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Clearances and creepages to EN61800-5-1 are no longer maintained.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.
