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.
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.
Electrical Installation | MICROMASTER Integrated
The motor wires should be connected in
either star or delta configuration on the MIP
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.
Ensure that the following tightening torques are used:
Access cover retaining screws4.0Nm
Gland hole covers:1.0Nm
Mains connector screws1.0Nm
PL700 Screws0.5Nm
Earth Connection 1.5Nm
Control Cable Connections
CAUTION
The control and power supply cables must be laid separately. They must not be fed
through the same cable conduit / trunking.
Use screened cable for the control lead.
Feed the control cable into the inverter via
the appropriate gland hole . Connect the
control wires in accordance with the
information in Figures 4,5 and 6 having first
unplugged connector block PL800 from the
PCB (CS B only).
IMPORTANT: A wire link must be fitted
between control terminals 5 (DIN1) and 1
(P10+) if it is required to start the inverter
from the control potentiometer R314, or the
analogue input. The wire link must be
removed when operation via a run/stop
switch is required.

The equipment must not be switched on until after its cover has been fitted and the
cover screws have been tightened to the correct torque (see Fig. 2 & 3).
After the power has been turned off, you must always wait five minutes so that the dc
link capacitors can discharge. Do not remove the cover until this time has elapsed.
All settings must be only entered by qualified personnel, paying particular attention to
the safety precautions and warnings.
General
For basic operation of COMBIMASTER, no
additional equipment is required. However,
for more complex operation, OPm2 – Clear
Text Display is required (OPm2 is available
as an option, but must be ordered
separately).
The inverter does not have a mains power
switch and is therefore live when the mains
supply is connected.
When delivered, the inverter has a frequency
setpoint range of between 0 Hz and 50 Hz.
Regardless of its initial position, internal
potentiometer R314 must be turned fully
counter-clockwise before it will start the
inverter.
R314 can be accessed by removing the
right-hand gland hole cover (see Fig. 2 & 3).
Analogue input type is selected by jumpers
JP300 and JP301. JP300 closed selects
current input, JP301 closed (default) selects
voltage input. These jumpers can only be
accessed when the cover is removed (seeFig. 2 & 3).
Basic Operation
If the motor is run unloaded (e.g. for test
purposes) and vibration or trip conditions
occur, change P077 from 0 to 3 (requires
OPm2).
There are two basic modes of operation for
the inverter.
1 Using the internal potentiometer only:
a For forward rotation, ensure that a link
is fitted between DIN1 (pin 5) and
P10+ (pin 1) on PL800/PL700 (seeFig. 4). For reverse rotation, connect
the link to DIN2 (pin 6) instead of
DIN1.
b Apply mains power. The green and
yellow LEDs will illuminate to show
that power is applied. Turn
potentiometer R314 fully counterclockwise, otherwise the
COMBIMASTER cannot be started.
c Turn the potentiometer clockwise until
the yellow LED extinguishes. This
indicates that power is now applied to
the motor. Continue turning clockwise
to increase the speed of the motor.
d Turn the potentiometer counter-
clockwise to reduce the speed of the
motor. Turning the potentiometer fully
counter-clockwise causes the motor to
slow to a complete stop. Check that
both LEDs are illuminated (STANDBY
mode).
2 Using a combination of the internal
potentiometer and a run/stop switch:
a Connect a run/stop switch between

between pins 5 and 1 before the run/stop
switch is fitted.
b Apply mains power. The green and

on/off switch to OFF. When the switch
is set to ON again, it will run at the
speed previously set using the
potentiometer.
1 Connect a 4.7 kΩ potentiometer to the
control terminals as shown in Fig. 4 or
apply a 0 - 10 V signal between pin 2
(0V) and pin 3 (AIN+). In both cases,
position jumper JP304 to connect 0V to
AIN-.
2 Ensure that a link is fitted between pin 5
(DIN1) and pin 1 (P10+).
3 Check that voltage input is selected by
ensuring that the jumper is fitted to
JP301.
4 Refit the cover, tighten the cover screws
to the correct torque and then apply
mains power to the inverter.
adjust the analogue control voltage) until
the desired frequency is achieved. The
unit will not switch on until a minimum of
2 V has been applied.
Note: The frequency set by the external
voltage is added to the frequency set by the
internal potentiometer.
As with Basic Operation (2), a run/stop
switch can be used to start and stop the
motor, or the direction of rotation can be
changed by connecting the link to DIN2
instead of DIN1.
Operation - Digital Control
This method of operation requires either a
Clear Text Display (OPm2) or a serial link
connection. For a basic startup configuration
using digital control, proceed as follows:
1 Remove the link that connects control
terminal 5 to terminal 1 (if one has been
fitted).
2 Connect control terminal 5 to terminal 1
via a simple on/off switch. This sets up
the inverter for clockwise rotation
(default). If counter-clockwise operation
is required, connect a switch between
control terminals 6 and 1.
3 Connect the OPm2 or serial link to
SK200. Refit the cover, tighten the cover
screws to the correct torque and then
apply mains power to the inverter.
4 Set parameter P006 to 000 to specify
digital setpoint.
5 Set parameter P005 to the desired
frequency setpoint.
6 Set the external on/off switch to ON or
press the ON button on the OPm2 (set
P007 = 001 to use the OPm2). The
inverter will now run at the frequency set
by P005.
Stopping the Motor
Via the external on/off switch: Setting the
switch to OFF overrides the setting on the
potentiometer and causes the motor to come
to a controlled stop.
Via the potentiometer: Turning the
potentiometer counter-clockwise until the
input voltage drops below 2 V causes the
motor to slow to a stop. . If an external
potentiometer is applied, the input voltage
must also be below 2V to stop.
If the Motor Does Not Start Up
Check the LEDs on the side of the inverter:
LED StateCOMBIMASTER / MICROMASTER Integrated Status

ONONMains power on, inverter not running (STANDBY)
ONOFFInverter running, as per control commands (ON)
Switch off, disconnect and then reconnect
the power, and then switch on again. Switch
off if the fault condition persists. Trips can be
reset by using DIN3.
If a warning occurs:
Switch off, disconnect and reconnect the
power and then switch on again.
If the fault/warning persists, further
investigation requires an OPm2 or a serial
link connection.
