3.9 Electrical Data
Note: If the equipment is certified for use in a hazardous area, refer to
the publication "Calibration data and instructions" for additional
data.
WARNING: Switch off and isolate the power supply before connecting or
disconnecting the transmitter.
CAUTIONS:
1.
The transmitter uses DC power in a 2-wire system to control current
through a resistive load.
2.
Do not apply more than 35 Volts to the loop circuit. The transmitter
may be damaged.
General
The electrical installation must comply with local wiring codes and standards.
To get the full performance from the transmitter, carefully choose the wiring
scheme to be used and take care connecting the transmitter.
