ABIHSOT 6 7 8 9 30 4. 3. 2 RS-232C The RS-232C serial communication interface is available via a DB9 female connector located on the rear of the UPS (see Section 9 for DB9 connector location). This interface allows control of the UPS from a personal computer running special Toshiba software. The computer and the UPS are connected through a serial RS-232C communication port. The available data from the UPS, via the RS-232C communication link is shown below.

This function can allow you to stop discharging the UPS batteries after an orderly system shutdown has been completed. The UPS can be programmed to turn OFF up to 8 minutes after the Shutdown command is given. This command can be cancelled before the specified time has elapsed by following the directions listed on the RS232 screen. An initial charge time of 24 hrs is necessary to obtain proper battery performance level before the unit is placed in operation. (***) At 6600-ft (2000 m) above sea level, output capacity should be derated by 3% (Consult factory for higher elevations). (****) Prolonged operation at this level requires derating of the maximum Operating Temperature to 35°C. ABIHSOT 35 6. 0 Operating the UPS 6. 1 6. 1. 1 Operating the UPS AC Input Mode (normal operation) The following illustration shows circuit power flow when the UPS is operating normally in the AC input mode. The converter of the UPS, including a boost chopper circuit, converts the AC input power to DC power. The boost chopper circuit maintains a constant voltage and provides current limiting for battery charging. It also supplies a DC voltage of the proper level to the inverter section. The inverter section generates a high quality sine wave output voltage. The UPS batteries always maintain a charge during normal UPS operation. Power Flow MCCB Isolating XFMR Converter Inverter Output Power Static Bypass Input Power Power flow in AC input mode for the 4200FA 75/80 kVA UPS 6. 1. 2 Bypass Mode If the UPS detects an overload or develops an internal fault, power flow is automatically switched from the main circuit of the UPS to the Bypass circuit. Power flow through the Bypass is shown in the following illustration. This changeover occurs automatically in less than 4 milliseconds. The switching period is not long enough to cause interruptions to occur in most loads.
