NEW (page 6): Safety / Installation and maintenance work
• After maintaining or modifying a drive safety circuit or changing circuit boards
inside the module, retest the functioning of the safety circuit according to the
start-up instructions.
• Do not change the electrical installations of the drive except for the essential
control and power connections. Changes may affect the safety performance or
operation of the drive unexpectedly. All customer-made changes are on the
customer's responsibility.

Note:
• The Safe torque off function (option +Q967) does not remove the voltage from the
main and auxiliary circuits.
CHANGED (page 10): Safety / Permanent magnet motor
• Ensure that the motor cannot rotate during work. Prevent the start-up of any
drives in the same mechanical group by opening the Prevention of unexpected
start switch (option +Q950) or the Safe torque off switch (option +Q967) and
padlocking it. Make sure that no other system, like hydraulic crawling drives, are
able to rotate the motor directly or through any mechanical connection like felt,
nip, rope, etc.
