Section 2 -

 

Safety 

This section covers the safety issues associated with the IoN 3 MHz. It describes the system safety 

features. Any inherent equipment hazards are outlined. Details on necessary precautions for safe 

operation are provided.  
When used properly, your IoN 3 MHz plasma system is very safe and has been tested to comply with 

CE standards. The purpose of this advisory is simply to point out possible hazards resulting from 

misuse of the equipment and to suggest ways of operating the equipment as safely as possible.  
 

2.1

 

Warnings  

Alerts containing the words 

NOTE

,

 CAUTION

,

 WARNING 

and

 DANGER

 are used in various 

advisories in this manual. 

x

 

NOTE

 are advisories that point out important information that is not obvious to the reader, but will 

not lead to any hazardous situations or immediate equipment damage if not followed. 

x

 

CAUTION 

implies that the action could possibly cause damage to equipment or injury to 

personnel if the proper procedures are not followed. 

x

 

WARNING 

or

 DANGER

 implies that the action places the operator in a situation that has a

 

possibility of

 injury 

or

 death if the proper procedures are not followed

. 

 
ELECTRICAL  
As with all electrical equipment powered from line voltage, caution is warranted whenever external 

panels are removed and/or electrical wiring is exposed. All electronics are designed with safety in 

mind and conform to common voltage directives. Internal DC voltages generated are +12 /- 12 volts, 

or 24 volts maximum. 

 

Electrical Hazard Warning

—

Warns personnel that special caution 

must be exercised. A caution alert stresses the importance of following 

proper operating or maintenance procedures. Otherwise, equipment 

reliability could be affected. This label is located on the back panel, left 

and right covers of the IoN 3 MHz. 

 

Do Not Open

—

Warns users to disconnect the IoN 3 MHz before 

removing cover. Only authorized personnel should open the cover due 

to hazardous voltage. This warning label should be on the left cover 

and on the vacuum pump access cover. 

The circuit breaker on the back of the system is designed to cut off the flow of electricity if the 

demand is over 10 amps. To reset the system, toggle this circuit breaker to the ON (or up) position. 

Note

: For your safety, only qualified electrical technicians should perform maintenance, repair or 

installation on the equipment.
