Description of Figures 1.4, 1.5, and 1.6:

1.External I/F Board (IOAU-05) : FOR SERVICE PERSONNEL ONLY (FIGURE 1.6):

-(3) External contact signal terminal

-(4) RS232C communication connector

2.Grounding Bar (E)

3.External Contact Signal Terminal Block - Terminal block to connect contact signal input/output lines to and from the external devices. Refer to Figure 2.15 section 2.5 for details.

4.RS232C Communication Connector - Refer to Figure 2.18 section 2.6 for details.

5.“INVERTER” START Switch - This switch is used to transfer the UPS from static bypass to inverter during maintenance purposes. Transfers will lock-out if the bypass voltage is more than +10%,-10% of nominal.

*Uninterrupted switching is made at the time of synchronous operation. Switching is impossible at the time of asynchronous operation.

6.“INVERTER STOP” Switch - This switch is used to transfer the UPS from inverter to static bypass during maintenance purposes. Do not operate it under normal operation. Transfers will lock-out if the bypass voltage is more than +10%,-10% of nominal.

*Uninterrupted switching is made at the time of synchronous operation. Switching is impossible at the time of asynchronous operation.

7.“FAULT RESET” Switch (FOR SERVICE PERSONNEL ONLY) - This switch resets errors resulting from alarm conditions. (Do not operate this switch while inverter and converter are in operation.)

8.Maintenance (Set) Button (FOR SERVICE PERSONNEL ONLY) - This switch sets the UPS menu parameters.

9.“Test mode” Switch (FOR SERVICE PERSONNEL ONLY) - This switch changes system operation to the test-mode. (This switch should not be operated by personnel other than an Authorized Service Engineer).

10.“BOOT” Switch (FOR SERVICE PERSONNEL ONLY) - This switch boots the processor in the main control circuit resulting from alarm conditions. (Do not operate this switch while inverter and converter are in operation).
