AUX.OUTPUT
External control
terminal block
These are terminals for connecting the optional outlet box and for use as EPO terminals
*1
.
Connecting an outlet box to the UPS provides three output lines: OUTPUT0, 1, and 2. You can set
ON/OFF delay times for OUTPUT1 and 2, allowing you to control system start and stop. This
function is called “Output line control”.
*1
: EPO is an abbreviation of Emergency Power Off.
External view AUX.OUTPUT terminal names
AUX.OUTPUT (OUTPUT) terminals 1 to 4: Outlet box connection terminals
Connect the optional outlet box for control of UPS output lines. In the user settings
menu, you can set ON/OFF delay times for OUTPUT1 and OUTPUT2 of the outlet box,
allowing you to start and stop connected loads in sequence.
For details, see §18.3 “Outlet Box”.
AUX.OUTPUT (EPO) terminals 5 and 6: EPO terminals
Connect these to the terminals of a switch or other device to enable Emergency Power
Off of UPS output.
When the switch is pressed in an emergency, the EPO terminals are shorted and UPS
output stops. For details, see §18.7 “Connecting the Emergency Power Off (EPO)
Terminals”.
The switch to connect to the EPO terminals is not provided as a standard option for the
UPS. Check the following specifications, and use a switch that complies with the
specifications, or connect to compliant contacts on your system.
EPO terminal specifications
•
Circuit voltage: DC+5V (terminal 6 is - (minus) polarity)
•
Current when shorted: Approx. 10 mA
•
EPO operating conditions: Short-circuit terminals 5-6 for 0.2 seconds or longer
•
EPO terminals: One-touch terminal block (compatible wires: AWG26 to 20)
When using a transistor or other semiconductor
switch, connect terminal 6 to - (minus) polarity,
as shown in the figure.
(Connection direction is not specified for nonpolar
switches.)
