► Never disconnect the inverter from the solar

modules when it is under load.

► Disconnect the connection to the mains so

that the inverter cannot supply energy to the mains.

► Disconnect the inverter from all AC and DC

voltage sources. Ensure that none of the connections can be restored accidentally.

► Ensure that the DC cables cannot be

touched accidentally.

Planning the installation

Installation location of the inverter

► Attach the inverter so that the information on the display

can be read and the buttons can be operated without any problems.

✔

✘ ✘

► The inverter is very heavy. The wall

or mounting system must be able to bear the heavy weight of the inverter.

► Always use the mounting plate

supplied with the inverter.

► Use mounting materials (dowels,

screws etc.) that are suitable for the wall or the mounting system, as well as the heavy weight of the inverter.

► Mount the inverter on a vibration-

free wall to avoid disruptions.

► When using the inverter in residenti-

al areas or in buildings with animals, possible noise emissions can be disturbing. Therefore, carefully choose the place of installation.

► Mount the inverter on a reproof

wall.

Mounting alignment

Outdoor installations

► The inverter has a protection degree of IP65 and can be

installed indoors and outdoors. Despite this, the inverter should be protected by a roof against direct solar irradiation, rain and snow. For example, the power of the inverter will be reduced if it is too heavily heated by solar radiation. This is normal operating behavior for the inverter and is necessary to protect the internal electronics.

Planning the installation

► Ensure sufcient air circulation. Hot air

must be able to dissipate upwards. Leave enough space around each inverter.

► Do not install inverters above one ano-

ther so that they do not heat each other.

► Note the Operating temperature ran-

ge without derating and the Operating temperature range. When the Operating temperature range without derating is

Special instructions for the use of aluminum cables

The instructions contained in this section refer

specically to the use of aluminum cables with

this inverter. These instructions supplement the specications of the manufacturer of the terminal blocks.

Handling aluminum conductors during installation work

The special properties of aluminum must be taken in to consideration when using aluminum:

● Aluminum "ows", i.e. it gives way under pressure.

● A thin non-conductive oxide layer forms within a few minu- tes on de-insulation, which increases the contact resistance between the conductor and clamping point.

● The specic conductivity and hence the current carrying capacity is approximately one third less than that of copper.

ATTENTION

Extreme temperature rise at the clamping point

If the contact resistance between the aluminum conductor and clamping point is too high, the clamping point can become very hot and even

catch re in extreme cases.

To ensure a safe and reliable contact, always perform the following work steps:

► Use a conductor cross-section at least one

number larger due to the lower currentcarrying capacity.

► Keep the installation location as free

as possible from moisture or corrosive

atmospheres. ► Connect the aluminum cables quickly. ► Mechanically clean the stripped end of the

aluminum conductor (using for instance

a knife blade to scrape off the oxide

layer), then immediately dip the aluminum

conductor into acid-fee and alkaline-free (=

neutral) Vaseline and straight away insert it

into the terminal block. ► Tighten the clamping screw in the clamping

body with the maximum permissible

tightening torque.

Additional Al-Cu compression joints and heat-shrink sleeving are required with non-sector-shaped, solid aluminum cables

► Use original tools from the manufacturer of the compression

joints for assembling the aluminum cables.

AC cabling using aluminum cables, compression joints and heatshrink sleeving

► The external diameter of the compression joints plus heat-

shrink sleeving must be smaller than the width of a clamping point on the terminal block.

Instructions regarding selection and utilization of Al-Cu compression joints

When using aluminum cables with Al-Cu compression joints (e.g. from Klauke, Elpress or Mecatraction) and heat-shrink tubing, observe the following instructions.

► Select compression joints suitable for the type of cable that

is used.

► Comply with the installation instructions issued by the ma-

nufacturer of the compression joints.

► Secure the cables with an external strain relief element.

► Selection of the protective devices for the grid cables to

the transformer of the mains feed-in point: Always take into account the impedance between the PE of the inverter and the system and/or operational ground of the distribution network. This applies in particular to TT and IT networks.

Residual current circuit breaker

Due to its design, the inverter cannot supply the mains with DC residual current. This means that the inverter meets the requirements of DIN VDE 0100-712. Possible error events were assessed by Delta in accordance with the current installation standards. The assessments showed that no hazards arise from operating the inverter in combination with an upstream, type A residual current circuit breaker (FI circuit breaker, RCD). There is no need to use a type B residual current circuit breaker.

Minimum tripping current of the type A residual current circuit breaker

≥300 mA

The required tripping current of the residual cur-

rent circuit breaker depends rst and foremost

on the quality of the solar modules, the size of the PV system, and the ambient conditions (e.g. humidity). The tripping current must not,

however, be less than the specied minimum

tripping current.

current of the DC connections when planning the installation.

Polarity of the DC voltage

► Check the polarity of the DC voltage of the DC strings befo-

re connecting the solar modules.

DC Disconnection switch

France: The DC isolating switch meets the regulations of UTE 15-712-1 (VDE 0100 712).

Safety notice

► Turn the DC disconnector to the 0 (OFF) position before

connecting the solar modules.

ATTENTION

Ingress of moisture.

Moisture can enter via open DC connections.

► To ensure protection degree IP65, close un-

used DC connections with the rubber plugs that are attached to the DC connections.

Integrated string fuses and DC surge protection devices

► Replace damaged string fuses with devices of the same

type and from the same manufacturer.

► Surge protection devices are available from Delta.

Tools

The protective caps lock the DC plug so that it can only be disconnected from DC connections using the mounting tool.

► Observe the local regulations with

regards to the protective caps. France: The protective caps must be used.

Mounting tool for disconnecting the DC plug and the protective caps from the DC connections. Available from MultiContact.

Utilization of thin lm modules

Thin lm modules can be connected to a maximum of 2 DC connections per DC input in accordance with the following connection diagram.

1 Use MC4 branch socket PV-AZB4 (Stäubli order number

32.0018) or MC4 branch socket PV-AZS4 (Stäubli order number 32.0019).

2 Use MC4 fuses of the Stäubli "In-Line-Fuse PV-K/ILF"

series.

3 The M88H_122 (CF) is factory-equipped with 15A string

fuses in the wiring box. These can be replaced by string fuses with a maximum of 20 A.

When doing so, use 20-A string fuses manufactured by Littelfuse (Littelfuse part number: 0SPF020.T).

2 2

► Use only the original parts specied above

from Stäubli (formerly Multi-Contact) or Littelfuse!

Protective devices

When selecting the necessary protective devices (e.g. fuses) take into account the Maximum reverse current of the solar modules.
