Checks before installation

Carefully read these assembly and use instructions before beginning
installation of the control unit.
The manufacturer declines all responsibility and obligation of warranty
if any arbitrary changes in construction are made without previous
written authorisation or installation not compliant with the assembly
instructions is executed.
The plant manufacturer must ensure that the EMC directives, low
voltage directives, machinery directives and directives on construction
products are observed.
ATTENTION!
This control unit cannot be used in areas at risk of explosion.
ATTENTION!
Connect the power supply cable to terminal X1 (L1, L2, L3) and to the
PE terminal of the main board.
The power supply cable must be protected on-site with 3 x 10 HV
fuses.
The fuse must have a value such that the gearmotor makes the fuse
trip if it becomes blocked.
WARNING! To avoid the damage of the motor as the result of the loss
of one phase of the 3-phase motor supply, it is necessary to install a
phase loss detector on the power line. This device is not provided with
the product, and should be purchased separately by the installer.
