1. Safety
1.1 Storing the operating instructions
IMPORTANT SAFETY INSTRUCTIONS
ØSAVE THESE INSTRUCTIONS.
These operating instructions contain safety notices that must be
observed during installation and maintenance. Therefore, keep
the operating instructions in a safe place for the entire life cycle
of the device.
Include the operating instructions if you sell the device or set it
up at another location.
1.2 Warning signs
Certain activities can cause danger during operation. Corre-
sponding warning signs concerning the dangers should precede
instructions concerning the activities. Danger signs are located
on the device.
A warning sign contains signal words which are explained in the
following table:
Signal word Description
DANGER Indicates a major danger. If it is not avoided,
serious injuries or death will result.
WARNING Indicates a dangerous situation. If it is not
avoided, it may lead to serious injuries.
CAUTION Indicates a potentially dangerous situation. If it
is not avoided, injuries may occur.
NOTICE If such a situation is ignored, material damage
may result.

CAUTION

1.3 Using the device
The device is a bidirectional inverter. It is used for charging a
DC link from a three-phase grid and for feeding the grid from
the DC link's energy.
■The power and the energy flow direction are adjustable.
■The device draws sinusoidal current from the mains or deliv-
ers sinusoidal current to the mains. The power factor cosφ
is adjustable.
■The DC link voltage is balanced to earth.
Any use not listed under "Typical fields of application" contra-
venes the intended purpose. TRUMPF is not liable for any ensu-
ing damages, in particular for property damage, personal injury
and loss of production. The operator bears all risks. The war-
ranty is rendered null and void.
Impermissible uses include, for example:
■Use of incorrect components.
■Operation on mains voltage outside the specification.
■Faulty installation (e.g., cables reversed).
■Use in unauthorized installation position.
■Misuse by untrained personnel.
■Use in unsuitable environmental conditions:
− Condensation, icing.
− Conductive soiling.
− Corrosive conditions (e.g. battery fumes, salt spray).
− Voltages outside of overvoltage category III (max. 4 kV
impulse withstand voltage).
− Operation at more than 2000 m above sea level.
− Outdoors.
− Failure to observe pollution degree 2 environmental con-
dition.
− In an explosive environment.
1.4 Authorized personnel
Installation, operation, configuration and maintenance work may
only be performed by authorized, trained and instructed person-
nel.
Authorized persons must be trained and be familiar with the
standards and regulations relevant to their tasks.
It is the duty and responsibility of the operator to maintain the
qualifications of the authorized personnel. The authorized per-
sonnel must therefore be trained at regular intervals.

Impermissible uses

The following activities may only be performed by authorized per-
sons:
■Setting up the AC-DC module.
■Connecting the AC-DC module.
■Commissioning the AC-DC module.
■Dismantling the AC-DC module.
■Operating the AC-DC module.
1.5 Warning signs on the AC-DC module
1 Read operating instructions 3 Dangerous residual voltage 5 Danger due to contact current
2 Dangerous voltage 4 Danger due to the weight of
the device
6 Risk of destruction: use string
optimizers.

1.7 Dangers from high voltages
Life threatening voltage!
The voltages present at the AC-DC module are life-
threatening.
ØOnly have work on the AC-DC module performed by author-
ized, trained and instructed personnel.
A67-0141-00.BKen-0

2022-03-23 Safety 7
WARNING

The AC-DC module produces voltages that can endanger
human life and health. These voltages occur both in the AC-DC
module as well as at the outputs of the AC-DC module.
The AC-DC module's connection cables carry voltages that are
life-threatening.
A person who comes into contact with live AC-DC module parts
may be killed or severely injured.
Simultaneous control via web-based user interface and
Modbus is possible!
Power transmission stopped using the user interface can
be started again and reversed via Modbus.
ØBefore carrying out work on the device, deenergize all sup-
ply lines and secure against reenergizing.
ØMake sure that the device is controlled via one channel
only (user interface or Modbus).
Protective measures taken by the
manufacturer
The AC-DC module is installed in an enclosed metal casing.
1.8 What you must know as an operator
1. The AC-DC module must not be opened.
There are no parts within the device that can be serviced by
the user.
2. Only operate the AC-DC module within the conditions descri-
bed in chapter "Technical specifications".
3. Only operating personnel without pacemaker or implants
may work in the operational site.
4. For the electrical connection, use only cables that are in per-
fect condition and have the correct dimensions.
5. Periodically retest acc. to DGUV regulation 3 (DGUV = Deut-
sche Gesetzliche Unfallversicherung – German Statutory
Accident Insurance Association).
