5 Preparing the product for
use
Any change that is not expressly approved
by the manufacturer will invalidate both
the guarantee and certification.
5.1 Safety precautions before use
Make sure that all the equipment are
certified for the application and for the
environment in which they will be installed.
CAUTION! The electrical system to which the
unit is connected must be equipped with a
15A max automatic bipolar circuit breaker.
The minimum distance between the circuit
breaker contacts must be 3mm (0.1in).
The circuit breaker must be provided
with protection against the fault current
towards the ground (differential) and the
overcurrent (magnetothermal).
A power disconnect device must be
included in the electrical installation, and
it must be very quickly recognizable and
operated if needed.
Before starting any operation, make sure
the power supply is disconnected.
The device can only be considered to be
switched off when the power supply has
been disconnected and the connection
cables to other devices have been removed.
Make connections and tests in the
laboratory before carrying out installation
on site. Use appropriate tools for the
purpose.
Before proceeding with any operations,
make sure that the mains voltage is correct.
Given the considerable weight of the
system, use an appropriate transport and
handling system. The staff must carry out
the handling of the product in compliance
with the common accident prevention
standards.
5.2 Unpacking
When the product is delivered, make sure that the
package is intact and that there are no signs that it
has been dropped or scratched.
If there are obvious signs of damage, contact the
supplier immediately.
When returning a faulty product we recommend
using the original packaging for shipping.
Keep the packaging in case you need to send the
product for repairs.
