2.3.5 In the event of a thunderstorm
To reduce the risk of damage to electrical
components in the product and the charging
station, we recommend that all connections to the
charging station are disconnected (power supply,
boundary wire and guide wire) if there is a risk of
a thunderstorm.
1. Mark the wires to simplify reconnecting. The
charging station's connections are marked
AR, AL and G1, G2, G3.
2. Disconnect all connected wires and the
power supply.
3. Connect all the wires and the power supply
if there is no longer a risk of thunder. It is
important that each wire is connected to the
right place.
