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
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 main switch 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.

INFORMATION
The PV load-break switch can be secured in the "Off"
position using a padlock.
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. If
non-original spare parts are used, compliance with CE/UL
guidelines in respect of electrical safety, EMC and
machine safety is not guaranteed.
INSTALLER
Observe the National Electric Code, ANSI/NFPA 70.
Input and output circuits are isolated from the enclosure.
System grounding is the responsibility of the installer.
RISK OF ELECTRIC SHOCK
These maintenance instructions are 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 user manual unless you are qualified
to do so.
The inverter is not equipped with a transformer and is
intended to be installed according to NFPA 70, 690.35
with an ungrounded (floating) PV array.
Input and output circuits are isolated from the enclosure.
System grounding, if required by the Canadian Electrical
Code, Part I, is the responsibility of the installer.
