1.3 Power Supply Unit
The Power Supply Unit PSU-004 does not contain usual operating controls. There- fore, it can be installed in any recessed place either in vertical or horizontal posi- tion. (For the console mount display unit, the PSU-004 can be installed inside the console.) However, select a dry and well-ventilated location and observe the com- pass safe distances below to prevent deviation of a magnetic compass: Standard compass, 0.50 m, Steering compass, 0.30 m. Fasten the unit to chosen location with four M6 screws.
