housing (5)
Take note of the correct direction when inserting the electronics
module. The electronics module cannot be inserted the wrong
way. Keep the plugs on the lower side in mind.
Note:
If the optical pad (4) drops out when inserting the electronics module,
you have to clean the optical pad (4) carefully, grease it again, remove
the grease (only a thin film should remain) and place it again onto the
photomultiplier (8).

26. Plug the already connected terminal blocks (6) carefully onto the
new electronics module (2).
Note:
The terminal blocks are uniquely coded according to the electronics
version.
If one of the terminal blocks does not fit onto the electronics module,
check if you are using the right electronics module.
If the electronics module is correct, check the coding.
See chapter "Mounting preparations".
