General safety instructions

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 60 seconds after all
power sources have been disconnected.
Never open the solar inverter.
Always disconnect the solar inverter from
power before installation, open the AC/DC
isolating switch and make sure neither can
be accidentally reconnected.
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.
Never disconnect the solar modules when the
solar inverter is powered.
First switch off the grid connection so that
the solar inverter cannot feed energy into the
grid.
Turn the AC/DC isolating switch to position
OFF.
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!
Installation and commissioning may only be performed by
-
ing instructions found in this manual.
The solar inverter must be disconnected from power and the
solar modules before any work on it can be performed.
The solar inverter has a high leakage current value. The
ground wire must be connected before commissioning.
Do not remove any warning signs that the manufacturer has
installed on the solar inverter.
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.
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.
Do not disconnect any cables when the solar inverter is pow-
ered due to risk of a fault arc.
To prevent lightning strikes, follow the relevant regulations
applicable in your country.
The surface of the solar inverter can become very hot dur-
ing operation. Use safety gloves when working on the solar
inverter.
The solar inverter is very heavy. The solar inverter must be
lifted and carried by at least two people.
Only devices in compliance with SELV (EN 60950) may be
connected to the RS485 and USB interfaces.
-
ply with the IP65 protection rating. Unused connections must
be closed by placing cover caps on the solar inverter.

60 seconds
Risk of death by electrocution
Potentially fatal voltage is present when the solar inverter is in operation that remains for 60 seconds after being
disconnected from power.
Never open the solar inverter. The solar inverter contains no components that must be maintained or repaired by
the operator or installer. Opening the cover will void the warranty.
Read the manual delivered with the inverter before working with the solar inverter and follow the instructions
contained in the manual.
Risk of injury from hot surfaces.
When in operation, the housing of the solar inverter can become very hot.
The housing of the inverter must be grounded if this is required by local regulations.
Regulatory Compliance Mark (RCM mark): The inverter is compliant with the Australian Electrical Safety and
EMC standards. Applies only to Australia and New Zealand.

Do not install inverters directly above one another.
Otherwise, the upper inverter is warmed up by the
lower one.
Consider the operating temperature range (see
“Technical data”, p. 18).
When the operating temperature range is exceeded,
the solar inverter reduces the amount of power gener-
ated.

Outdoor installations
The solar inverter has protection

Always use the mounting plate
supplied with the inverter.
Check that the wall is capable of
bearing the heavy weight of the
inverter.
Use dowels and screws that are
suitable for the wall material and

vibrations.
Possible noise emissions can be
disruptive when the inverter is
used in living areas or in buildings

The inverter is not capable of feeding in DC residual currents due
VDE 0100-712.
The possibilities of faults were examined by Delta without tak-
ing the integrated RCMU (residual-current monitoring unit) into
account. When examining these faults in terms of the current
valid installation standards, no danger in combination with a type
A upstream residual-current device (RCD) can occur. Therefore
faults that would otherwise require the use of a type B residual-
current device due to the inverter can be excluded.
The integrated all-pole sensitive RCMU provides additional
safety. RCD Type A can be used for this inverter, according to the
following table.
M6A M8A M10A
Minimum tripping current of the
RCD mA 100 100 100
NOTE
The value of the tripping current mainly depends
on the quality of the solar modules, the size of
the PV array and environmental conditions (e.g.
humidity).
