Operating Instructions
Electrical connection
Connect the instrument to earth via the pressure connection.
For power supply, use a circuit with energy limitation (EN/UL/IEC 61010-1, section 9.3)
with the following maximum values for the current: with L + = 35 V (DC): 4.0 A. Provide a
separate switch for the external power supply. Alternative for North America: The connec-
tion may also be made to „Class 2 Circuits" or „Class 2 Power Units" according to CEC
(Canadian Electrical Code) or NEC (National Electrical Code).
Zero-point adjustment: Check the zero point shown on the display during commissioning.
If, for installation reasons, an offset is displayed, this can be reset in programming mode
using the 0SET parameter.
