Installation Notes
A.Before any installation or maintenance work, please disconnect your
system from the utility. Ensure that it cannot be re-connected
inadvertently.
B.Keep enough insulation distance between mounting screws and
internal components of power supplies. Please refer to 2.5 Mechanical
specification to receive the maximum length of mounting screw
C.Mounting methods other than chapter 3.1 or operate under high
a m b i e n t t e m p e r a t u r e m a y i n c r e a s e t h e i n t e r n a l c o m p o n e n t
temperature and will require a de-rating in output current.
D.Fans and ventilation holes must be kept free from any obstructions. Also
a 10-15 cm clearance must be kept when the adjacent device is a heat
source.
Cable connections should be as short as possible and make sure that
suitable cables are chosen based on safety requirement and rating of
current. Small cross section will result in lower efficiency, less output
power and the cables may also become overheated and cause danger. For
selection, please refer to table 3-1.

Note: Current each wire carries should be de-rated to 80% of the current
Make sure that all strands of each stranded wire enter the terminal connection and the screw
terminals are securely fixed to prevent poor contact.
