1. WARNINGS
1.1 General warnings
•
The Power+ drive must be fi tted by professionally qualifi ed personnel on a
complete unit or system as part of a fi xed installation.
•
This device features dangerous voltages, and consequently failure to
observe the instructions contained in this user manual may cause serious
harm to people and damage to things.
•
The system design, installation, commissioning and maintenance of
the drive are operations that are reserved solely for qualifi ed personnel,
who understand all of the safety warnings, installation, operating and
maintenance instructions contained in this user manual code +0300050EN,
available, including prior to purchase, at www.carel.com, under “Literature”.
1.2 Fundamental safety rules
Before performing any maintenance work:
•
disconnect Power+ and external control circuits from the power
supply, moving the main system switch to “off ”; wait at least 5 minutes;
•
always check, using a suitable multimeter, that there is no dangerous
voltage across the terminals;
•
always make sure the motor has stopped completely. Motors that
are still freely rotating may produce dangerous voltages at the Power+
terminals, even when this is disconnected from the power supply;
•
check the temperature of the heat sink: coming in contact with the
heat sink may cause burns.
When Power+ is connected to the mains, motor terminals U, V, W are
live, even if the motor is not running.
Do not measure insulation resistance or dielectric rigidity directly on
Power+, or with Power+ connected.
The control terminals are isolated from the mains voltage. Nonetheless,
the relay outputs may have a dangerous control voltage even when Power+
is not connected to the mains.
The level of safety provided by the enabling inputs on Power+
(excluding the “Safety Torque Off ” input when used in compliance with the
standards) is not suffi
cient in critical applications without adopting
further independent safety measures. For all applications where malfunctions
may cause serious harm to people and damage to things, the risks must be
assessed and additional safety measures adopted
Observe all the general and local safety standards concerning
installations of high voltage devices, as well as the regulations for the correct
use of the personal protective equipment.
Use this device only for the purposes specifi ed by the manufacturer.
Do not make any modifi cations or replace any components unless
recommended by the manufacturer, as these actions may cause fi re, electric
shock or other damage.
