Charge Lights (CCL's) are not illuminated.
Use measurement and protective equipment
rated for 2000 VDC minimum to verify that no
voltage is present before touching any terminal.
Verify functionality of the measurement equip-
ment using site-approved
before and after performing control group mea-
surements.
Failure to observe these precautions may result
in death or serious personal injury.
