Introduction
Enclosed type switching power supplies possess a metal or plastic case for covering their internal PCB and will be
installed inside the case of the end system. Mean Well’s enclosed type power supplies include 2 different groups of
power supplies, with built-in fan and without built-in fan, depending on their rated power or design concept.
Installation
（
1
）
Before any installation or maintenance work, please disconnect your system from the utility.
Ensure that it can’t be re-connected inadvertently!
（
2
）
Keep enough insulation distance between mounting screws and internal components of power supplies. Please
refer to case drawing on specifications to receive the maximum length of mounting screw.
（
3
）
Mounting orientations other than standard orientation or operate under high ambient temperature may
increase the internal component temperature and will require a de-rating in output current. Please refer to
the specification sheets to receive the optimum mounting position and information about the de-rating curve.

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.
