2. Warnings and precautions for safe use
Warning: The power unit must be mounted with vertical
orientation and power terminals facing up and never in a
horizontal or inverted position.
The reasons are as follows:
• In water cooled models it is to avoid, in case of losses
that sensitive parts of the machine may come in
contact with the liquid.
• In air models cooled it increases the thermal
efficiency of air flow and ensures the achievement of
the performances mentioned in specification.
Warning: The drive stores high voltage (600 VDC).
Before any intervention on the machine, wait at least 6
minutes after removing the main power.
Warning: Installation should only be performed by
qualified personnel and equipped with the necessary
means of individual protection, but in any cases not before
having read and understood the information contained in
this manual.
Warning: After opening the package you should check
against damages or burned parts. In this case do not power
on the machine or its parts, and contact the supplier.
Warning: Do not expose your device to rain or agents that
may compromise the integrity.
Warning: the inverter and the devices connected to it, in
their normal operation generate magnetic fields. Prevent
access nearby to pacemaker carriers and do not place
equipment sensitive to magnetic fields close to the inverter
or to the welding transformer.
