5 Connecting to the bus system

5.1 Preparing the connection

Always keep in mind the following safety instructions:

Warning:

Connect only in the complete absence of line voltage.

•

The electrical connection must only be carried out by trained

personnel authorised by the plant operator.

•

If overvoltage surges are expected, overvoltage arresters should

be installed.

The instrument requires a operating voltage of 9 … 32 V DC. Operat-

ing voltage and the digital bus signal are carried on the same two-wire

connection cable. Power is supplied via the H1 power supply.

Connection is carried out with screened cable according to Fieldbus

specification.
Use cable with round cross section for instruments with housing and

cable gland. To ensure the seal effect of the cable gland (IP protection

rating), find out which cable outer diameter the cable gland is suitable

for.
Use a cable gland fitting the cable diameter.
Make sure that the entire installation is carried out according to the

Fieldbus specification. In particular, make sure that the bus is termi-

nated with suitable terminating resistors.

Metric threads

In the case of instrument housings with metric thread, the cable

glands are screwed in at the factory. They are sealed with plastic

plugs as transport protection.
You have to remove these plugs before electrical connection.

NPT thread

In the case of instrument housings with self-sealing NPT threads, it is

not possible to have the cable entries screwed in at the factory. The

free openings for the cable glands are therefore covered with red dust

protection caps as transport protection.
Prior to setup you have to replace these protective caps with ap-

proved cable glands or close the openings with suitable blind plugs.
On plastic housings, the NPT cable gland or the Conduit steel tube

must be screwed into the threaded insert without grease.
Max. torque for all housings, see chapter "

Technical data

Make sure that the cable screen and grounding are carried out ac-

cording to Fieldbus specification. We recommend to connect the

cable screen to ground potential on both ends.
In systems with potential equalisation, connect the cable screen

directly to ground potential at the power supply unit, in the connection

box and at the sensor. The screen in the sensor must be connected
