If the Inverter is to be installed at an altitude >1000m,
derating will be required. (Refer to DA64 Catalogue)
Do not drop the inverter or expose to sudden shock.
Do not install the inverter in an area where it is likely to
be exposed to constant vibration.
Do not install the inverter near sources of electro-
magnetic radiation.
Do not install the inverter in an environment, which
contains atmospheric pollutants such as dust,
corrosive gases, etc.
Take care to site the inverter away from potential
water hazards, e.g. do not install the inverter beneath
pipes that are subject to condensation. Avoid installing
the inverter where excessive humidity and
condensation may occur.
Mount the inverter vertically to ensure optimum
cooling. Additional ventilation may be required for
horizontal mounting.
Ensure that the inverter’s air vents are not obstructed,
including the air vent at the front of the unit, which
should be at least 15mm from any obstruction
Make sure that there is an adequate air-flow through
the cabinet, as follows:
1. Using the formula below, calculate the air-flow
required:
Air-flow (m3/ hr) = (Dissipated Watts / ∆T) x 3.1
2. If necessary, install cabinet cooling fan(s).
Note:
Dissipation (Watts) = 3-5% of inverter rating.
∆T = Allowable temperature rise within cabinet in °C.

1.2 Wiring Guidelines to Minimise the Effects of EMI
The inverters 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. Figure 1.2.1- 3 illustrates
how an RFI suppression filter should be installed.
(1) Ensure that all equipment in the cubicle is well earthed using short, thick earthing cable connected to a
common star point or busbar. It is particularly important that any control equipment that is 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. braids or metal brackets) are preferred as they have lower impedance
at high frequencies.
The return earth from motors controlled by the inverters should be connected directly to the earth
connection (PE) on the associated inverter.
(2) Wherever possible, use screened leads for connections to the control circuitry. Terminate the ends of
the cable neatly, ensuring that unscreened wires are as short as possible. Use cable glands whenever
possible.
(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° if possible.
(4) Ensure that contactors in the cubicle 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. This
is particularly important if the contactors are controlled from the relay on the inverter.
(5) Use screened or armoured cables for the motor connections and ground the screen at both ends via
the cable glands.
(6) If the drive is to be operated in an Electromagnetically noisy environment, the RFI filter should be
used to reduce the conducted and radiated interference from the inverter. For optimum performance,
there should be a good conductive bond between filter and metal mounting plate.
(7) For FSA units (Fig 1.2.1), the flat earth braid strap, supplied with the unit, should be fitted to minimise
emissions .
On no account must safety regulations be compromised when installing inverters!

1.3 Electrical Installation - General Notes
1.3.1 Operation with Unearthed (IT) Supplies
The MICROMASTER will operate from unearthed supplies and will continue to operate if an input phase is
shorted to earth. If an output phase is shorted to earth, the MICROMASTER will trip and indicate F002.
1.3.2 Operation with Residual Current Device (RCD)
The MICROMASTER inverters will operate without nuisance tripping with an RCD (also called ELCBs or
RCCBs) fitted to the input providing:
•A type B RCD is used.
•The trip limit of the RCD is 300mA.
•The neutral of the supply is earthed.
•Only one inverter is supplied from each RCD.
•The output cables are less than 50m (screened) or 100m (unscreened).
1.3.3 Installation after a Period of Storage
It is necessary to reform the capacitors in the inverter if the unit has been stored for a prolonged period.
•Period of storage 1 year old or less:
No reforming is required.
•1 - 2 years old:
Apply power to the inverter one hour before giving the run command. (Preparation time 1 Hour)
•2 - 3 years old:
Use a variable AC supply. Apply 25% of input voltage for 30 minutes. Increase volts to 50% for a further
30 minutes. Increase volts to 75% for further 30 minutes. Increase volts to 100% for a further 30 minutes.
Now ready for run signal. (Preparation Time 2 hours)
•3 years and over:
As with 2 - 3 years, but the steps should be 2 hours. (Preparation Time 8 Hours)
1.3.4 Operation with Long Cables
Motor cable lengths vary depending on type of cable, power rating and voltage rating - and in some cases can
be as long as 200m without the need for additional chokes. Refer to DA64 catalogue for further details.
In any case, all inverters will operate at full specification with cable lengths up to 25m for screened cable or
50m for unscreened cables.

