Proceed with the supplied cable entry plate as described for option 1.
Option 3 - Supplied blanking plugs
For older hybrid storage systems models, it may be the case that there is no matching
opening for the supplied cable entry plate. Then the two supplied blanking plugs with mem-
brane grommet can be used.
„
Remove the two blanking plugs that are shown in the following illustration:

Using a suitable tool, make appropriate openings in the membrane of the supplied
blanking plugs.
„
Attach the plugs in the openings of the storage system.
„
Pass the two battery cables and the earthing cable through the larger plug.
„
Pass the control signal cable through the second plug.
Alternative: Cable gland with multiple sealing insert
Instead of the existing or supplied cable entry options, cable glands can also be used, which
needs to be selected depending on the diameter of the opening in the storage system. It is
important to use a multiple sealing insert if several lines are being led through one cabled
gland.
