5 Connecting to power supply
5 .1 Preparing the connection
Always keep in mind the following safety instructions:
l Connect only in the complete absence of line voltage
In hazardous areas you must take note of the respective regulations,
conformity and type approval certificates of the sensors and power
supply units.
The instrument is connected with standard two-wire cable without
screen. If electromagnetic interference is expected which is above the
test values of EN 61326 for industrial areas, screened cable should be
used.
Use cable with round cross-section. A cable outer diameter of 5 … 9 mm
(0.2 … 0.35 in) ensures the seal effect of the cable gland. If you are
using cable with a different diameter or cross-section, exchange the
seal or use a suitable cable gland.
When the optionally integrated temperature transmitter is also
connected, a four-wire cable is required; when an external temper-
ature transmitter is connected, a six-wire cable is required.
