WARNING: Rotating shafts and above-ground electrical potentials can be hazardous.
Therefore, it is strongly recommended that all electrical work conform to the National
Electrical Codes and local regulations. Installation, alignment and maintenance should
be performed only by qualified personnel.
CAUTION:
a) Class I motor must be connected to earth ground via low resistive path (<0.1 )
b) Any motor used must be of a suitable rating.
c) Motors may have hazardous moving path. In this event suitable protection must be
provided.
CAUTION: Alarm connection may contain hazardous live voltage even when inverter is
disconnected. When removing the front cover for maintenance or inspection, confirm
that incoming power for alarm connection is completely disconnected.
CAUTION: Hazardous (main) terminals for any interconnection (motor, contact
breaker, filter, etc.) must be inaccessible in the final installation.
CAUTION: This equipment should be installed in IP54 or equivalent (see EN60529)
enclosure. The end application must be in accordance with BS EN60204-1. Refer to the
section "Choosing a Mounting Location" on page 2-9. The diagram dimensions are to be
suitably amended for your application.
CAUTION: Connection to field wiring terminals must be reliably fixed having two
independent means of mechanical support. Use a termination with cable support
(figure below), or strain relief, cable clamp, etc.
CAUTION: A double-pole disconnection device must be fitted to the incoming main
power supply close to the inverter. Additionally, a protection device meet IEC947-1/
IEC947-3 must be fitted at this point (protection device data shown in "Determining
Wire and Fuse Sizes" on page 2-17).
NOTE: The above instructions, together with any other requirements highlighted in
this manual, must be followed for continue LVD (European Low Voltage Directive)
compliance.
