Delta PJH Series 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 reason, please ensure the mounted device is kept at ≥ 8mm safety distance for D1 from other components
and equipments. Please insert an insulation sheet between the system and product, if the safety distance is < 8mm for D2
(Refer to Fig. 2.1)
• Installation of forced air, to ensure sufficient air flow, always maintain a distance and air flow direction
as recommended in Fig. 4. while the device is in operation.
• Note that 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.
• For Protection against shock to Class I with PE (protection earth) and Class II with or without FG (functional ground) product,
the two mounting holes (marked Ⓑ in Fig. 1) need to be connected together to the system's protective earth or functional ground.
Pollution degree and EMC performance with different connections please refer to product datasheet.
• 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.
