General Precautions - Read These First! 2
!WARNING Rotating shafts and above-ground electrical potentials can be hazardous.
Therefore, make sure that all electrical work conform to the National Electrical
Codes and local regulations. Installation, alignment and maintenance must 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 protec-
tion 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 The equipment is intended for installation in a cabinet. The end application
must be in accordance with BS EN60204-1. Refer to the section "Choosing a
Mounting Location" on page 27. The diagram dimensions are to be suitably
amended for your application.
!Caution Connection to field wiring terminals must be reliably fixed having two indepen-
dent means of mechanical support. Use a termination with cable support (fig-
ure 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 2-3-6
Determining Wire and Fuse Sizes on page 37).
Note The above instructions, together with any other requirements highlighted in
this manual, must be followed for continue LVD (European Low Voltage Direc-
tive) compliance.
