9. If required, fit the coding pins to the connector block as shown in the appropriate figure.
Note: Harting (the manufacturer of the connector) states that after initial assembly, the recommended
tightening torque must only be reapplied once in order to avoid damage to the individual cable strands.
10.The dry pumping system has an electrical connector locking mechanism - there are two different types fitted
depending on pump variant.
For the locking mechanism for all GXS160, GXS250 and GXS450 dry pumping systems, refer to Figure 10.
This locking mechanism requires use of a suitable screwdriver to release. Referring to Figure 10, the dry pumping
system is supplied with a protective cover (item 5) fitted and the locking mechanism (item 1) may be applied. The
protective cover is held in place by two locking levers. Follow these instructions to fit the electrical supply cable:
 Slacken off the locking screw (item 3) by a few turns to loosen the locking mechanism if necessary.
 Move the locking mechanism (item 1) to the left as far as possible, then lift it up so that it rotates around the
pivot screw (item 2) and clears the left hand lever (item 4).
 Push back both levers (item 4) to release the protective cover.
 Remove the protective cover and fit the electrical supply cable.
 Pull both levers back towards the user to lock the electrical supply cable connector in place.
 Push the locking mechanism down as far as possible and then push to the right so that it prevents the left
hand lever from actuating.
 Tighten the locking screw (item 3) to firmly hold the locking mechanism in place.
 Connect the other end of the electrical supply cable to the electrical supply through a suitable isolator.
For the locking mechanism for all GXS750 dry pumping systems, refer to Figure 11.
This locking mechanism is held in place by two M5 locking nuts and requires use of a suitable spanner to release.
Referring to Figure 11, the dry pumping system is supplied with a protective cover (item 1) fitted and the locking
mechanism (item 3) may be applied. The protective cover is held in place by two locking levers (item 2). Follow these
instructions to fit the electrical supply cable:
 Slacken off the two locking nuts (item 4) by a few turns to loosen the locking mechanism.
 Move the locking mechanism (item 3) to the right as far as possible so that it clears the right hand lever
(item 2).
 Push back both levers (item 2) to release the protective cover.
 Remove the protective cover and fit your electrical supply cable.
 Pull both levers back towards you to lock your electrical supply cable connector in place.
 Push the locking mechanism as far as possible to the left so that it prevents the right hand lever from
actuating.
 Tighten the locking nuts (item 4) to firmly hold the locking mechanism in place.
 Connect the other end of the electrical supply cable to the electrical supply through a suitable isolator.
