Assembly of the unit
1. Mounting of the Extension tube to oscillating piece
and preparing cables
The tube must be assembled very carefully to
ensure permanent sealing and mechanical
stability. Observe the follow mounting instruction.
Make sure, that the thread of the extension tube
and the thread of the screwed piece/ oscillating
piece is the same type (do not mix G and NPT
thread).
1.1. Feed the connecting wire through the 1“ Extension tube.
Use a separate taut wire for easy working.
1.2. Screw the 1“ Extension tube into the oscillating piece.
Tightening torque 50 Nm.
Use a 36 mm (1.42“) open-end wrench, do not turn the
oscillating rods.
G version: Tighten the Fixing screw
Requirements for sealing:
There must be a seal connection between the 1“ tube and
the screwed piece and the oscillating piece (IP67 or
NEMA 4).
G version: An O-ring is required at both ends to ensure
proper sealing and must not be damaged. Only original
O-rings from the manufacturer are allowed to be used.
NPT version: The thread must be sealed with temperature
resistant sealing for 150°C (302°F). Max. thickness of the
sealing is 0.2 mm (0.008").
