Kipp&Zonen COMBILOG Data Logger - Manual (Page 28)

Note: It is necessary to take care that the current at the Module
Jack is not higher than permitted. Thus, the power supply
preferably should be led to the centre of the module line. For
the same reason a 100 mA self resettable fuse protects the
module connector of the COMBILOG 1022 against short cir-
cuits.
The permanent current drawn from the module connector shall
not be higher than 100 mA.
