SJ300 Inverter
iii
CAUTION:
a) Motor must be connected to protective ground via low resistive path (< 0.1Ω)
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: The end application must be in accordance with BS EN60204-1. Refer to the
section “
Step-by-Step Basic Installation” 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 indepen-
dent means of mechanical support. Using a termination with cable support (figure below), or
strain relief, cable clamp, etc.
CAUTION: A three-pole disconnection device must be fitted to the incoming main power
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 “
Determining Wire and Fuse Sizes”
on page 2–14).
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) compli-
ance.
