General safety instructions

DANGER
High electrocution
Potentially fatal voltage is applied to
the solar inverter during operation. This
potentially fatal voltage is still present
for 10 seconds after all power sources
have been disconnected.
► Always disconnect the inverter from
power before installation, open the
AC/DC isolating switch and make
sure neither can be accidentally
reconnected.
► Only the cover from the fuse section
may be removed. Never open other
parts of the inverter.
► Wait at least 10 seconds until the
capacitors have discharged.
DANGER
High electrocution
Potentially fatal voltage may be ap-
plied to the DC connections of the solar
inverter. When light is falling on solar
modules, they immediately start pro-
ducing 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 can-
not be accidentally touched.
WARNING
High electrocution
When you remove the cover from the
fuse section, protection degree is no
longer IP65.
► Remove the cover only when it is
really necessary.
► Do not remove the cover when it is
raining and the inverter is wet.
► Close the cover tightly after work.
Installation and Operation Manual for RPI M50A
2. General safety instructions
● 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 operat-
ing instructions in this manual. For this reason, be
sure to observe and follow all instructions!
● Installation and commissioning may only be per-
formed by qualified electricians using the installa-
tion and commissioning 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 manu-
facturer 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 powered 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 during 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 three people.
● Only devices in compliance with SELV
(EN 69050) may be connected to the RS485 and
USB interfaces.
● All connections must be sufficiently insulated in
order to comply with the IP65 protection rating.
Unused connections must be closed by placing
cover caps on the solar inverter.
