Safety pointers for electrical connection
DANGER!
Connecting the service voltage.
Improper connection of the electrical service voltage can be life-threatening. The system may
also be damaged. Local regulations for electrical connections must be observed at all times.
Further, the following basic principles must be observed:
Because the system has no main switch, a suitable disconnection device (switch, plug)
should be installed near the service voltage. It must be designated and easily accessible.
It is imperative that the protective conductor is connected.
The system must not be charged with voltage until the installation is completed and all
covers are mounted.
On systems with 100 .. 240 VAC service voltage, a back-up fuse with a max. operating
current of 16 A must be present. The cables must be able to withstand this load.
If malfunctions cannot be remedied, the system must be put out of operation and pro-
tected against inadvertent operation.
4.2
Location selection
Note the following points for the operating location:
Electrical supply must be ensured.
The water supply must be ensured as described in the technical data.
The water outlet must be unhindered.
The system should not be exposed to direct sunlight during measurement; the measu-
rement can be skewed by excessive external light.
Cable lengths should be long enough such that during servicing duty there is sufficient
room for movement of the photometer and its peripherals (e.g. fastening the photometer
to the docking station).
