9.4 Remote position transmitter For the connection of position transmitters (potentiometer, RWG) screened
cables must be used.
9.5 Limit switch Only the same potential can be switched on the two circuits (NC/ NO con-
tact) of each single switch. If different potentials are to be switched simulta-
neously, tandem switches are required.
For correct signalisation, the leading contacts must be connected at the tan-
dem switch.
9.6 Fitting of the cover
.
After completion of the power supply connection, insert the socket carrier
(26.2), see figure C1, page 9, into the plug cover and fasten it
with screws (2).
.
Clean sealing faces at plug cover (26.0) and check whether O-ring is in
good condition. Apply a thin film of non-acidic grease (e.g. Vaseline) to the
sealing faces.
.
Replace plug cover (26.0) and fasten 4 bolts (26.01) evenly crosswise.
.
Fasten cable glands firmly to ensure required enclosure protection.
