be performed only by qualified personnel.
Factory-recommended test procedures included in the instruction manual should be
followed. Always disconnect electrical power before working on the unit.
CAUTION:
a) Class I motor must be connected to protective earth via low resistive path (< 0.1ohm)
b) Any motor used must be of a suitable rating.
c) Motors may have hazardous moving parts. 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 on inverter mounting, starting on page 2–6. 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. Using 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 mains
supply close to the inverter. Additionally, a protection device meeting IEC947-1/
IEC947-3 must be fitted at this point (protection device data shown in page 2–13).
NOTE: The above instructions, together with any other requirements are highlighted in
this manual, and must be followed for continued LVD (European Low Voltage Directive)
compliance.