2.2.5. External Motor Thermal Overload Protection
When operated below rated speed, the cooling effect of fans fitted to the motor shaft is reduced.
Consequentially, most motors require de-rating for continuous operation at low frequencies. To ensure that
motors are protected against overheating under these conditions, a PTC temperature sensor must be fitted to
the motor and connected to the inverter control terminals as shown in Figure 2.2.5.
Note: To enable the trip function, set parameter P051, P052 or P053 =19.

3.2 Basic Operation
Refer to section 5 for a full description of each parameter.
3.2.1 General
(1) The inverter does not have a main power switch and is live when the mains supply is connected. It waits,
with the output disabled, until the RUN button is pressed or for the presence of a digital ON signal at
terminal 5 (rotate right) or terminal 6 (rotate left) - see parameters P051 - P053.
(2) If output frequency is selected to be displayed (P001 = 0), the corresponding setpoint is displayed
approximately every 1.5 seconds while the inverter is stopped.
(3) The inverter is programmed at the factory for standard applications on Siemens four-pole standard motors.
When using other motors it is necessary to enter the specifications from the motor's rating plate into
parameters P081 to P085 (see Figure 3.2.1). Note: Access to these parameters is not possible unless
P009 has been set to 002 or 003.

Note: Ensure that the inverter is configured correctly to the motor, i.e. in the above example delta terminal
connection is for 220 V.
3.2.2 Initial Testing
(1) Check that all cables have been connected correctly (section 2) and that all relevant product and
plant/location safety precautions have been complied with.
(2) Apply mains power to the inverter.
(3) Ensure that it is safe to start the motor. Press the RUN button on the inverter. The display will change to 5.0 and
the motor shaft will begin to turn. It will take one second for the inverter to ramp up to 5 Hz.
(4) Press the STOP button. The display will change to 0.0 and the motor slow to a complete stop within one second.

3.2.3 Basic Operation - 10 Step Guide
The basic method of setting up the inverter for use is described below. This method uses a digital frequency
setpoint and requires only the minimum number of parameters to be changed from their default settings. It
assumes that a standard Siemens four-pole motor is connected to the inverter (see section 3.2.1 if a different
motor type is being used).
Step /Action Button Display
1. Apply mains power to the inverter.
The display will alternate between the actual frequency (0.0 Hz) and the
requested frequency setpoint (5.0 Hz default).
2. Press the parameterisation button.
3. Press the ∆button until parameter P005 is displayed.
4. Press P to display the current frequency setpoint (5 Hz is the factory
default setting).
5. Press the ∆button to set the desired frequency setpoint
(e.g. 35 Hz).
6. Press P to lock the setting into memory.
7, Press the ∇button to return to P000.
8. Press P to exit the parameterisation procedure.
The display will alternate between the current frequency and the requested
frequency setpoint.
9. Start the inverter by pressing the RUN button.
The motor shaft will start to turn and the display will show that the inverter is
ramping up to the setpoint of 35 Hz.
Note
The setpoint will be achieved after 7 seconds (35 Hz/50 Hz x 10 s *).
If required, the motor speed (i.e. frequency) can be varied directly by using
the ∆∇buttons. (Set P011 to 001 to enable the new frequency setting to be
retained in memory during periods when the inverter is not running.)
10. Switch the inverter off by pressing the STOP button.
The motor will slow down and come to a controlled stop (takes 7 s **).
*Default ramp-up time is 10 s to reach 50 Hz (defined by P002 and P013).
** Default ramp-down time is 10 s from 50 Hz (defined by P003 and P013).
