WARNINGS
 This equipment contains dangerous voltages and controls
potentially dangerous rotating mechanical parts. Non-compliance
with Warnings or failure to follow the instructions contained in this
manual can result in loss of life, severe personal injury or serious
damage to property.
 Only suitably qualified personnel should work on this equipment,
and only after becoming familiar with all safety notices,
installation, operation and maintenance procedures contained in
this manual. The successful and safe operation of this equipment
is dependent upon its proper handling, installation, operation and
maintenance.
 The DC link of all MICROMASTER modules remains at a
hazardous voltage level for 5 minutes after all voltages have been
disconnected. Therefore always wait for 5 minutes after
disconnecting the inverter from the power supply before carrying
out work on any MICROMASTER modules.
 This equipment is capable of providing internal motor overload
protection in accordance with UL508C. Refer to P0610 and
P0335. i2t is ON by default. Motor overload protection can also be
provided using an external PTC via a digital input.
 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 460 V when protected by an H, J or K type fuse, a
circuit breaker or self-protected combination motor controller.
 Class 1.75 °C copper wire only.
 See Operating Instructions for recommended tightening torques.
 If a Residual Current-operated protective Device (RCD) is to be
used, it must be an RCD Type B.
 COMBIMASTER 411 & MICROMASTER 411 cannot be used
on unearthed power supplies (IT).
CAUTION
 Children and the general public must be prevented from
accessing or approaching the equipment!
 This equipment may only be used for the purpose specified by the
manufacturer. Unauthorized modifications and the use of spare
parts and accessories that are not sold or recommended by the
manufacturer of the equipment can cause fires, electric shocks
and injuries.
NOTES
 Keep this Getting Started Guide within easy reach of the
equipment. Ensure that it is available to all users.
 Whenever measuring or testing has to be performed on live
equipment regulations of Safety Code VBG 4.0 must be observed,
in particular § 8 ‘Permissible Deviations when Working on Live
Parts’. Suitable electronic tools should be used.
 Before carrying out any Installation and Commissioning
procedures, you must read all safety instructions and warnings,
including all warning labels attached to the equipment. Make sure
that the warning labels are kept in a legible condition and ensure
missing or damaged labels are replaced.
 All measurements are in metric. To convert to inches use a
conversion factor of 0.039.
 Power values are given in kW. To convert from kW into hp use a
conversion factor of 1.34.

Prior to installation it may be necessary to fit an Adaptation Plate to a
non-Siemens motor. The Adaptation Plate is prepared by the
respective motor manufacturer. Normally the Adaptation Plate makes
use of the existing motor gasket.
Physical dimensions and characteristics for installation of
MICROMASTER 411 are given in Section 2.3.3 and in Section 2.4.2
for COMBIMASTER 411 of the Operating Instructions.

Getting Started Guide – 07/05
With the product items removed from their packaging carry out the
following installation procedure (refer to Figure 3 for location of
components):
1. Separate the two halves (Inverter Cover and Terminal Housing).
2. Remove the Filter Module and I/O board.
CAUTION
Do not knock out cable gland blanking plates unless the inverter
‘electronics’ (Filter & I/O boards) have been removed!
3. Remove the cable gland blanking plates (knockouts) as required.
See Figure 1.
4. Fit cable glands to terminal housing, ensuring the O-rings are fitted
to ensure the seal is maintained.
5. Fit the earth lead to the earth terminal within the motor terminal
box. If required fit a Motor PTC cable (not supplied).
6. Run all cables between the motor and inverter within the cable
sheath provided.
7. Using the appropriate motor gasket, fix the terminal housing to the
motor.
Screw fixing torque values are: 1.5 Nm – M4 and 2.5 Nm – M5.
8. Insert power and control cables through glands and make off ends
as required.
9. Fit the Filter Board (See Figure 3).
10. Secure Filter board with M3 taptite screws (0.8 Nm).
11. Connect power cables as detailed in Section 1.2.1.
12. Connect up the motor terminals in either star or delta configuration
as described in Section 1.2.2.
13. Connect control wires as described in Section 1.2.3.
14. Fit the I/O board (see Figure 3).
15. Secure I/O board with M3 taptite screws (0.8 Nm).
16. Fit jumpers as required (see Section 2.2.1 and 2.2.2).
17. Place the inverter cover onto the assembled terminal housing.
18. Secure the inverter cover with the four M5 captive screws.
Use either a 4-5 mm flat bladed screwdriver or a 2pt Pozidrive
Head screwdriver.

