CE Mark Specific Safety Requirements   

 

• 

This equipment meets all applicable safety directives (as specified in prEN50178) required to qualify for the 
application of the CE marking. 

 

• 

This equipment must be installed in accordance with the applicable requirements, or prEN50178 and EN60204-1 / 
IEC-204-1. 

 

• 

This equipment is qualified to operate at Pollution Degree II and Insulation Category II. 

 

• 

The installation of this equipment must assure that the AC power input connector (UL/CSA) is not accessible to 
the user/operator. Access may be gained only by a qualified service technician. AC Mains connector installation 
must be in accordance with local requirements. 

 

• 

This unit provides appropriate separation between all interface, mains and output circuits in accordance with 5.2.18 
of prEN50178. 

 
 

Interlock System 

 

• 

The low voltage (24 V) safety interlock circuit is designed to disable the unit in the event of an interlock fault 
condition. At a minimum, interlock protection is located at the removable top cover, bottom cover and RF output 
connector safety cover. 

 

• 

End user’s system should provide indication to the operator of the interlock fault condition.   

 

• 

Low voltage power for the interlock circuit is supplied by a step down transformer located inside the unit. This 
transformer is designed to provide safe low voltage operation and provide isolation from the main AC line. 

 
 

Lockout/Tagout 

 

 

Prior to performing system maintenance, repair or other service operations the generator must be locked out and tagged 
out to prevent accidentally energizing the system. 
 
The following steps should be performed only by a qualified service technician: 
 

• 

Disconnect AC input power to the generator. 

 

• 

Mount a suitable “Clamshell” type lockout device to the AC input plug such as a Hubbell # HLD2 or equivalent. 
Follow all manufacturers’ directions for the lockout device. 

 

• 

Secure the lockout device with an appropriate padlock or safety lock. 

 

• 

Apply a lockout warning tag to the lock out device. 

 
The Lockout / Tagout device should not be removed until system service is completed and it has been determined 
appropriate to reconnect and operate the generator.
