1. General safety precautions

"Important instructions for installation safety.
Incorrect installation can cause serious injury"
This installation manual is intended for qualified personnel only.
Installation, electrical connections and adjustments must be performed in accordance
with Good Working Methods and in compliance with the present standards.
Read the instructions carefully before installing the product. Bad installation could
be dangerous.
The packaging materials (plastic, polystyrene, etc.) should not be discarded in
the environment or left within reach of children, as they are a potential source
of danger.
Before installing the product, make sure it is in perfect condition.
Do not install the product in explosive areas and atmospheres: the presence of inflam-
mable gas or fumes represents a serious safety hazard.
The safety devices (photocells, safety edges, emergency stops, etc.) must be installed
taking into account: applicable laws and directives, Good Working Methods, instal-
lation premises, system operating logic and the forces developed by the automation.
Before connecting the power supply, make sure the plate data correspond to that
of the mains power supply. An omnipolar disconnection switch with a contact
opening distance of at least 3mm must be fitted on the mains supply.
Check that there is an adequate residual current circuit breaker and a suitable overcur-
rent cutout upstream of the electrical installation in accordance with Good Working
Methods and with the laws in force.
When requested, connect the automation to an effective earthing system that complies
with current safety standards.
During installation, maintenance and repair operations, cut off the power supply before
opening the cover to access the electrical parts.
The electronic parts must be handled using earthed antistatic conductive arms.
The manufacturer of the motorisation declines all responsibility if component
parts not compatible with safe and correct operation are fitted.
Only use original spare parts for repairing or replacing products.
