CAUTION

Machineandequipmentdamagemayoccur.

► Observe the pin assignment of the AC bayonet connector. An incorrect

assignment can result in the unit being destroyed. The Figure 5.5 pin

out diagram shows the connections inside the AC connector.

NOTE

Make sure the line is provided with a strain relief device. When using cables

with a diameter of less than 13 mm (11mm...13mm diameter cable

require strain relief), the cable must be relieved just behind the connector.

The connection to the Amphenol AC connector for both models can be made with a exible or

rigid cable with a copper conductor that has a cross section greater than 4.0 mm

and which has

an installation condition that gives a correction factor equal to one. The AC cable should be pro-

tected by a minimum type B 40 Amp breaker.

This connector is developed for connection to copper wires (for other applications please contact

Amphenol). The cross section of the cable should be calculated by considering the material used,

thermal conditions, length of the cable, the type of installation, and AC voltage drop.

Please note the cable length and the cable cross-section, due to the risk of undesirable tempera-

ture rise and power losses. In some countries (e.g. France, Germany) system installation require-

ments have to be followed (UTE 15712-1, VDE 0100 712). This recommendation will dene mini-

mum cable sections and protections against overheating due to high currents. Please make sure

that you follow specic requirements in your country.

For the security of your installation and for the safety of the user, please install required safety and

protection devices that are applicable for your installation environment (example: automatic circuit

breaker and/or overcurrent protection equipment).

WARNING

Deathandseriousinjurymayoccur

In the case of damage or bodily harm resulting from the use of this device

in a way contrary to it’s intended purpose or as a result of unauthorized

modications made to the parameters of the inverter, Delta will not be held

liable in these situations..

The solar inverter must be grounded via the AC connector’s PE conductor. To do this, connect the

PE conductor to the designated terminal.

The AC connector is protected from unintentional disconnection by a clip mechanism which can

be released with a screwdriver.
