2.1.4 Accumulator
The accumulator or battery is to be connected always. It is absolutely necessary to pay attention to
the specified polarity (
red
->
+
,
black
->
-
)!
Remark:
When changing the accumulator, or with active power- or solar-supply please take care
that the red cable is not in contact with the housing parts (danger of short-cut)
During the installation please take care that all connections are voltage-free, and
that people and/or instruments are not endangered!
When replacing the accumulator with active power supply please take care that the red cable has
no contact with any part of the housing (danger of short-circuit).
A replacing or loading is necessary at the latest when the indicated accumulator voltage decreases
below 9.0V. However, a discharge of the accumulator below 11,0 V should be avoided, as no
considerable capacity is available any more. With operation below 10,5 V the life time of the
accumulator is reduced considerably! The new accumulator should be newly charged before
mounting, because, possibly, it might not have its maximum capacity due to self-discharge (approx.
3 % per month). The stored data are being secured during the replacement. Before disconnecting
the accumulator, the data should be saved. Without accumulator no measurements are being
carried out.
2.1.5 Mains
supply
Safety Notes if using mains supply:
Attention! High Voltage. Mortal Danger!
The instrument must be mounted and wired only by qualified personnel, who
knows and observes the generalities of techniques, and applicable regulations
and norms.
Please keep in mind the local safety instructions.
Before carrying out any installation or service isolate unit from the mains supply!

When a Sensor-Interface(SIF, see
) board is installed (9.1756.x0.100), it is necessary to
swing open it to connect the 230V-power supply to the transformer or to check the fuses (see
). When the both screws at the head of the SIF-board are removed you can turn the board.
When the 230V-power supply cable is installed, and connected, a red LED is active at the
datalogger between clamps 1 and 2 for the function control of the charging connection. In case this
LED does not light, the fuses of the 230VAC-input and the 16VAC-output of the transformer should
be checked.
