7.3 Replacing the Electronics Unit

The UPS allows replacement of a failed Electronics Unit without interruption of power to the load.

The Isolation Unit is capable of autonomous operation and provides power to the load isolated from

EMI/RFI noise and surges.

To replace a failed EU, follow the procedures listed below.

7.3.1Put the UPS into the bypass mode of operation by actuating the manual bypass switch at the rear of the EU. Note: Transfers to bypass mode using the manual bypass switch occur within 10 mS typically. The transfer back from the bypass mode occurs in 0 mS.

7.3.2Using a coin or large flat blade screwdriver, unscrew the EU separating screw and pull back.

7.3.3Using a Phillips screwdriver, loosen the Battery Pack coupler lock at the rear of the EU and disconnect the pack coupler. Disconnect the Battery Pack communications cable from the jack at the rear of the EU.

7.3.4If necessary, disconnect cables connected at the computer interface port and the Emergency Power Off interface.

7.3.5Grasp the EU at the slots shown in the illustration and pull straight up and away from the IU.

7.3.6Follow the above procedures in reverse to install the replacement EU. Once the replacement EU is installed, press any key to regain control of the UPS.
