1. Safety Instructions
• To ensure su󰀩cient convection cooling, always maintain a safety distance of ≥ 20mm from all ventilated surfaces while the device is in operation.
• For PMH-100WCL□□, PMH-100WCM□ and PMH-150WCL□ models, always maintain a safety distance of ≥ 50mm from all four sides
while the device is in operation. The cover's top ventilated surface must be kept free from any obstructions.
• The device is not recommended to be placed on low thermal conductive surface, for example, plastics.
• 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
• The appliance is not to be used by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience
and knowledge, unless they have been given supervision or instruction.
• The power supply must be mounted by metal screws onto a grounded metal surface.
• Warning: When connecting the device, secure Earth connection before connecting L and N. When disconnecting the device, remove L and
N connections before removing the Earth connection.
• The device is earthed and must be inaccessible.
