5 Connecting to power supply

LBR • Two-wire 4 … 20 mA/HART

62273-EN-200520

5 Connecting to power supply

5.1 Preparing the connection

Always keep in mind the following safety instructions:

•

Carry out electrical connection by trained, qualified personnel

authorised by the plant operator

•

If overvoltage surges are expected, overvoltage arresters should

be installed

Warning:

Only connect or disconnect in de-energized state.

Power supply and current signal are carried on the same two-wire

cable. The operating voltage can differ depending on the instrument

version.

The data for power supply are specified in chapter "

Technical data

Provide a reliable separation between the supply circuit and the

mains circuits according to DIN EN 61140 VDE 0140-1.
Power the instrument via an energy-limited circuit acc. to IEC 61010-

1, e.g. via Class 2 power supply unit.

Keep in mind the following additional factors that influence the operat

ing voltage:

•

Lower output voltage of the power supply unit under nominal load

(e.g. with a sensor current of 20.5 mA or 22 mA in case of fault)

•

Influence of additional instruments in the circuit (see load values in

chapter "

Technical data

The instrument is connected with standard two-wire cable without

shielding. If electromagnetic interference is expected which is above

the test values of EN 61326-1 for industrial areas, shielded cable

should be used.
Use cable with round cross section for instruments with housing and

cable gland. Use a cable gland suitable for the cable diameter to

ensure the seal effect of the cable gland (IP protection rating).

Shielded cable generally necessary in HART multidrop mode.

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.

Note:

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.
