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 15 seconds after all

power sources have been disconnected.

ŹNever open the solar inverter.

ŹAlways disconnect the solar inverter from

power before installation, open the DC

disconnection switch and make sure neither

can be accidentally reconnected.

ŹWait 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.

ŹNever disconnect the solar modules when the

solar inverter is powered.

ŹFirst switch off the grid connection so that

the solar inverter cannot feed energy into the

grid.

ŹTurn the DC disconnection switch to position

OFF.

ŹMake sure the DC connections cannot be

accidentally touched.

ƔRead this quick installation guide before you start installing

the inverter.

ƔThe 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!

ƔInstallation and commissioning may only be performed by

TXDOL¿HGHOHFWULFLDQVXVLQJWKHLQVWDOODWLRQDQGFRPPLVVLRQ-

ing instructions found in this manual.

ƔThe solar inverter must be disconnected from power and the

solar modules before any work on it can be performed.

ƔThe solar inverter has a high leakage current value. The

ground wire must be connected before commissioning.

ƔDo not remove any warning signs that the manufacturer has

installed on the solar inverter.

ƔImproper 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.

ƔThe 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.

ƔDo not disconnect any cables when the solar inverter is pow-

ered due to risk of a fault arc.

ƔTo prevent lightning strikes, follow the relevant regulations

applicable in your country.

ƔThe surface of the solar inverter can become very hot dur-

ing operation. Use safety gloves when working on the solar

inverter.

ƔOnly devices in compliance with SELV (EN 69050) may be

connected to the RS485 interfaces.

Risk of death by electrocution

Potentially fatal voltage is present when the solar inverter is in operation that remains for 15 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.

The housing of the inverter must be grounded if this is required by local regulations.

ŹDo not install inverters directly above one another.

Otherwise, the upper inverter is warmed up by the

lower one.

ŹConsider the operating temperature range (see sec-

When the operating temperature range is exceeded,

the solar inverter reduces the amount of power gener-

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.

Minimum tripping current of the RCD 30 mA *

Table: Recommended RCD Type A for one inverter

* see description in the note below

The value of the tripping current mainly depends

on the installation of the PV generator, the size of

the PV array and environmental conditions (e.g.

humidity).

Risk of death or serious injury from electrocution

Potentially fatal voltage may be applied 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 directly onto the

solar modules.

ŹTurn the DC disconnection switch to position OFF.

ŹNever disconnect the solar modules when the solar inverter is powered.

Connecting digital inputs and dry contacts (optional)

When your grid operator wants you to set a power

limitation, e.g. for the 70% regulation in Germany, you

need the Delta Service Software, which is available

from Delta.

If you need to wire dry contacts, digital inputs or RS485,

it is recommended to do this in a dry environment and

before you hang the inverter onto the wall. Reasons for

this are:

ŹYou will have to remove the covers from the

connection ports. Water could leak into the inverter.

ŹThe terminal blocks inside are not easily accessible.

VCC can be used for an external relais.

For connecting RS485, Pins 3 to 6 are used.

If you want to use SOLIVIA Monitor, the Internet based monitor-

ing from Delta, you will also need a SOLIVIA M1 G2 Gateway.

Default baud rate is 19200 which can be changed on the inverter
