1.5 Power Supply Unit
Mounting considerations
The power supply unit may be mounted on a bulkhead or a deck. Because it has no operation
requirements it can be located almost anywhere, provided the location is well ventilated.
Mounting procedure
Fix the unit to the mounting location with four 6×20 self-tapping screws (local supply). For
mounting on a bulkhead, do the following:
1. Mark location for mounting holes.
2. Screw in the self-tapping screws at the location for the bottom fixing holes, leaving a gap of
about 5 mm between the bottom of the screw head and bulkhead.
3. Set the unit to the screws inserted at step 1.
4. Fasten the self-tapping screws at the top of the unit.
5. Tighten all self-tapping screws.
