Safety instructions
The electrical installation of this product requires special skills in electrical engineering. These
skills are usually taught during vocational training in the indicated professions and are not
described separately here.
It is only permitted to perform electrical installation in systems with an all-pole
interrupting device for disconnection from the power supply with a gap construction
of at least 3mm.
The following safety information must be checked and observed before any work may be
carried out on the control and the door air curtain:
- Disable the system’s power and secure it against being re-enabled
- The electrical installation is as shown in the component drawing included with the
devices.
- Carry out the electrical installation only in compliance with the currently valid VDE and
EN directives as well as the TABs (technical connection conditions) of the regional
electricity board
- Only connect the device to permanently-installed cables
Incorrectly connected products may become damaged! The manufacturer will not be liable
for injuries and material damage caused if the device has been wrongly connected and/or
incorrectly used
11. Commissioning

Has the unit been mounted to the ceiling properly using the corresponding fixing
brackets?
Electrical installation:
- Have the cables been laid in accordance with the environmental conditions and the
valid regulations?
- Have all of the cores been laid in accordance with the electric circuit diagrams?
- Has the earth wire been laid and clamped throughout?

Safety temperature limiter
Tandem 300-Electro door air curtains are equipped with safety temperature limiters (STL).
They are used to protect the heat exchanger and the unit from overheating. The STL turns
off the electric heating coil if the temperature controller fails and the temperature exceeds
50 °C +/- 5 K. Here, the fans continue running. Each fan is equipped separately with a STL.
The STL will only be turned on again once sufficient cooling time has elapsed, if the power
supply has also been manually interrupted.
