
Short circuit and overload protection of
the power supply line downstream the
fan (circuit breaker, fuses, etc....)
Start and stop control (buttons, selector,
etc...)
Category 0 emergency stop device of
red mushroom type with yellow back-
ground in accordance with EN ISO
13850 and EN ISO 13849-X
The electric motor plate data and the information gi-
ven in the attached technical documentation must be
used to size the power supply line (see "TECHNICAL
DATA" p. 20).
Power lines must be in accordance with the require-
ments of the laws in force at the place of installation
and must in any case:
64
64
•
be made with cables having a cross-section sui-
table for the power of the fan without producing
overloads and for the length of the line itself to
respect the maximum voltage drop value of 4%;
•
provide an efficient grounding connection;
•
be equipped with power breaking devices and
automatic protection against overload and short
circuits.
In the event of installations not complying with the di-
rections contained in this chapter, Munters' liability, as
well as the fan warranty, the validity of the declaration
of incorporation and the EU declaration of conformity,
shall be null and void.
Refer to the fan wiring diagram before making any
connection (Fig.29-30); also check the efficiency of
the ground system and check the continuity of the
protection circuit installed on the fan.
The electric grounding must be made according to
local regulations before connecting the motor to the
power supply.
For the correct sizing of the protection conductors, the
IEC EN 60204-1 standard:
Minimum protective conduc-
tor cross section [mm
Phase
cross
section SF [mm

Fig.29-30 shows the wiring diagram for the con-
nection of the fan to the mains. However, the diagram
is subject to local laws and regulations and must be
amended, if necessary, to comply with such laws and
regulations.
