Creating Equipotential Bonding; Connecting The Interfaces - Kaco blueplanet 50.0TL3-R Operating Instruction

7 | Installation
NOTE
When the line resistance is high, i.e. long cables on the grid side, the voltage at the grid terminals of the device
will increase in feed-in mode. If the voltage exceeds the country-specific grid overvoltage limit value, the device
switches off.
1. Ensure that the cable cross-sections are sufficiently large or that the cable lengths are sufficiently short.

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. Check that the connected cable is fitted securely.
ð The housing is included in the equipotential bonding.

Connecting the interfaces

7.5.1 Overview
DANGER
Risk of fatal injury due to electric shock!
Severe injury or death may result from improper use of the interface connections and failure to observe pro-
tection class III.
1. The SELV circuits (SELV: safety extra low voltage) can only be connected to other SELV circuits with protec-
tion class III.
CAUTION
Damage to the device from electrostatic discharge
Components inside the device can be damaged beyond repair by static discharge.
1. Observe the ESD protective measures.
2. Earth yourself before touching a component by touching a grounded object.
NOTE
Due to the installation position of the communication circuit board, this must be specially safeguarded against
moisture and exposure to dust.
1. Make sure that no moisture or dust impacts on the circuit board during installation. Moisture and dust
particles must be removed immediately. In doing so, disassembly of the circuit board may be necessary.
All interfaces are located on the communication circuit board on the inside of the housing door.
