Introducon
An open frame (PCB) type switching power supply is a power supply designed to be integrated or installed into a
system enclosure. Mean Well’s open frame (PCB) type power supplies include on board, general PCB, green PCB,
and medical PCB types .
Installaon
（ ）1Before commencing any installation or maintenance work, please disconnect your system from the
ulity. Ensure that it cannot be re-connected inadvertently!
（ ）2At least 5mm insulaon distance on the boom of the unit should be kept and a Mylar lm should be
added between the unit and the system. In addion, enough insulation distance, for keep 10mm
general type/15mm for medical type, around the unit.
（ ）3Power supplies greater than 120W may require a forced air/fan for cooling. Please refer to
specicaons to receive a minimum air intensity and air-ow direcon.
（ ）4Allow good venlaon for the unit in use to prevent it from overheang. Also, a 10-15 cm clearance
must be kept when the adjacent device is a heat source.
（ ）5Mounng orientaons other than standard orientaon or operate under high ambient temperature
may increase the internal component temperature and will require a de-rang in output current.
Please refer to the specicaon sheets to receive the opmum mounng posion and informaon
about the -rang curve.de
（ ）6Recommended wires are shown as below.
（ ）7 For other informaon about the products, please refer to www.meanwell.com for details.
Warning / Cauon !!
（ ）1Risk of electrical shock and energy hazard. All should be examined by a qualied technicianfailure .
Please do not try to x the power supply by yourself!
（ ）2Please do not install power supplies in places with high moisture or near the water.
（ ）3Please do not install power supplies in places with high ambient temperature or near re source.
Please refer to the specicaons about the maximum ambient temperature limitaons.
（ ）4Output current and output waage must not exceed the rated values on specicaons.
（ ）5The ground (FG) must be connected to earth ground.
（ ）6All MW’s PSUs are designed in accordance with EMC regulaons and the related test reports are
available by request. Since they are belong to component power supplies and will be installed inside
system enclosure, when they are integrated into a system, the EMC characteriscs of the end
system must be re-veried again.
