rechargeable battery for the control unit can no
longer be charged via the Testo data bus cables
when the control unit is switched off. In this case
the external mains unit 0554 1096 is required in
order to charge the battery.
The CU can be used without an external mains unit during
operation, even with Testo data bus cables >90 m.
testo data bus cables must not be used during electrical
storms.
