All components of the application (frequency inverter, drive, power supply and its fuse
protection) must be coordinated with each other regarding their rated variables, their
function, and all parameter settings.
Modification or manipulation of the MVH2.0 is not permitted.
Modification or tampering with the MVH2.0 means that the product is being used outside
of its specification and is therefore a non-intended use, which can cause personal injury
and damage to the system. Any consequences of improper use of the product are not
covered by AuCom Support and will void the guarantee or warranty. AuCom excludes all
liability for improper use and any consequences that may arise from it.
Any use that does not correspond to the intended use of the MVH2.0 productis considered
misuse.
DANGER
Danger in case of misuse
Misuse of the MVH2.0 can result in death, serious personal injury, and
damage to the equipment.
➢Never operatethe productunless allsafety devicesof the MVH2.0
are functioning properly or are ready for operation.
➢Never operate the product at a voltage level that does not
correspond to the specified VFD input voltage.
➢Never connect drives to the product whose rated voltage and
current are not matched to the rated values of the MVH2.0.
➢Never put the product into operation unless all parameter
settings of the MVH2.0 have been adjusted to the connected drive
and the application.
➢Never modify or manipulate the product with hardware and/or
software components not specified by AuCom.
➢Never use spare parts that are not specified by AuCom.
1.3 TARGET AUDIENCE AND QUALIFICATION
The MVH2.0 Series frequency inverters are intended for use by qualified personnel in
commercial areas of various industries where frequency inverters are used to control the
speed of three-phase medium voltage motors.
This user manual is intended for qualified personnel for the commissioning, operation,
and maintenance of this product. According to their training and experience, qualified
personnel are able to recognise risks when using the product and its applications and to
avert potential hazards to persons and system components.
For commissioning and operation, the product offers four different user levels, each
adapted to different tasks. Each level requires different qualifications and authorisation.
At this user level, the technical personnel have basic technical knowledge for applications
of frequency inverters on the medium voltage level. This user level allows the start/stop
control of MV AC motors via the frequency inverter.
This user level does not require a password to operate the drive. Instructions for the
operating personnel are given in this user manual.
The technical personnel have advanced expertise for applications of frequency inverters
on the mediumvoltage level. This user level allows start/stop control of MV AC motors via

1.4 SAFETY INSTRUCTIONS
1.4.1 FIVE SAFETY RULES OF ELECTRICAL ENGINEERING
For all work on the MVH2.0 you must apply the five safety rules of electrical engineering
according to DIN VDE 0105 in the following order:
1. Switch off
2. Lock against reclosure
3. Check that lines and equipment are dead
4. Ground and short circuit all phases
5. Cover, partition, or screen adjacent line sections
To restart the equipment, follow the five safety rules is done in reverse order.
1.4.2 SAFE OPERATION
WARNING
➢Do not use the VFD if there is moisture in the VFD cabinet, parts
are missing, or parts were damaged during unpacking.
➢If the packing list does not correspond to the model number
indicated on the nameplate you must not install the VFD.
➢When transporting or lifting the VFD, make sure that the means
of transport is suitable for the weight and dimensions of the VFD.
If this is not the case, the VFD may be damaged during handling.
CAUTION
➢Follow the instructions in this manual. Installation must only be
carried out by qualified personnel.
➢Install the VFD only on suitable surfaces (metal or concrete) and
away from combustible materials to avoid fire hazard.
➢Do not touch the electronic components inside the VFD cabinet
directly during installation as this may cause electrostatic
damage to the VFD.

SAFETY
MVH2.0 USER MANUAL MVH2.0_BA_1.0.0_en 14/254
➢Only install or remove PCBs und ESD-compliant conditions
(antistatic protection).
➢Tighten screws and other parts according to the specified
torques.
➢Make sure that no metal chips, wire debris and other small parts
can enter the VFD cabinet to prevent damage to the VFD during
operation.
WARNING
➢Never connect the phases of the medium voltage (L1, L2, L3) to
the VFD output terminals (2U, 2V, 2W).
➢Electrical connections must only be made by qualified personnel
and in accordance with the relevant standards for electrical work.
➢Make sure that all power supplies and auxiliary voltages are
switched off before wiring to avoid electric shock or fire.
➢Ground the VFD cabinet properly to avoid electrostatic charges.
WARNING
➢Before applying mains supply voltage, make sure that the supply
voltage corresponds to the rated voltage of the VFD.
➢Make sure thatthe main circuit wiringis correctly connected, and
terminal screws are tightened with the specified torques.
➢The VFD must not be energised until the wiring is completed and
the cabinet doors are closed. Never open acabinet door when the
medium voltage supply is switched on to avoid the risk of electric
shock.
➢If automatic start after MV loss is enabled, you must take
appropriate safety precautions in the periphery of the VFD to
prevent personnel injury and damage to the property.
➢As soon as the VFD is switched on, the terminals of the VFD are
live. This also applies to stop mode. Do not touch the terminals as
this may cause an electric shock.
➢Do not disconnect the power supply for the fans while the VFD is
in operation as this may cause overheating and damage to the
VFD system. This will also cause the control system to shut down.
➢For water-cooled VFDs, the cooling water supplied by the
customer must meet the specifications.
➢Do not reset a fault message until it the start command has been
disabled. Resetting fault messages when the start command is
active can lead to personal injury and damage to the equipment.

WARNING
➢Make sure that the VFD output is isolated and earthed before
starting any work on the VFD.
➢If the load can remain in operation while the VFD is being
serviced, you must isolate the VFD from the motor to avoid
electrical shock.
➢Never troubleshoot or service the VFD with the medium voltage
switchedon.YoumustswitchofftheVFDbeforeopeningacabinet

➢To avoid injuries from the residual voltage of the main circuit
capacitors, wait at least 10min after disconnection or failure of
thepower supplyandmake surethatthevoltageindicatorson the
power cells are off before carrying out maintenance and
inspection work.
➢Only qualified personnel can perform maintenance, inspection,
and repair work.
CAUTION
Dispose of all used components or parts properly.
