necessary, disconnect the power cable from the ship
’s distribution board.
The following warning label is attached to the dangerous position of this system

Main units of this system consist of electronic circuits having high reliability. However,
it is impossible to say that no failure should happen.
Accordingly, the check and maintenance described in this chapter should be sincerely
carried out to remove failure risk as much as possible and to maintain the system
performance. Otherwise, detection of the failure sign will be delayed and may cause
distress such as collision or grounding.

Request our service engineer when trouble is detected and cannot be repaired on
board.
PROHIBITION
Do not use insulation tester or other instrument to test system insulation since it may
