4.1 Start-up of the Power Box
4 Operation and maintenance
4.1 Start-up of the Power Box
Ensure that the following conditions are met before you put the Power
Box into operation together with the 899 Coulometer:
￭ The rear panel of the Power Box must be at least 10 cm away from
parts or devices that can generate sparks.
￭ The Power Box must be fully charged.
4.1.1 Charging the Power Box
When the Power Box is fully charged, the 899 Coulometer can be operated without a mains supply for at least 12 h. Once the charge drops
below a critical limit, you are prompted via a message on the coulometer
to charge the Power Box.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
Fully charging the Power Box takes at least 14 h. If there is too little time
for charging after approximately 8 h of operation using the 899 Coulometer, the Power Box can be charged once for 1 h. Afterwards the charge
will suffice for approximately another 8 h of operation. After that, however, the Power Box must be charged for at least 14 h.
To charge the Power Box, proceed as follows:
Plug in the plug for the power supply unit at the mains connection
1
socket (2-1) for the Power Box.
Connect the power supply unit to the mains supply using the mains
