4. CONNECTION AND START-UP
4.1 Connecting the mechanical system
CAUTION
Cutting and crushing hazard when removing the fan
from the packaging
→ Carefully remove the device from its packaging, holding it
by the centre of the blades only. Make sure to avoid any
shock.
→ Wear safety shoes and cut-resistant safety gloves.
CAUTION
The blades of the impeller could be damaged.
→ Set down the fan carefully on a soft surface. Make sure the
blades are not subjected to load.
→ After installation, make sure the impeller moves easily
and that the blades of the impeller are not deformed or bent
and do not catch anywhere.
NOTE
Damage to device from vibration
Bearing damage, reduced service life
→ Forces or impermissibly high vibration levels must not be
transmitted to the fan from system components.
→ If the fan is connected to air ducts, it should isolated from
vibrations, for example using compensators or similar
elements.
→ Fasten the fan to the substructure without distorting it.
;
Check the device for transport damage. Damaged devices must no
longer be installed.
;
Install the undamaged device according to your application.
NOTE
Motor capacitor
→ The product is equipped with a motor capacitor with safety
protection class P0/S0 according to EN 60252-1. Take this
into consideration when fitting it to the end product on the
basis of applicable regulations.
CAUTION
Possibility of damage to the device
Serious damage may result if the device slips during assembly.
→ Keep the device fixed in position at the installation location
until all attachment screws have been tightened.
●
The fan must not be strained on fastening.
4.2 Connecting the electrical system
DANGER
Electric voltage on the device
Electric shock
→ Always install a protective earth first.
→ Check the protective earth.
DANGER
Incorrect insulation
Risk of fatal injury from electric shock
→ Use only cables that meet the specified installation
requirements for voltage, current, insulation material, load etc.
→ Route cables such that they cannot be touched by any
rotating parts.
DANGER
Electrical load (>50 µC) between mains wire and
protective earth connection after switching of the supply
when switching multiple devices in parallel.
Electric shock, risk of injury
→ Make sure that sufficient protection against accidental contact
is provided.
Before working on the electrical connection, the
connections to the mains supply and PE must be shorted.
CAUTION
Electrical voltage
The fan is a built-in component and features no electrically
isolating switch.
→ Only connect the fan to circuits that can be switched off with
an all-pole separating switch.
→ When working on the fan, you must switch off the
installation/machine in which the fan is installed and secure it
from being switched on again.
NOTE
Water penetration into leads or wires
Water enters at the cable end on the customers side and can
damage the device.
→ Make sure that the cable end is connected in a dry
environment.
Connect the device only to circuits that can be switched off
using an all-pole disconnecting switch.
