HAZARDOUS VOLTAGE
• Read and understand this bulletin in its entirety before installing
or operating ALTIVAR 58 drive controllers. Installation,
adjustment, repair, and maintenance of the drive controllers must
be performed by qualified personnel.
• Disconnect all power before servicing the drive controller. WAIT
THREE MINUTES until the DC bus capacitors discharge, then
measure DC bus capacitor voltage between J2-4 (+) and J2-5 (-)
for drive controllers ATV58U09M2 and U18M2, or between
J2-5 (PA) and J18-7 for all other ALTIVAR 58 drive controllers, to
verify that the DC voltage is less than 45 V. Refer to the bus
voltage measurement procedure on page 8.
• DO NOT short across DC bus capacitors or touch unshielded
components or terminal strip screw connections with voltage
present.
• Close the door before applying power or starting the drive
controller.
• User is responsible for conforming to all applicable code
requirements with respect to grounding all equipment.
• Many parts in this drive controller, including printed wiring boards,
operate at line voltage. DO NOT TOUCH. Use only electrically
insulated tools.
Before servicing drive controller:
• Disconnect all power.
• Place a “DO NOT TURN ON” label on the drive controller
disconnect.
• Lock disconnect in open position.
Electrical shock will result in death or serious injury.
