Some drawings in this manual may be shown with protective covers or shields removed, to describe details. These must be
•
replaced before operation.
Observe electrostatic discharge procedures when handling circuit cards to prevent ESD damage.
•
The equipment may start unexpectedly upon application of power. Clear all personnel from the Drive, motor, and machine
•
area before applying power. Secure covers, couplings, shaft keys, and machine loads before energizing the Drive and Bypass
unit.
Please do not connect or operate any equipment with visible damage or missing parts. The operating company is responsible
•
for any injuries or equipment damage resulting from failure to heed the warnings in this manual.
Intended Use
Drives and Bypass Units are intended for installation in electrical systems or machinery.
For use in the European Union, the installation in machinery and systems must conform to the following product standards of
the Low Voltage Directive:
EN 50178, 1997-10, Equipping of Power Systems with Electronic Devices
EN 60201-1, 1997-12 Machine Safety and Equipping with Electrical Devices
Part 1: General Requirements (IEC 60204-1:1997)/
EN 61010, 1997-11Safety Requirements for Information Technology Equipment
(IEC 950:1991 + A1:1992 + A2:1993 + A3:1995 + A4:1996, modified)
Other
The Drive and Bypass unit is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical
amperes, 240 Vac maximum (240 V Class) and 480 Vac maximum (480 V Class) only when option "D" (Fused Disconnect) is
specified.
The above statement remains valid when option "B" is specified, however the statement becomes invalid if option "G" is spec-
ified.
