Safety Information
This manual contains important instructions that must be
followed during installation and maintenance of the
inverter.
Before Installation
Check the inverter and the packaging for damage.
If in doubt, contact the supplier before commencing
installation.
Installation/Service
For optimum safety, follow the steps described in this
document. Keep in mind that the inverter has two voltage
carrying sides: PV input and utility grid.
Disconnecting the inverter
Before working on the inverter, disconnect it from the utility
grid by means of the AC breaker and switch off DC using
the integrated DC load-break switch. Ensure that the
inverter cannot be unintentionally reconnected. Use a
voltage detector to ensure that the unit is disconnected
and voltage free. Wait at least five minutes after
disconnection from the utility grid and batteries before
proceeding.

Danger to life from electric shock due to live DC
cables
The DC cables connected to a battery may be live.
Touching the DC conductors or the live components leads
to lethal electric shocks.
• Do not touch non-insulated cable ends.
• Do not touch any live components.
• Have the inverter and the battery mounted, installed
and commissioned only by qualified persons with the
appropriate skills.
• Observe all safety information of the battery
manufacturer.
• Always disconnect the inverter and battery from
voltage sources before performing any work on
them.
• Wait five minutes before working on the inverter.
• If an error occurs, have it rectified by qualified
persons only.
