3 Communication

Warning: Do not use the paralleling cable that came with the UPS system for these procedures. Use a RS232 cable.

3.01 RS232 Port

The UPS provides a RS232 port in one D-sub 9 female connector. This RS232 port performs the following functions:

3.1) Sets EEPROM on the NH-M board

3.2) Sets Output Dry Contact status

3.3) Upgrades the system board’s ﬁrmware

3.4) Upgrades the power module’s DSP ﬁrmware

3.5) Downloads the event log of the UPS

Use the straight through serial connection to communicate with the RS232 port. The pin assignment of the RS232 port D-sub 9 female connector is deﬁned as follows:

Figure 3.01a RS232 Pin Assignment

Pin 2: PC receives line RS-232 data from UPS.

Pin 3: PC transmits line RS-232 data to UPS.

Pin 5: Signal ground.

3.02 Emergency Power Off (EPO)

Fig 3.02a Front Control Panel

The EPO button on the front control panel (Figure 3.02a) turns the UPS system’s output OFF and also disables its bypass output. If the UPS system is in battery backup mode when the EPO button is activated:

•Main output and bypass output are turned off, the alarm sounds, fans shut down after approximately one minute, and control circuitry remains active.

•Pressing the EPO button again turns off the UPS system completely, including the alarm and control circuit. Press the ON button for three sec- onds to restart the UPS system.

If the UPS system is in online (normal) mode when the EPO button is activated:

•Main output and bypass output are turned off, the alarm sounds, fans and control circuitry remain active.

•Pressing the EPO button again turns off the alarm and places the UPS system in auto bypass mode. Press the ON button for three seconds to return the UPS system to online (normal) mode.
