General Safety Issues
The power supply documented in these instructions has been designed, tested and
produced to ensure safe, trouble-free operation. Personnel using or installing this power
supply should completely read and fully understand the following safety instructions. They
are provided here as informational guidelines for your continued safety in usage of the
product. These general safety issues should be observed in all phases of power supply
installation and service.
This power supply uses two sources of electrical power: commercial AC and DC derived
from a battery. Whenever performing maintenance on any of the internal components, you
must disconnect both the battery cable and AC line cord.
Always use proper lifting techniques when handling the power supply or batteries. Both the
power supply and a single 12-volt battery weigh approximately the same, about 65 pounds
(30 Kg).
Personnel installing or servicing batteries must wear eye protection (goggles or full face
shield) and protective clothing (apron and gloves) as mandated by standard operating
procedures. Additionally, only fully insulated tools specifically designed for battery
installation and service should be used for that purpose. Tools wrapped with vinyl or fabric-
based electrical tape are NOT acceptable substitutes.
