1. WARNINGS
1.1 General warnings
•
The Power+ drive must be tted by professionally qualied personnel inside of a complete unit or inside of a
system as part of a xed installation, anyway inside a metal enclousure.
• The Power+ drive must be installed in TT ot TN power supply network and it must be connected permanently
downstream of the main distribution board (overvoltage category III).
• This device features dangerous voltages, and consequently failure to observe the instructions contained in this
instruction sheet and in the 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 qualied personnel, who understand all of the safety warnings, installation, operating and maintenance
instructions contained in this instruction sheet and in the user manual code +0300093EN, 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 “o”; 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 level of safety provided by the Power+ could not sucient 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 if
requested.
•
Ensure correct earthing connections and cable selection as per dened by local legislation or codes. The
drive typically has a leakage current typically greater than 3.5mA so that a xed installation to power line
is required; furthermore the earth cable must be sucient to carry the maximum supply fault current
which normally will be limited by the fuses or magnetic circut brakers (MCB). Suitably rated fuses or MCB
should be tted in the mains supply to the drive, according to any local legislation or codes.
•
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 specied by the manufacturer. Do not make any modications or
replace any components unless recommended by the manufacturer, as these actions may cause re,
electric shock or other damage.
