WARNINGS
Read this manual carefully before any operation.
Please keep this instruction manual for future use.
The Electrical and Hydraulic connections must be carried out by competent, skilled
personnel in possession of technical qualification required by the specific legislation in force.
The term
skilled personnel
means persons that, because of their training, experience and instruction, as
well as their knowledge of the relevant standards, regulations and accident prevention rules and working
conditions, have been authorized by the person responsible for safety of the plant to perform all the
appropriate activities required, and thereby are able to recognize and prevent potentially dangerous
situations.
(For the definition of skilled personnel see IEC 364).
The technician must ensure that the installation of power supply is provided of an efficient earthing system,
conforming to the regulations in force in the country where the product is installed.
For installation of the power supply, we recommend to use a high sensitivity residual current device with
∆
=30 mA (class A or AS).
To improve immunity to the possible noise radiated on other equipments we recommend to power the PWM
with a separate wire.
Failure to comply with the safety regulations not only causes risk to personal safety and damage to the
equipment, but also invalidates every right to assistance under warranty.
