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 ve minutes after all power sources
have been disconnected.
► Never open the solar inverter.
► Always disconnect the solar inverter from power before installation, open
the DC isolating switch and make sure neither can be accidentally recon-
nected.
► Wait at least ve minutes until the capacitors have discharged.
DANGER
Risk of death or serious injury from electrocution
Potentially fatal voltage may be applied to the DC connections of the solar
inverter.
► Never disconnect the PV modules when the solar inverter is powered.
► First switch off the grid connection so that the solar inverter cannot feed
energy into the grid.
► Then open the DC isolating switch.
► 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 operating instructions in this manual. For
this reason, be sure to observe and follow all instructions!
● Installation and commissioning may only be performed by qualied electricians using the
installation and commissioning instructions found in this manual.
● The solar inverter must be disconnected from power and the PV 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 my 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 opera-
tor 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.
