5.1 Preparing the connection
Always keep in mind the following safety instructions:
•
Connect only in the complete absence of line voltage
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. Depending on the plug connec-
tion, you have to select the outer diameter of the cable respectively so
that the seal effect of the cable gland is ensured.
•
Valve plug ISO 4400, ø 4.5 ... 7 mm
•
Valve plug ISO 4400 with IDC crimping technology, ø 5.5 ... 8 mm
Use cable with a round wire cross section and tighten the cable gland.
When mounting outdoors, on cooled vessels or in moist areas in
which cleaning is made with steam or high pressure, the sealing of
the cable gland is very important.
