Startup for Plug-Receptacle Units

To start a plug-receptacle unit:

1. Plug the power cable of the unit into an approved, functional power

outlet.

2. If external battery cabinets are installed, check the cable

connections between the UPS and external battery cabinets.

Close the DC disconnect switch button on the back of each external

battery cabinet. Insert the switch key supplied with the cabinet into

the button and turn clockwise 1/2-turn. Pull the button out to close

the switch. Turn the key back counter-clockwise, and remove the

key.

3. Ensure that all power modules are properly installed and latched

into the UPS cabinet.

4. If you are installing power management software, connect your

computer to the UPS communication port (shown in Figure 49)

using the supplied communication cable.

5. The UPS front panel display automatically turns on whenever input

power is present and at least one power module is installed. Set up

the initial operating parameters through the front panel display (see

“Initial Startup Parameters” on page 74).

NOTE The unit has no physical On/Off switch. Access the UPS On/Off function through the

front panel display.

NOTE If the UPS has been manually set to operate in Bypass or Battery mode, change the

System Control Mode Preference (menu 4 1) selection to Auto to return to normal Auto mode

operation.
