Watt Drive V2500 Series Manual page 4

CHAPTER 0: PREFACE
DANGER!
!
A charge may still remain in the DC-link capacitor with hazardous voltages even if
the power has been turned off. To avoid personal injury, please ensure that power
has turned off before operating AC drive and wait ten minutes for capacitors to
discharge to safe voltage levels.
!
CAUTION!
Proper grounds, disconnecting devices (e.g. fuses) and other safety devices and
their location are the responsibility of the user and are not provided by WATT
DRIVE Antriebstechnik GmbH.
!
CAUTION!
Rotating shafts and electrical potentials above ground level can be hazardous.
Therefore it is strongly recommended that all electrical work conform to the national
electrical codes and local regulations. Installation, maintenance and alignment
should be performed by qualified personnel only.
Factory recommended test procedures included in this instruction manual should be
followed. Always disconnect electrical power before working on the unit.
!
DANGER!
a) Any motor used must be of suitable rating.
b) Motors may have hazardous moving parts so that suitable protection must be
provided in order to avoid injury.
!
CAUTION!
Alarm connections may have hazardous live voltages even when the inverter is
disconnected. In case of removing the front cover for maintenance or inspection,
confirm that incoming power for alarm connections is surely disconnected.
! CAUTION!
There are highly sensitive MOS components on the printed circuit boards.
components are especially sensitive to static electricity.
components, do not touch these components or the circuit boards with metal
objects or your bare hands.
CAUTION!
!
Ground the V2500 using the ground terminal.
with the laws of the country where the AC drive is to be installed. Refer to Basic
Wiring Diagram (Chapter 3).
! CAUTION!
The final enclosures of the AC drive must comply with EN50178. (Live parts shall be
arranged in enclosures or located behind barriers that meet at least the
requirements of the Protective Type IP20 Main terminals or other hazardous
terminals for any interconnection (terminals for connecting the motor, contact
breaker, filter etc.) must be inaccessible after installation.. The top surface of the
enclosures or barrier that is easily accessible shall meet at least the requirements of
the Protective Type IP40). (V2500 series corresponds with this regulation.)
CAUTION!
!
The rated voltage of power system that is installed on AC drive must be equal to or
less than 240 Volts (400 / 460V model is 480 Volts) and the current must be equal
to or less than 5000A RMS.
The grounding method must comply
