Installation manual

Before you begin
Read and understand these instructions before performing any procedure using
this drive.
DANGER
RISK OF ELECTRIC SHOCK
Read and understand this manual before installing or operating the Altivar 71 drive.
Installation, adjustment, repair, and maintenance must be performed by qualified
personnel.
The user is responsible for compliance with all international and national electrical
standards in force concerning protective grounding of all equipment.
Many parts in this variable speed drive, including printed wiring boards, operate at line
voltage. DO NOT TOUCH.
Use only electrically insulated tools.
DO NOT touch unshielded components or terminal strip screw connections with
voltage present.
DO NOT short across terminals PA and PC or across the DC bus capacitors.
Install and close all the covers before applying power or starting and stopping
the drive.
Before servicing the variable speed drive:
- Disconnect all power.
- Place a “DO NOT TURN ON” label on the variable speed drive disconnect.
- Lock the disconnect in the open position.
Disconnect all power including external control power that may be present before
servicing the drive. WAIT 15 MINUTES to allow the DC bus capacitors to discharge.
Then follow the DC bus voltage measurement procedure on page 19
to verify that the
DC voltage is less than 45 V. The drive LEDs are not accurate indicators of the
absence of DC bus voltage.
Failure to follow these instructions will result in death or serious injury.
CAUTION
IMPROPER DRIVE OPERATION
If the drive is not turned on for a long period, the performance of its electrolytic
capacitors will be reduced.
If it is stopped for a prolonged period, turn the drive on every two years for at least
5 hours to restore the performance of the capacitors, then check its operation. It is
recommended that the drive is not connected directly to the line voltage. The voltage
should be increased gradually using an adjustable AC source.
Failure to follow these instructions can result in injury and/or equipment damage.
