• Do not touch the terminals on the enclosure as they carry a high voltage. This
may lead to electric shock.
• Perform maintenance and testing after removing the upper level power supply
and verifying that the CHARGE lamp has gone out. There is danger in that a
charge remains in the capacitor. This may lead to electric shock. In any case,
use a voltameter to measure for high voltage prior to performing maintenance.
• Only designated persons should perform maintenance, testing, and parts
replacement. When performing maintenance, remove accessories (watches,
bracelets, etc.) prior to working. Use insulated tools. Failure to do so may lead
to electric shock.
