Be careful of high voltage inside
High voltage, which may risk you life, is used. This high voltage may
remain in the circuit even after the power is switched off. To prevent
contact with the high voltage circuits accidentally, a protective cover or
the label with this mark is provided on the high voltage circuit. When the
inside is to be checked, ensure to switch off the power and to discharge
the residual voltage for safety. An engineer authorized by Koden shall
carry out the inspection and maintenance works.
Power off in the boat
An accidental power-on during works may result in worker's
electrification. To prevent such accident in advance, ensure that power
in the boat and on the equipment are switched off. Furthermore, it is
safer to hang a caution tag saying "Under work" near the power switch
of equipment.
Be careful of dust
Inhaled dust may cause respiratory affection. At the time of cleaning the
inside of equipment, be careful not to inhale dust. Wearing a safety
mask is recommended.
Caution on location of installment
The equipment shall not be installed at locations which are excessively
damp and suffers from water drops. Otherwise, dew condensation may
