To pre ven t pe rsona l in jur y or pr ope rty damag e an d to ensur e lo ng-term operation of the product, read this section carefully and follow all safety precautions at all times.
Danger to life due to high voltages in the Connection Unit
High voltages that can cause fatal electric shocks when touched are present in the live components of the Connection Unit.
• All work on the Connection Unit must be carried out by qualified persons only.
• Before working on the Connection Unit carry out the following steps: – Switch off all devices that are connected to the Connection Unit (e.g. inverter) and protect
against reconnection. –Cover the PV modules. – Turn the DC switch-disconnector of the Connection Unit counterclockwise by 90° and set
to OFF.
• While operating the Connection Unit, do not remove the sealing plugs.
• All work on the Connection Unit should only be carried out as described in this document.
Danger to life due to operating a damaged Connection Unit
Using a damaged Connection Unit can lead to serious or lethal injuries through electric shock.
• Only operate the Connection Unit when it is functioning properly and safely.
• Regularly check the Connection Unit for visible damage.
• Ensure that all safety equipment is freely accessible at all times.
Damage to the Connection Unit due to electrostatic discharges

Item Designation
A DC switch-disconnector
B Captive screws of the lid
CType label
In the Connection Unit the PV array strings are combined and routed into the inverter via cables. The integrated fuse holders are designed to be used with string fuses for overcurrent protection. The Connection Unit is equipped with a DC switch-disconnector and therefore serves as a DC disconnection unit.

Opening for padlock to protect against restarting
When the DC switch-disconnector is switched OFF, it can be protected against restarting with a padlock via one of the three openings.

4.4 String Fuses

St rin g fu ses are use d to pro tec t wi rin g an d equi pme nt f rom exc essive currents that can cause damage, heating, or in extreme cases, even fire.
If the string fuses are designed too small, they may open too early and cause interference. If the string fuses are designed too large, they do not provide the required protection as they open too late.
In PV s yst ems , th e mini mum and max imum s ize of t he s tri ng fus e is det erm ine d by th e el ect ric al n omi nal sizes of the PV module as well as by UL and National Electrical Code manufacturer of the PV modules in order to obtain the corresponding nominal sizes of the string fuses.
The maximum nominal size for string fuses in the Connection Unit is 20 A.
