1.5.2 Mounting method
Fasten the interface unit with four self-tapping screws (5X20, local supplied).
For bulkhead mounting, do as follows:
1. Tighten upper self-tapping screws so there is 5 mm clearance between
bottom of screw head and bulkhead.
2. Hook the transceiver unit on the upper screws.
3. Tighten the upper screws followed by the lower screws.
