6 ...Electrical connections
Cable entries
The electrical connection is made via cable entries with a ½
in-NPT or M20 × 1.5 thread.
Devices with a M20 × 1.5 or ½ in-NPT thread are equipped
with protective plugs.
The black protective plugs in the cable glands are intended to
provide protection during transport.Any unused cable entries
must be sealed with sealing plugs before commissioning in
accordance with the applicable national standards.
• Observe maximum torque of 3.3 ft.lb (4.5 Nm) when
tightening the M20 cable gland.
• Make sure that the cable outer dimension used will fit the
clamping range of the cable gland.

Installing the connection cables
General information on cable installation
Ensure that a drip loop (water trap) is used when installing
the connecting cables for the sensor. When mounting the

cable conduits, there is a possibility that moisture may
get into the terminal box as a result of condensate
formation in the cable conduit.
• Make sure that the cable conduits on the terminal
box are sealed.
