1. Verify that the UPS equipment is isolated from its external power source and all the UPS power isolators are open.
Check that these supplies are electrically isolated and post any necessary warning signs to prevent their inadvertent
operation.
2. Open the UPS door and remove the protective cover at the lower part in the front to gain access to the power
terminals, as shown in Figure 1-4 to Figure 1-6.
