INSTALLATION
WARNING
Take note of the general and regional installation and safety regulations regarding
work on high voltage installations (e.g. VDE). Adhere to relevant regulations regarding
correct use of tools and protective gear.
Use the lifting eyes provided if a motor has to be lifted. Do not lift machine sets by
suspending the individual machines! Always check the capacity of the hoist before
lifting any equipment.
Do not paint over the black case finish of the inverter as this will affect the unit's
thermal performance.
General Wiring Guidelines
The Case Size A (CS A) and Case Size B
(CS B) COMBIMASTER and
MICROMASTER Integrated are designed to
operate in an industrial environment where a
high level of Electro-Magnetic Interference
(EMI) can be expected. Usually, good
installation practices will ensure safe and
trouble-free operation. However, if problems
are encountered, the following guidelines
may prove useful. In particular, grounding of
the system 0V at the inverter, as described
below, may prove effective.
1
All equipment must be well earthed using
short, thick earthing cable connected to a
common star point or busbar. It is
particularly important that any control
equipment connected to the inverter
(such as a PLC) is connected to the
same earth or star point as the inverter
via a short, thick link. Flat conductors
(e.g. metal brackets) are preferred as
they have lower impedance at high
frequencies.

WARNING
Take suitable precautions to prevent transmission elements from being touched. If the
COMBIMASTER is started up without a transmission element attached, the featherkey
must be secured in position to prevent it from flying off while the shaft is rotating.
Tighten down screw-in lifting eyes prior to
using the COMBIMASTER.
Stable foundations or mounting conditions
and a well balanced transmission element
are essential for quiet, vibration-free running.
It may be necessary to balance the whole
rotor and transmission element.

2
Use screened leads for connections to
the control circuitry. Terminate the ends
of the cable neatly, ensuring that long
strands of unscreened wire are not left
visible.
3
Separate the control cables from the
power connections as much as possible,
using separate trunking, etc. If control
and power cables cross, arrange the
cables so that they cross at 90
4
Ensure that contactors are suppressed,
either with R-C suppressors for AC
contactors or 'flywheel' diodes for DC
contactors, fitted to the coils. Varistor
suppressors are also effective.
Safety regulations must not be
compromised when installing the
COMBIMASTER or MICROMASTER
Integrated!
COMBIMASTER
The rotors are dynamically balanced with a
full featherkey inserted as standard. Since
1991 the type of balance has been marked
on the drive end of the shaft (shaft end face).
F denotes balanced with full featherkey; H
denotes balanced with half featherkey. Bear
in mind the type of balance used when fitting
the transmission element.
