2. Safety

This manual contains important safety and operation instructions for correct use of the power 
supply. Read through the manual and pay special attention to the markings and labels of this unit 
and equipment to be connected. 

Pay special attention to these two types of notices used in this manual: 

WARNING : Failure to observe this warning may cause injury to persons and damage to power 

supply or connected equipment. 

CAUTION : Failure to observe this warning may result in damage to equipment and 

improper functioning of the power supply. 

WARNING 

Do not use this power supply near water

Do not operate or touch this power supply with wet hands

Do not open the casing of the power supply when it is connected to ac mains

Refer all servicing to qualified service personnel only

Before replacing the AC fuse, determine the cause and clear up the cause first

Replace the AC fuse with the same type and rating as the original fuse

The maximum output voltage of the DCP42 exceeds 60VDC, avoid touching the metal 
contact parts at the output terminals

CAUTION 

Use a grounded 3 pin AC source
