The UPS contains potentially hazardous voltages. Do not open the unit; there are no user serviceable parts inside.
All maintenance and service work,
except replacement of the batteries
, should be performed by qualified service personnel.
After switching UPS unit OFF, wait two (2) minutes for the DC capacitors to discharge. Lethally high voltage may remain
