2Safety Instructions
2.1 Personnel and Qualifications
The inverter and the battery must only be installed, wired, connected, commissioned
and serviced by qualified personnel to prevent material damage or personal injury.
Qualified personnel authorised to perform the tasks described in this manual must have the following skills and technical
expertise:
They are trained to install electrical equipment.
They understand the technical functionality of an inverter
They are familiar with lithium iron phosphate (LiFeP04) accumulators.
They have read and understood the documents shipped with the unit.
They know and use the appropriate tools and equipment to perform the tasks described in the manual.
They are familiar with all current laws and applicable regulations, standards and directives for electrical equipment.
They are familiar with the safety requirements and guidelines for electrical equipment.
They are familiar with occupational health and safety regulations.
They know and use appropriate personal protective equipment.
Before starting installation or commissioning, read through the entire manual and note all DANGER! WARNING! CAUTION!
and NOTICE! statements.
2.2 Safety Procedures
The inverter was developed and tested in strict accordance with international safety regulations.
All safety instructions relating to electrical and electronic equipment must be complied with during installation, operation
and maintenance.
Danger to life or serious injury due to electric shock!
High voltages are present in cables and inner parts of the inverter if it is connected to the grid (AC /
AC voltage source) or the solar generator (DC / DC voltage source) is exposed to sunlight.
•Qualified personnel must perform any work that involves wiring, connecting or opening the
inverter case.
•Important: Both voltage sources (DC / solar generator and AC / grid) must be switched off
before any electrical work is carried out on the inverter.
•Turn the DC Switch into the 0 position to disconnect the DC voltage.
•Activate the circuit breaker or remove the fuse to disconnect the mains voltage (AC). Do
not reconnect until the work has been completed.
•To disconnect the battery voltage, both voltage sources (DC / solar generator and AC /
mains) must be switched off and the battery switch on the master must be set to "0".
•Allow a minimum of 10 minutes for the capacitors to fully discharge and then check the
voltage with a suitable measurement device.
•Ensure that other persons stay away from cables and internal components.

Risk of injury due to electric shock!
Installation, service and maintenance work must only be carried out by a qualified electrician.
•Do not drop the device. Do not expose it to knocks or pressure.
•Only switch on again after all electrical work has been completed.
Risk of burns on hot parts of the inverter housing.
During standard operation of the inverter, some parts of the inverter's housing can become hot.
•Use care when touching the housing while the inverter is operating.
•Do not cover the inverter (especially not the top).
•All electrical installations must be carried out in accordance with local and national
standards and guidelines.
•Contact your local energy supplier or grid operator before connecting the inverter to the
grid.
•Ensure that electrically conductive surfaces of the entire PV system are grounded to
prevent personal injury.
•A malfunction can impair inverter safety. Do not operate or start the inverter if it shows
visible damage or if the displayed error message is unclear.
•The inverter does not contain any parts to be serviced by the owner. Please contact
qualified personnel locally for servicing work on the inverter.
•Only use devices and accessories approved by the manufacturer. Do not make any changes
to the device. Do not remove the type plate.
