Items Explanations
Power supply Please follow the specific power supply requirements shown in ZD.3 Electrical
data– from page 143
Fuse/protective fuse
breaker (optional)
There may be an inrush current during power up. Please check the chart of ZD.5
Fuse protection– from page 146 and ZB.4 Fuses for device-protection– on page
132 to select the correct fuse. Use of an protective fuse breaker is optional.
Magnetic contactor
(optional)
Please do not use a magnetic contactor to switch on/off the b maXX

during device operation, as it will reduce the operating life cycle of the device.
Mains choke (optional) Used to improve the input power factor, to reduce harmonics and provide protec-
tion from mains interferences. (surges, switching spikes, short interruptions, etc.).
The mains choke should be installed when the power supply capacity is 500
kVA
or more and exceeds 6 times the device capacity, or the mains wiring distance
≤10 m. See Z6.15 Applications for mains chokes– on page 69 and ZB.3.1 Mains
chokes recommended values– on page 130 for further information.
Additional EMC filter
(optional)
To reduce electromagnetic interference.
NOTE
The models b maXX
®
1000 have an built-in EMI filter. An additional mains filter is
necessary for cable lengths > 15 m (cable device - motor).
For further information see ZB.2 Mains filters– on page 129.
Chopper unit/
braking resistor
(optional)
Used to reduce the deceleration time of the motor.
m Frame 1:
No built-in chopper unit:
Use of chopper unit and braking resistor necessary (refer to ZB.1.1 Select a
chopper unit /braking resistor– from page 120.
m Frame 2 and 3:
Built-in chopper unit:
Connection of a suitable braking resistor (see ZB.1.1 Select a chopper unit /
braking resistor– from page 120) possible.
If the motor generates additional regeneration energy a further chopper unit
with braking resistor can be connected.
Output choke (optional) Motor surge voltage amplitude depends on motor cable length.
For applications with long motor cable, it is necessary to install a choke at the
device output side.
230V 1-phase: 0,4 kW and smaller: max 15 m.
0,75 kW and higher: max 50 m.
400V 3-phase: 0,75 kW and smaller: max 20 m.
1,5 kW and higher: max 50 m.
For more information see ZB.3.2 Output chokes recommended values– on page
131.
