Creating Equipotential Bonding; Sealing The Connection Area - Kaco blueplanet 50.0 TL3 M1 WM OD IIGS Mode D'emploi

NOTE
Type and configuration of the PV modules.
Connected PV modules must be dimensioned for the DC system voltage in accordance with IEC 61730 Class
A, but at least for the value of the AC grid voltage
NOTE
Sizing of the PV generator
The device is designed with a reserve of DC short-circuit current withstand capability. This allows oversizing
of the connected PV generator. The absolute limit for the PV generator is the value of the maximum short
circuit current (lsc max) and maximum open circuit voltage (Uoc max).
7.6.4 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.
› Only touch the PV generator cables on the insulation. Do not touch the exposed ends of the cables.
› Avoid short circuits.
› 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 (polarity +/-) causes equipment damage in the DC connection if
it is connected permanently.
› Please check polarity (+/-) of the DC connector before connecting the DC generator.
› 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.

Creating equipotential bonding

NOTE
Depending on the local installation specifications, it may be necessary to earth the device with a second
ground connection. To this end, the threaded bolt on the underside of the device can be used.
↻ The device has been installed on the mount.
1 Strip the insulation from the equipotential bonding cable.
2 Furnish the stripped cable with an M8 ring cable lug.
3 Lay the cable for equipotential bonding onto the grounding point and attach
with an additional M8 nut and lock washer [ W_17/
4 Check that the connected cable is fitted securely.
» The housing is included in the equipotential bonding.

Sealing the connection area

1 The requirements of protection class IP65 are met by closing the unused cable fittings with blind caps.
2 Close the housing door and lock it with a control cabinet key.
