Wiring
The CONTOUR can be connected in different modes and configurations for different
external systems such as PLC or DCS and communications on RS485, ModBus, and
HART and also to RS485 bus converting adapters to communication gateways such as
CONTOUR Connect for GMS or GPRS data relay and TCP/IP gateway. For in-depth
details and explanations on wiring and communication, refer to
page 23: Different
Connection Methods
.
Use 8-13mm (20-24 AWG) diameter cables to ensure proper and effective sealing of
the cable gland entry opening.
Select a cable suitable for application (indoor or outdoor) and safety certified
according to national regulations.
Communications
NOTE:
If electromagnetic interference is expected, usage of a screened and
twisted wired cable is recommended for the signal lines, which should be
connected to the ground reference.
CAUTION
: Always observe the following safety instructions:
Connections must be made only in the complete absence of line voltage.
If over-voltage is expected, overvoltage arresters should be installed.
Use only a safety-certified power supply with dual insulation between the primary
and output for powering the unit. The power supply output rating must be limited
to 20-32VDC, 1A for a single CONTOUR device, and not to be connected to a DC
distribution network.
In hazardous areas you should take note of the appropriate regulations,
conformity and type of approval certificates of the sensors and power supply
units. Refer to the printed safety manual provided with the ATEX/FM approved
CONTOUR
