X150.5 Owners Manual

Water and moisture:  

Electrical devices should not be used near water ( 

as per example, near a bathtub, washbasin, kitchen sink, laundry tub, wet 
basement or swimming pool ).  Care should be taken such that objects 
do not have the opportunity to fall, and that liquid is never spilled onto or 
into the device enclosure through openings.

Power Sources:  

An electrical device must  be connected to a mains 

power source in strict accordance with the supplied  product owner’s 
manual.  Please verify that the AC mains voltage specified in the product 
manual matches those requirements indicated on the unit and the AC 
voltage provided to your location by the power company.

Grounding:  

Adequate precautions should be taken so that the 

grounding provisions built into an electrical product are never defeated.

Power Cords:  

Pass Laboratories provides a power supply cord that 

meets all legislated requirements for the market in which the product was 
originally sold.  If you choose to substitute an after-market product we 
urge you to choose one that is fully safety rated by the necessary local 
authority.

Power Cord Protection:  

Power supply cords should be routed so that 

they are not likely to be walked on, abraded, or pinched by items placed 
on or against them, paying particular attention to cords where they enter 
plugs or exit from a device.  Never under any circumstance insert a cut or 
damaged power cord into a mains power socket.

Power and Signal:  

Cables should never be connected / disconnected 

with equipment powered up.  Failure to heed this warning may damage or 
destroy equipment.

Ventilation:  

Power-amplifiers run hot, but you should be able to place 

your hands on them without discomfort.  You must allow for this heat 
in installation, by providing for free air circulation around the product.  
Electronics should not be subjected to sources of excessive radiant heat. 
Excessive heat can shorten the life of the product and may cause the 
electronics to self-protect and shut down.

Servicing:  

To reduce the risk of fire, electrical shock or other injuries, 

the user should not attempt to service the device beyond that which 
is described in the operating instructions.  All other servicing must be 
referred to qualified service personnel.

For Units With Externally Accessible Fuse Receptacle: 

Unplug 

the device from all sources of power before changing  or inspecting any 
fuse.  Replace fuse with one of same physical size, type and rating as that 
specified by the manufacturer for that product.

For your protection please
