General Safety
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, the PV input and the 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 PV using
the integrated PV load-break switch (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. The inverter can still
be charged with very high voltage at hazardous levels
even when it is disconnected from utility grid and PV
modules. Wait at least five minutes after disconnection
from the utility grid and PV modules before proceeding.

DC voltages up to 1000 V are present in a PV system
even when the inverter is disconnected from the utility grid.
Faults or inappropriate use may lead to electric arcing.
MAINTENANCE AND MODIFICATION
Only authorized personnel are permitted to repair or
modify the inverter. To ensure personal safety, use only
original spare parts available from the supplier.
INSTALLER
Input and output circuits are isolated from the enclosure.
System grounding is the responsibility of the installer.
RISK OF ELECTRIC SHOCK
This manual is intended for use by qualified personnel
only. To reduce the risk of electric shock, do not perform
any maintenance work other than that specified in the
manual unless you are qualified to do so.
A
INFORMATION
The PV load-break switch can be secured in the "Off"
position using a padlock.
INFORMATION
Only for SHP 75-10:
The inverter is not intended to be used in living areas
and cannot provide protection of radio reception
against interference signals in such environments.
In accordance with EN55011:2016, the inverter
must only be operated at operation locations where
the distance between the inverter and
radio-communication installations is greater than
30 m and an own power transformer is used.
