4.1 Safety notes
DANGER!
Danger of electric shock! Do not touch any live com-
ponents. Electrical equipment carries a dangerous
electrical voltage.
– Only skilled qualified electricians are allowed to
work on the electrical system.
– Switch off the supply voltage before working on
any electrical equipment.
DANGER!
Risk of injury due to stored energy.
Pneumatic actuators are pressurised and can cause
the damper to move abruptly:
– Only qualified personnel may work on the pneu-
matic actuator.
– Switch off the compressed-air supply before
working on any pneumatic equipment.
– After switching off the compressed-air supply,
trigger the actuator to discharge the stored
energy.
4.2 Installation instructions
The shut-off damper was manufactured and configured
on a project-specific basis. If an electric actuator has
been ordered, it is assembled at the factory. For units
with an electric actuator, the supply voltage and the
signal line must be connected. For devices with a pneu-
matic actuator, the compressed-air supply and the com-
pressed-air control line must be connected.
The connection is made in accordance with the infor-
mation on the actuator or connection diagrams in the
product data sheet or commissioning instructions for the
respective actuator, www.troxtechnik.com . The voltage
ranges and the terminal connections specified on the
actuator must be observed!
Personnel:
Skilled qualified electrician
Observe the following during installation:
Legal and official regulations, in particular VDE
guidelines.
Observe the technical connection rules (TCR) of the
local grid operator.
Wiring work for supply voltage and signal lines on
site.
The rating and manufacturing of customer-side con-
nections and wiring must be carried out in accord-
ance with the recognised rules of electrical engi-
neering.
The responsibility for design, dimensioning and
sizing of the electrical and network installations
as well as their execution by others lies with the
specialist consultant, HVAC contractor and commis-
sioning engineer appointed by the system owner.
This includes, in particular, the dimensioning of the
power supplies as well as cable types and cross
sections.
Observe wiring guidelines and project-specific circuit
diagrams.
The electrical connection may only be made after
complete installation of the unit.
For units with a 24 V supply voltage, observe the
following:
– Electrical connection only with safety trans-
former
– Make sure that all connected units have the
same GND reference point for the supply
voltage.
Suitable wire clamping brackets must be provided
for all connecting cables.
Electronic components contain no parts that can be
replaced or repaired by the user and may only be
opened by the manufacturer!