1.1.3 Installation of Cable Glands
WARNING
MICROMASTER 411/COMBIMASTER 411 is not suitable for
connection to rigid conduit systems. Use flexible cables (CY and SY
types) for motor output and flexible cables or flexible conduit for mains
input or control connections.
Before power and control cables can be connected to their respective
circuits it will first be necessary to fit the cable glands supplied.
Each gland should preferably be located to allow for convenient cable
runs to the terminals located on the Filter and I/O boards.
Using a hammer as
shown opposite strike
the gland plate or
‘knockout’ to obtain a
clearance for the 25
mm cable gland.
Remove any sharp
edges from the gland
area and any swarf
from the terminal
housing.
After the knockout has
been removed it
should be safely
discarded and the
cable glands fitted as
shown in the assembly
diagram opposite.

1.2 Electrical Installation
1.2.1 Power Cable Connections
1. If the Inverter cover (the top-half) has already been fitted unscrew
the four M5 cross-head captive screws on the inverter cover.
2. Remove inverter (cover) to access electrical terminals.
3. Feed the power cable into the terminal housing via the appropriate
gland hole.
4. Connect power leads to terminals L1, L2, L3 and to the separate
earth.
To avoid snagging on components when the inverter halves are
brought together run cables along the base of the terminal housing.
5. Use Class 1 75o C copper wire only. Use a 4-core cable. If crimp
terminals are used they must be insulated. If crimps are not used,
the strip length must not exceed 5 mm. Use a 4 - 5 mm cross-tip
screwdriver to tighten the terminal screws.
6. Recommended tightening torque for power supply terminals is as
given below.

7. A ‘drip loop’ is recommended when connecting the mains and
control cables.
8. Ensure that the power source provides the correct voltage and is
designed for the rated current. Use appropriate circuit breakers
with specified current rating between the power supply and
inverter.
9. Ensure the appropriate circuit breakers/fuses with the specified
current rating are connected between the power supply and the
inverter. See Section 7.5 of the Operating Instructions for further
details.

WARNINGS
 It is essential that the Inverter be correctly grounded to the motor
ground. Severe injury may result if the motor is not correctly
grounded.
 If the inverter is being installed after a period of storage please
refer to Section 2.1 of the Operating Instructions.
1.2.2 Motor Connections for Star/Delta
The following information shows the connection of the motor wires to
inverter/motor terminals. Motor wires should be connected in either
star or delta configuration, in accordance with the motor rating plate.

CAUTION
It is essential that control and power supply cables be run separately.
They must not be fed through the same cable conduit/trunking.
1. Feed the control cable into the inverter via one of the gland holes
at the I/O module end of the terminal housing.
2. Run the control cable underneath the I/O board toward the control
terminals.
3. Connect the control wires in accordance with the terminal
information given in Figure 6.
4. Use screened cable for all control wiring. Cable connections for
Control Terminals are as given in Figure 6.

2 Commissioning COMBIMASTER 411/
MICROMASTER 411
2.1 General Information
For default operation no additional equipment is required. However, for
more complex operation either the Basic Operator Panel (BOP),
Advanced Operator Panel (AOP) or Fieldbus options can be used.
These are available as non-standard options and must be ordered
separately.
When delivered the inverter has a frequency setpoint range of
between 0 Hz and 50 Hz. Regardless of its initial position the Control
Potentiometer must be turned fully counter-clockwise before the
inverter can start.
WARNING
The inverter does not have a mains power switch and is therefore live
when the power supply is connected.
