DANGER FROM ElECTRICAl TENSION!
Danger to life! Never wire or
disconnect electrical connections while these are live. Always disconnect the
power before working on the device. Dangerously high voltages of ≥50 V
may still be present 10 minutes after the power is cut (capacitor charging). So
always check that the power has been cut.
ATTENTION!
If local regulations require the installation of a residual current
operated protective device, the following applies: In case of a fault the drive
is able to generate d.c. leak currents without zero crossing. Drives therefore
must only be operated with (RCDs)
1)
type B for a.c. fault currents, pulsating
or smooth d.c. fault currents, which are suitable for servo drive operation, see
IEC 60755. RCMs
2)
can additionally be used for monitoring purposes.
1) Residual current protective device
2) Residual current monitor
Note the following points:
•
Switching the mains power:
− In case of too frequent switching the unit protects itself by high-resistance
isolation from the system. After a rest phase of a few minutes the device is
ready to start once again.
•
TN and TT network: Operation is permitted if:
− in the case of single-phase devices for 1 x 230 V AC the supply system
conforms to the maximum overvoltage category III as per EN 61800-5-1.
− in the case of three-phase devices with external conductor voltages
3 x 230 V AC, 3 x 400 V AC, 3 x 460 V AC and 3 x 480 V AC
1.
the neutral point
of the the supply system
is grounded
and
2. the supply system conforms to the maximum overvoltage category III
as per EN 61800-5-1 at a system voltage (external conductor
→
neutral
point) of maximum 277 V.
•
IT network:
not
permitted!
− In case of an ground fault the electrical stress is approx. twice as high.
Clearances and creepages to EN 61800-5-1 are no longer maintained.
!
•
Connection of the servo drives by way of a mains choke is mandatory:
− where the drive is used in applications with disturbance variables
corresponding to environment class 3, as per EN 61000-2-4 and above (hostile
industrial environment)
− in the case of single-phase mains supply
− for compliance with EN 61800-3 or IEC 61800-3
•
For further information on permissible current loads, technical data and ambient
conditions please refer to the appendix.
NOTE:
Please be aware that the MSD Servo Drive Compact is not rated
for environment class 3. Further measures are essential in order for that
environment class to be attained! For further information please consult your
project engineer.
