Caution! Voltage may still be applied on the high-tariff terminals, especially terminals A1/Z1 and A2/Z2
from the central charge control, even if the heater circuit breakers are switched off.
Caution! There must be a continuous voltage (ON-PEAK connection cable) on terminals L and N in
order to supply the electronic charge and discharge control and fan.
