General Safety Instructions
1
DANGER
Risk of death by electrocution
Potentially fatal voltage is applied to the solar
inverter during operation. This potentially fatal
voltage is still present for 15 seconds after all
power sources have been disconnected.
Ź
Never open the solar inverter.
Ź
Always disconnect the solar inverter from
power before installation, open the DC
disconnection switch and make sure neither
can be accidentally reconnected.
Ź
Wait at least 60 seconds until the capacitors
have discharged.
DANGER
Risk of death or serious injury from elec-
trocution
Potentially fatal voltage may be applied to the
DC connections of the solar inverter. When light
is falling on solar modules, they immediately start
producing energy. They do so, even when the
sun is not shining.
Ź
Never disconnect the solar modules when the
solar inverter is powered.
Ź
First switch off the grid connection so that
the solar inverter cannot feed energy into the
grid.
Ź
Turn the DC disconnection switch to position
OFF
.
Ź
Make sure the DC connections cannot be
accidentally touched.

The solar inverter can be safely and normally operated if
installed and used in accordance with this manual (see
IEC 62109-5.3.3). Delta Energy Systems is not responsible
for damage incurred by failure to observe the installation and
commissioning instructions in this manual. For this reason,
be sure to observe and follow all instructions!
Ɣ
Installation and commissioning may only be performed by

-
ing instructions found in this manual.
Ɣ
The solar inverter must be disconnected from power and the
solar modules before any work on it can be performed.
Ɣ
The solar inverter has a high leakage current value. The
ground wire
must
be connected before commissioning.
Ɣ
Do not remove any warning signs that the manufacturer has
installed on the solar inverter.
Ɣ
Improper handling of the solar inverter may result in physical
injury and damage to property. For this reason, observe and
follow all general safety instructions and warnings.
Ɣ
The solar inverter contains no components that must be
maintained or repaired by the operator or installer. All repairs
must be performed by Delta Energy Systems. Opening the
cover will void the warranty.
Ɣ
Do not disconnect any cables when the solar inverter is pow-
ered due to risk of a fault arc.
Ɣ
To prevent lightning strikes, follow the relevant regulations
applicable in your country.
Ɣ
The surface of the solar inverter can become very hot dur-
ing operation. Use safety gloves when working on the solar
inverter.
Ɣ
Only devices in compliance with SELV (EN 69050) may be
connected to the RS485 interfaces.
