Delta PJT-27V150WBNA Instruction Manual

Instruction Manual
1. Safety Instructions
• The device is not recommended to be placed on low thermal conductive surface, for example, plastics.
• For safety reasons, please ensure the mounted device is kept at ≥ 8mm safety distance at all sides from other
components and equipments (Refer to Fig. 2). Please insert an insulation sheet between the system and product, if the
safety distance is < 8mm for D2*.
• Note that the enclosure of the device can become very hot depending on the ambient temperature and load of the power
supply. Do not touch the device while it is in operation or immediately after power is turned OFF. Risk of burning!
• Do not touch the terminals while power is being supplied. Risk of electric shock.
• Prevent any foreign metal, particles or conductors to enter the device through the openings during installation. It can
cause: Electric shock; Safety Hazard; Fire; Product failure.
• Warning: The power supply must be mounted by metal screws onto a grounded metal surface. It is highly recommended
that the Earth terminal on the connector be connected to the grounded metal surface.
For optimum EMI performance, the two mounting holes (marked Ⓑ in Fig. 1) need to be connected together to the
system's protective earthing (PE). Protective bonding conductor from the end product protective earth terminal can be
tied to the input FG (marked Ⓑ in Fig. 1). Under this mounting condition, there is no galvanic isolation between Output
to FG.
