IMPORTANT SAFETY INSTRUCTIONS 

1) Read these instructions. 
 
2) Keep these instructions. 
 
3) Heed all warnings. 
 
4) Follow all instructions. 
 
5) Do not use this apparatus near water. 
 
6) Clean only with dry cloth. 
 
7) Do not block any ventilation openings. Install in 
accordance with the manufacturer’s instructions.  
 
8) Do not install near any heat sources such as 
radiators, heat registers, stoves, or other 
apparatus (including amplifiers) that produce heat. 
 
9) Do not defeat the safety purpose of the 
polarized or grounding-type plug.  A grounding 
type plug has two blades and a third grounding 
prong. The third prong is provided for your safety. 
When the provided plug does not fit into your 
outlet, consult an electrician for replacement of the 
obsolete outlet. 
 
10) Protect the power cord from being walked on 
or pinched particularly at plugs, convenience 
receptacles, and the point where they exit from the 
apparatus. 

 

11) Only use attachments/accessories specified by 
the manufacturer.  
 
12) Unplug this apparatus during lightning storms or 
when unused for long periods of time. 
 
13) Refer all servicing to qualified service 
personnel. Servicing is required when the 
apparatus has been damaged in any way, such as 
power-supply cord or plug is damaged, liquid has 
been spilled or objects have fallen into the 
apparatus, the apparatus has been exposed to rain 
or moisture, does not operate normally, or has been 
dropped. 
 
14) WARNING - To reduce the risk of fire or electric 
shock, do not expose this apparatus to rain or 
moisture. 
 
15) The MAINS plug or appliance coupler is used 
as the disconnect device.  This disconnect device 
must remain redily accessible after installation. 
 
16) In order to comply with international safety 
requirements for operating temperature, clearance 
of at least 5cm or 1.97" must be maintained 
between this device and other rack-mounted 
devices. This spacing will ensure that all exposed 
metal surfaces are safe to touch. 

 

 
 

Explanation of safety related markings and symbols which appear on the outside of the apparatus. 

 

 

Lightning Bolt:  Hazardous Live voltages present when this unit is in operation.  Do not touch terminals 
marked with this symbol while the unit is connected to live power. 
 

 

Exclamation Point:  Replace components (i.e. fuses) only with the values specified by the 
manufacturer.  Failure to do so will compromise safe operation of this unit.
