4.2.2.  SAFETY OPTIMIZATION  
In all cases, a safety loop used properly is the best protection. 
 
 
The system of protection is ideal for the equipment under test and for the operator; it is inde-
pendent of the voltage applied and the current injected for measurement.
 
 
 
 
 
WARNING
 
Danger of electric shock! 
• Access to the device must be limited to personnel "informed about elec-
trical hazards".  
• We strongly advise against handling equipment under test (risk of faults 
and electric shock). 
 
A double safety loop is offered as the basic equipment. 
 
 
WARNING
 
 For dangerous voltages, signalling by a suitable Red/Green light (SEFO-
CO160 option) must be put in place.
 
 
EATON can provide, on request, a locking system implemented during the test to control a safe-
ty cage type CA001, CA002 (image below) or CA003 in order to make the tests in complete 
safety.
