DANGER!
Risk of injury due to rotat-
ing parts
When switching on the fan
without protective grille, there
is a considerable risk of in-
jury.
Remove all foreign ob-
jects from the fan be-
fore switching on.
Install the protective
grilles before switching
on.
Do not get into the fan
or impeller.
Wear protective
gloves.
5.7.1 Vibration Values
The fan must not be subjected to vibra-
tion or shock loads at any stage of life.
Inadmissible vibration values can cause
the fan to be broken and destroyed. The
result may be property damage and per-
sonal injury.
During commissioning, therefore, a
measurement must be carried out on
the flange bearing of the fan. The vibra-
tion values detected must be within the
following limits.

14694:2003 (E), category BV-3)

Prerequisite
•
Measuring instrument
To measure the vibration values, do
the following:
1. Place the measuring instrument at
the measuring point on the flange
end shield. The measurement
should be carried out as close to
the warehouse as possible. Ob-
serve the figure below.
