3 - PRELIMINARY CHECKS

Before installing this product, verify and check the following steps:
- Check that the gate or door are suitable for automation
- The weight and size of the gate or door must be within the maxi-
mum permissible operating limits specified in Fig. 2
- Check the presence and strength of the security mechanical stops
of the gate or door
- Check that the mounting area of the product is not subject to flood-
ing
- Conditions of high acidity or salinity or proximity to heat sources
could cause malfunction of the product
- Extreme weather conditions (for example the presence of snow,
ice, high temperature range, high temperatures) may increase the
friction and therefore the force required for the handling and initial
starting point may be higher than under normal conditions.

- Check that the manual operation of gate or door is smooth and
friction-free and there is no risk of derailment of the same
- Check that the gate or door are in equilibrium and stationary if left
in any position
- Check that the power line to supply the product is equipped with
proper grounding safety and protected by a magnetothermal and
differential security device
- Provide the power system with a disconnecting device with a gap
of contacts enabling full disconnection under the conditions dictated
by the overvoltage category III.
- Ensure that all materials used for the installation comply with cur-
rent regulations
