6. ASSEMBLY / INSTALLATION
6.1. SAFETY PRECAUTIONS
- Assembly may be carried out only by technically qualified personnel, whereby this manual
and the applicable specifications must be adhered to.
- Assemble the unit with the correct locking/torque wrench.
- Check the 4 mounting points with which the fan is secured to the ceiling/wall.
- Safety guards and similar which are disassembled for installation must be immediately returned
to their proper position after installation and before reconnection to the power supply.
- The fan units must be installed in such a way that their positioning and stability are always
guaranteed during operation.
6.2. SECURING THE UNIT
The mounting place, as regards conditions, must have ambient temperature and surrounding medium, be suitable
for the fan unit in question (see also Point 3)
The bearings may be damaged by pressure, causing fatigue fractures whereby the fan unit's
operation may be obstructed.
Vibrations, increased power consumption and smoke are some of the possible results.
For this reason, no force should be applied to the fan unit via installation components. The ceiling must be flat at
the places where the fan unit is secured.
6.3. ELECTRICAL CONNECTION
6.3.1. SAFETY PRECAUTIONS
The electrical installation of the fan unit and its components may only be carried out by specially
trained professionals, under compliance with this manual and applicable specifications.
The following standards and guidelines must be adhered to:
• IEC 364/DIN VDE 0100 ; DIN 57105, part 1 / VDE 0105, part 1; EN 60204, part 1 / VDE 0113, part 1.
• Specifications of the local energy company, EN 1010.
For protection against unexpected start-up, installations must be assembled in conformity with
EN 60204/DIN VDE-113 (such as lockable inspection switches).
6.3.2 MOTOR/MOTOR CONNECTION
The motor connection must take place in accordance with the attached connection diagram (see connection
diagram sheet).
