11.2 AC Power Connections

Power connections may be disconnected from the UPS cabinet via a removable distribution box. This 

may be a convenient feature if the UPS must be moved a short distance or replaced. This box allows 

power connections to be conveniently disconnection from the main UPS cabinet. A label is attached to 

the UPS to describe these procedures.

11.2.1 Disconnect

1. DO NOT turn off the branch circuit breaker feeding power the box unless you intend to disconnect 

all power to the load.

2. Ensure that the Maintenance Bypass Lamp is ON.
3. Switch to the maintenance bypass position.

The load is now unprotected from line disturbances or interruptions.

4. Turn off the UPS using the front panel controls.

a. If needed, push the OFF button for one second once to transfer the load to bypass.
b. Press the OFF button twice within four seconds to turn the UPS off.

5. Turn off the UPS input circuit breaker on the box at the rear of the UPS.

This input circuit breaker cuts off power only from the connector between the box and UPS. The 

input circuit breaker does not cut off power from the manual bypass switch.

6. Turn off the output circuit breaker on the rear of the UPS.
7. Remove the distribution box from the UPS

a. Loosen all three captive screws until the box releases.
b. Pull box away from the UPS and set the box aside on a padded surface.

8. Loosen the cover over the electrical connections by backing out the three screws one turn each.
9. Slide the cover over the electrical connections.
10. Gently retighten the three screws loosened in 

Step 8

.

Whenever the power distribution box is not attached to the UPS, the cover must be slid over the 

electrical connections to prevent damage or injury.
