7.5.5 Connecting the PV generator
DANGER
Risk of fatal injury due to electric shock!
Severe injury or death will result if the live connections are touched. When there is sunlight present on the PV
generator, there is DC voltage on the open ends of the DC cables.
1. Only touch the PV generator cables on the insulation. Do not touch the exposed ends of the cables.
2. Avoid short circuits.
3. Do not connect any strings with a ground fault to the device.
CAUTION
Damage to the PV generator in case of faulty configuration of the DC connector.
A faulty configuration of the DC connector (po/-) causes equipment damage in the DC connection if it is connected
permanently.
1. Please check polarity (+/-) of the DC connector before connecting the DC generator.
2. Before using the solar modules, check the vendor’s calculated voltage values against those actually measured. The DC
voltage of the PV system must not exceed the maximum no-load voltage at any time.
Connecting the PV generator
↻ PV generator is dimensioned according to the performance characteristics of
the unit.
1. Remove protective caps from the required DC connection plugs on the under-
side of the device.
2. Connect the DC plug connectors to the DC positive and DC negative connectors
in pairs.
ð The device is connected to the PV generator.

7.6 Inserting the overvoltage protection
Inserting the DC overvoltage protection modules
↻ NOTE: A check has been performed to ensure there is no AC/DC
voltage present.
1. [See section 7.1 } Page 21].
. NOTE: The coding at the base plug-in position must match the cod-
ing on the module.
2. Insert the DC overvoltage protection modules into the DC base one after an-
other.
3. Secure the new modules using the interlock. [ S_3.5]
4. Ensure that all protective elements are properly secured.
ð Move on to connect remote signal monitoring or lock the housing cover. [See
section 7.9
} Page 31].
