SAFETY AND CE COMPLIANCE
Before installing and operating this equipment read these safety instructions and warnings
carefully. Also read and obey all the warning signs attached to the equipment. Make sure that
the warning labels are kept in a legible condition and replace any missing or damaged labels.
WARNING
This equipment must be installed, operated and maintained by suitably qualified
personnel only.
Use only permanently-wired input power connections. The equipment must be
grounded (IEC 536 Class 1, NEC and other applicable standards).
Wait at least five minutes after the power has been turned off, before opening the
equipment. The dc-link capacitor remains charged to dangerous voltages even when
the power is removed. When working on open equipment, note that live parts are
exposed and do not touch these parts.
Some parameter settings can start the motor automatically when power is restored
after a mains failure.
Do not connect machines with a three-phase power supply, fitted with EMC filters, to a
supply via an ELCB (Earth Leakage Circuit Breaker - see EN50178, section 6.5).
Obey all general and regional installation and safety regulations relating to work on
high voltage installations, as well as regulations covering correct use of tools and
personal protective equipment.
Note that the following terminals can carry dangerous voltages even when the inverter
is inoperative:
Power supply terminals L1, L2 and L3
Motor terminals U, V and W
When using the analogue input, the jumpers must be correctly set and the analogue
input type selected (P023) before enabling the analogue input with P006. If this is not
done the motor may start inadvertently.
This equipment is capable of providing internal motor overload protection in
accordance with UL508C section 42.
This equipment is suitable for use in a circuit capable of delivering not more than
10,000 symmetrical amperes (rms), for a maximum voltage of 230V/480V/500V when
protected by a time delay fuse (see Electrical Data for details).
Do not operate the equipment in direct sunlight.
This equipment must not be used as an ‘emergency stop’ mechanism (see EN 60204,
9.2.5.4).
CAUTION
Do not allow children or the general public to access or approach this equipment.
High voltage insulation test equipment must not be used on cables connected to the
equipment.
Keep operating instructions within easy reach and give them to all users.
Use this equipment only for the purpose specified by the manufacturer. Do not carry
out any modifications, or fit any spare parts which are not sold or recommended by the
manufacturer; this could cause fires, electric shock or other injuries.

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.
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!
Mechanical Installation | COMBIMASTER
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.
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.
o
.
4 © Siemens plc1999 | G85139-H1731-U400-D2
Poor running characteristics can arise in
cases where the transmission elements have
a length ratio of hub length to shaft end
length < 0.8 and they run at speeds greater
than 1500 rpm. In such cases rebalancing
may be necessary, e.g. by reducing the
distance by which the featherkey protrudes
from the transmission element and the shaft
surface.
Please check the following prior to
commissioning:
• The rotor turns freely without rubbing.
• The motor is assembled and aligned
properly.
• The transmission elements are adjusted
correctly (e.g. belt tension) and the
transmission element is suitable for the
given operating conditions.
• All electrical connections, mounting
screws and connecting elements are
tightened and fitted correctly.
• All protective conductors are installed
properly.
• Any auxiliary equipment that might be
fitted (e.g. mechanical brake) is in
working order.
• Protection guards are installed around all
moving and live parts.
• The maximum speed (see motor rating
plate) is not exceeded. The maximum
speed is the highest operating speed
permitted. Remember that motor noise
and vibration are worse at this speed
and bearing life is reduced.
The above list is not meant to be exhaustive
- additional checks may also be required.
Mechanical Installation | MICROMASTER Integrated
The motor / MICROMASTER Integrated
combination should be installed according to
guidelines similar to those given above for
the COMBIMASTER.
First fit the Motor Interface Plate (MIP) to the
motor. In most cases the MIP makes use of
the existing motor gasket. Refer to Siemens
Document ‘MMI Motor Adaptation
Guidelines’ (English) – (Available 2
1999.– G85139-H1731-U500-A1.

WARNING
It is essential that the MIP is correctly earthed to the motor. This is usually achieved
using a short earth cable connected between the MIP and a suitable connection point
on the motor. Death or severe injury can result if the motor is not correctly earthed.
Incorrect earthing can also prevent any MICROMASTER Integrated built-in EMC filter
from operating correctly.
Electrical Installation | COMBIMASTER and
MICROMASTER Integrated
Remove the four M5 cross-head screws on
the inverter's cover to access the electrical
terminals (see Figs 2 and 3).
Notes: Refer to the Electrical Data tables for
cable sizes.
CAUTION
The printed circuit boards contain CMOS components that are particularly sensitive to
static electricity. For this reason, avoid touching the boards or components with hands
or metal objects.
Mains Cable Connections
Ensure that the power source supplies the
correct voltage and is designed for the rated
current. Use the appropriate circuit-breakers
with the specified current rating between the
power supply and inverter.
Use Class 1 60/75
4-core screened cable. If crimp terminals are
used they must be insulated. If crimps are
not used, the strip length must not exceed
5mm.
o
C copper wire only. Use a
A ‘drip loop’ is recommended when
connecting the mains and control cables
(see Fig. 6).
Feed the power cable into the inverter via the
gland hole nearest to the motor shaft.
Connect the power leads to terminals L1, L2,
L3 (L1, L2 for single phase units) and the
separate earth.
Use a 4 - 5 mm cross-tip screwdriver to
tighten the terminal screws.
