•
Electrical connection in accordance with VDE 0100 ”Regulations governing heavy-current
installations with line voltages up to 1000 V” or equivalent others national regulations.
•
Do not cross or loop cables.
•
Use separate cable entries (see below) for power supply, field current cables, signal lines,
outputs and inputs.
•
Protect flowmeters or switchgear cabinets with built-in devices from direct sunlight. Fit a
sunshade if necessary.
•
When installed in switchgear cabinets, signal converters must be adequately cooled, e.g.
use fans or heat exchangers. (dust-free air and no aggressive gases)
•
Do not expose signal converters to intense vibration.
•
Keep distance between primary head and signal converter as short as possible. Refer to
Sect. 1.3.4 for maximum permissible length of signal and field current cables.

ensure primary constant GK is identical; refer to instrument nameplate for the primary
head.
If the GK is not identical, set the signal converter to the GK of the primary head.
