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 UB = 30 V (DC): 5 A.
Provide a separate switch for the external power supply.
Alternative for North America: The connection may also be made to „Class 2 Circuits"
or „Class 2 Power Units" according to CEC (Canadian Electrical Code) or NEC (Nati-
onal Electrical Code).
Ingress protection per IEC 60529 (The ingress protection classes specified only apply

while the pressure transmitter is connected with female connectors that provide the
corresponding ingress protection).
Ensure that the cable diameter you select fits to the cable gland of the connector.

Ensure that the cable gland of the mounted connector is positioned correctly and
that the sealings are available and undamaged. Tighten the threaded connection and
check the correct position of the sealings in order to ensure the ingress protection.
Please make sure that the ends of cables with flying leads do not allow any ingress of

moisture.
