Connecting the SICON (M)
DANGER!
Life-threatening voltage inside the instrument.
Connecting electrical lines can be extremely dangerous. Instrument parts may also be dam-
aged. Local regulations for electrical installations must be observed at all times.
5.4.1
Cable cross-sections over longer distances
For connections longer than the standard cable length of 5 meters, an optional junction
box must be connected between the photometer and control unit.
Depending on the cable used (cross-section) and power supply, the distance between
the control unit and the photometer can be calculated according to the table below.
For cable lengths of more than 5 meters, shielded cable must be used.

The maximum distance (X) between the control unit and junction box depends on the volt-
age in the SICON and the cable cross-section used:
