Electrical connection and setup of the motors must be done in accordance with the manual of motor manufacturer.
Manuals are added to the product as well as are available on motor manufacturer’s website and:
www.selt.com → PRODUCTS → AUTOMATION
Environmental conditions of increased threat:
bathrooms and showers, kitchens, garages, cellars, saunas, rooms for domestic animals, operating theatres in hospitals,
pump rooms, heat exchange rooms, spaces limited by conducing areas, campsites, open spaces, etc. are regarded as
environments with increased threat conditions.
In rooms and spaces where there are increased threat conditions, automatic devices for switching off power supply to the
damaged product should be used, e.g. residual current devices. They are recommended to be used in bathrooms, kitchens,
garages and cellars. Are They are obligatory to be used at swimming and shower pools, saunas, construction sites, while
supplying appliances in open spaces, on agricultural and horticultural farms, on campsites and in camper vans, as well as in
rooms where there is fire hazard.
4.6.2. START-UP AND ADJUSTMENT
extreme position (up and down movement of the slats) are protected by limit switches that need to be adjusted
during the installation,
adjustment of limit switches must be done in accordance with motor’s maintenance manual,
prior to the first start of the product electrical measurements should be performed,
do not start the engine without checking the correctness of system installation.

DT-E 1.1: SUN PROTECTION SCREEN –VENETIAN BLINDS C50 Slim
Issue 2 / April 2017 / EN page 16 / 25
When the product starts working attention should be paid to:

The engine has a thermal switch, which turns off the drive after about 4 minutes of continuous work to
protect against overheating. After turning off by the thermal protection appropriate time should pass
before turning on again, depending on the type of engine and ambient temperature (about 16
minutes).
