Note the following points:
Switching the mains power:
y
In the event of excessively frequent switching the device protects itself by means of high-
resistance decoupling from the mains. After a rest phase of a few minutes the device is ready to
start once again.
TN and TT system: Operation is permitted if:
y
In the case of single-phase devices for 1 x 230 V AC the supply system conforms to th e
maximum overvoltage categor y III as per IEC/EN 61800-5-1.
y In the case of three-phase devices with phase conductor voltages 3 x 230 V AC, 3 x 400 V AC,
3 x 460 V AC and 3 x 480 V AC
y
The star point
of the supply system
is earthed
and
y
The supply system conforms to the maximum overvoltage category III as per IEC/EN 61800-5-1
at a system voltage (phase conductor
→
neutral point) of maximum 277 V .
IT system: Operation is
not
permitted!
y In case of an earth fault the voltage is approx. twice as high. Clearances and creepages to
IEC/EN 61800-5-1 are no longer maintained.
Connection of the servo drives via a mains choke is imperative:
y
Where the s ervo d rive is used in applications with disturbance variables corresponding to
environment class 3, as per IEC/EN 61000-2-4 and above (harsh industrial environment)
y In the case of single-phase mains supply
y
For compliance with IEC/EN 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 Single-Axis Servo Drive Compact is not
rated for environment class 3. Further measures are essential to achieve
this environment class! For further information please consult your project
engineer.
4.8.2 Connection of mains supply
Procedure:
Step Action Comment
1.
Specify the cable cross-section depending on the maxi-
mum current and ambient temperature.
Cable cross-section according to local
regulations and conditions.
2.
Wire the s ervo d rive with the mains filte *) , maximum cable
length 0.3 m (1.0 ft) (with non-shielded cable)!
3.
Wire the mains choke *)
(if installed)
Reduces the distortion (THD) in the system
and prolongs the life of the s ervo d rive.
4.
Install a mains isolating device K1
(power circuit breaker, contactor, etc.).
Do not switch on the power!
5.
Use mains fuses
(duty class gG) to isolate all poles of the s ervo d rive from
the mains supply.
For compliance with equipment safety
requirements laid down in IEC/EN 61800-
5-1

DANGER! Risk of injury due to electrical power!
•
Carelessness will result in serious injuries or death.
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 min.
after the power is cut (capacitor charge). So check that electrical power is not present!
CAUTION!
Risk or injury or damage to the device due to incorrect
earth leakage circuit breaker!
•
Carelessness may result in injuries or damage.
If local regulations require the installation of an earth leakage circuit breaker, the following
applies: In case of a fault the s ervo d rive is able to generate DC leakage currents without zero
crossing. Servo Drives therefore must only be operated with (RCDs) 1) type B for AC fault currents,
pulsating or smooth DC fault currents, which are suitable for s ervo d rive operation, see
IEC 60755. RCMs 2) can also be used for monitoring purposes.
