.
NOTE
Use standard M20 x 1.5 cable gland nuts to ensure leakage (IP-protec-
tion of the housing) and for the necessary tensile strength use only
cables with a cable diameter ≥ 8 mm, or for smaller diameters use a
suitable sealing insert.
For the NPT version, the positioner will be delivered with an adapter.
Make sure that when fitting a part into the adapter, that the maximum
permissible torque of 10 Nm is not exceeded.
NOTE for use in zone 2:
Non-sparking equipment for Zone 2 may not be connected or discon-
nected under power in normal operation.
However, during installation or repair work the positioner may be con-
nected or disconnected even under power (see also certificate for
zone 2).
NOTE for use in two-wire systems:
Never connect the current input (terminal 6 and 7) to a voltage source
as this could destroy the positioner.
Always use a current source with a maximum output current of 20 mA.
To maintain the power supply, the input current must be ≥3.6 mA.
