Assembly
[1] PG7 cable gland pre-assembly
Screw 1-5 PG7-cable glands (PG7-thread) into the PG7 openings of the adapter.
Close unused PG7-openings with PG7-blind stuffings.
Use optional TPU PG7-sealings if necessary.
[2] PG42-adapter assembly
Place the pre-assembled PG42-adapter (blind stuffing) in the PG42 opening and secure it with a PG42 nut.
Optionally place PG42 sealing on the PG42-adapter before assembly.
[3] Cable assembly
Guide cable through PG7 cable gland and fix cable by fastening the corresponding cable gland nut.
Hint:
Apply some silicone grease on the thread, so it can be easily be assembled and disassembled.
(Without grease, the thread tends to wind on and off somewhat “sticky”.)
