L100 Inverter

iii

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.

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 earth 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: 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 2–7. 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 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 highlighted in this manual, must be followed for continued LVD (European Low Voltage Directive) compliance.
