Supply
DANGER
The gauge may only be connected to power sup-
plies, instruments or control devices that conform
to the requirements of a grounded protective extra-
low voltage (SELV) and limited power source
(LPS), Class 2. The connection to the gauge has to
be fused.
Supply voltage
at the gauge
Class 2 / LPS
+14 … +30 V (dc) or
±15 V (±5%)
Ripple ≤ 1 V

The gauge is protected against reverse polarity of the supply
voltage and overload.
Electrical connection 15-pin D-Sub, male
Sensor cable 15-pin plus shielding
Cable length
Supply voltage 15 V ≤ 4 m (0.14 mm²/conductor)
≤ 7 m (0.25 mm²/conductor)
Supply voltage 24 V ≤ 20 m (0.14 mm²/conductor)
≤ 35 m (0.25 mm²/conductor)
Supply voltage 30 V ≤ 40 m (0.14 mm²/conductor)
≤ 70 m (0.25 mm²/conductor)
For longer cables, larger conductor cross-sections are required
(R
