Connect the motors to the electronic control unit using cables with
section of 1.5 mm². Respect the clamps as follows:

The following prescription must be respected (IEC 64-8):
- Connect the motors earth (yellow-green cable) to an efficient
earth plant.
- Install an omnipolar switch upstream from the plant with an ope-
ning distance of 3 mm or more between the contacts.

Also remember that the large
temperature differences between the
summer and winter cause different
dilation of materials, including those with
which the motors are built. For this
reason it is recommended to control the
regulation of the motor thrust at the start
of the winter and the summer.

ADJUSTMENT OF THE MOTORS STRENGTH
The SERAI CR/41 control unit allows:
A- adjustment of the motors strength by acting on the "Power" potentiometer in the control unit
B- programming of the slowing which prolongs the life of the motor avoiding the gate banging against the
mechanical stops
If slowing has been inserted, the motor has less strength and therefore the gate, if not well-done,
may stop before having completed the manoeuvre.
By excluding the slowing the gate bangs against the mechanical stops causing a, more or less, loud
noise, according to installation. Also, the internal gears are subject to greater stresses.
