1. WARNINGS
1.1 General
warnings
•
The Power+ drive must be fi tted by professionally qualifi ed personnel inside of a complete unit or inside of a
system as part of a fi xed installation, anyway inside a metal enclousure in compliance with prescription 4.3.7 of EN
61800-5-1 Standard.
•
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 qualifi ed personnel, who understand all of the safety warnings, installation, operating and maintenance
instructions contained in this instruction sheet and in the user manual code +0300048EN, 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 “Safe 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.
•
Ensure correct earthing connections and cable selection as per defined by local legislation or codes. The
drive typically have a leakage current of greater than 3.5mA so that a fi xed installation to power line is
required; furthermore the earth cable must be sufficient to carry the maximum supply fault current which
normally will be limited by the fuses or magnetic MCB. Suitably rated fuses or MCB should be fitted 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 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.
•
IP20 drives must be installed in a pollution degree 1 or 2 environment, mounted in a cabinet with IP54 or
better.
