Output Voltage Selection Switch Information
The voltage selection switch is in the upper left corner next to the
communication port on the back of the UPS. The table next to
the switch tells what output voltages are available.
Set the voltage selection switch to the positions shown for the
inverter output voltage you want.
Important Note: When the UPS is in Bypass Mode, the
voltage selection switches do NOT control the output voltage
(For U models that are hardwired, make sure the UPS and
its AC line input breaker are off. If you have an optional
bypass switch, make sure it is turned to "Bypass" or "Off".
Remember that In "Maintenance" or "Bypass", the
voltageelection switches do not control the output voltage.)

RS232 Port Information
The 610 UPS uses a DB9 communications connector on the rear
panel. From this connector you can access opto-coupled outputs
indicating mains failure or low battery. The contact ratings are
30VDC at 10 mA.
A. RS232 Receive Data See Note 1
B. RS232 Transmit Data
C. RS232 Ground
D. Normally Open - Closes on Input Mains Failure.
E. Normally Closed - Opens on Input Mains Failure.
F. Normally Open - Closes on Low Battery

Note 1: Remote shutdown is available in battery
mode only, with no line (mains) applied. Keeping
pin 6 at +5 to +12 VDC for one second will turn off
the UPS inverter.
