Caution - Danger !
Disconnect unit from mains before making any repairs. Only when the BUSS-
capacitors have discharged, (5 minutes after the device has been seperated
from line, the unit may be opened and worked on).
As with any form of electrical equipment, there is always a risk involved in the handling of
electrical machinery. The greatest care must always be exercised during installation and
maintenance. It is recommended that service is performed by authorized personnel only.
Make sure that the unit and the motor is properly grounded in order to avoid electrical hazzards!
Improper grounding will also cause damage to the electronic circuit and to the encoders of the
motor! The common connection of the electronic circuit can be jumpered, connected to ground
with 1MR or 100R.
