Additional Safety Information
Before you begin
Verify that the system is free from all short circuits and grounds, except those grounds installed
according to local regulations (according to the National Electrical Code in the U.S.A., for instance). If
high-potential voltage testing is necessary, follow recommendations in equipment documentation to
prevent accidental equipment damage.
Before energizing equipment:
• Remove tools, meters, and debris from equipment.
• Close the equipment enclosure door.
• Remove ground from incoming power lines.
• Perform all start-up tests recommended by the manufacturer.
Operation and Adjustments
The following precautions are from the NEMA Standards Publication ICS 7.1-19 5 (Eng lish versio n
prevails):
• Regardless of the care exercised in the design and manufacture of equipment or in the selection
and ratings of components, there are hazards that can be encountered if such equipment is
improperly operated.
• It is sometimes possible to misadjust the equipment and thus produce unsatisfactory or unsafe
operation. Always use the manufacturer’s instructions as a guide for functional adjustments.
Personnel who have access to these adjustments should be familiar with the equipment
manufacturer's instructions and the machinery used with the electrical equipment.
• Only those operational adjustments actually required by the operator should be accessible to the
operator. Access to other controls should be restricted to prevent unauthorized changes in
operating characteristics.
WARNING
UNGUARDED MACHINERY HAZARD
• Do not use this product with equipment which does not have point-of-operation protection.
• Do not reach into equipment during operation.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.
