Electric shock hazard!
Disconnect the power supply before you open the
device.
Only skilled qualified electricians are allowed to
work in areas marked as having electrical voltage.
Unauthorised persons must not enter areas, open
cabinets or work on components where an elec-
trical voltage is present and which are hence
marked with this symbol.
General warning
Read the operating and installation manual before
commissioning and before you open the casing.

WARNING!
Danger due to illegible signage!
Over time, stickers and signs may fade or
become otherwise illegible, meaning that hazards
cannot be identified and necessary operating
instructions cannot be followed. There is then a
risk of injury.
–
Ensure that all of the safety, warning and
operating information is clearly legible.
–
Replace illegible signs or stickers immedi-
ately.

Safety and correct use
General safety notes
DANGER!
Risk of injury from the damper blade of the
VAV terminal unit
The damper blades of VAV terminal units close or
open extremely quickly (
∡
90° within 3 seconds)
and may crush your hands and arms.
Connect ducts to both ends of a VAV terminal
unit; if one end cannot be ducted, at least fit a
perforated plate to prevent people from reaching
into the terminal unit.
CAUTION!
Risk of injury from the casing cover falling
shut
An open casing cover may suddenly fall shut and
crush your fingers.
–
Secure an open casing cover with a bracket.
–
Wear protective gloves.
NOTICE!
Risk of damage to property due to large tem-
perature differences
If any electronic components have been kept in
an unheated area, condensation may form and
damage the electronic components beyond
repair.
–
Before you start commissioning, make sure
that all devices have warmed up to ambient
temperature. Only after about 2 hours will
the system have reached room temperature.
