2. Capacity of output dry contact ports J14 and J15: 24Vdc, 0.5A.
3. Capacity of output dry contact ports J16 and J17: 250Vac, 5A.
4. If REPO is required: Pin6 and Pin8 are reserved, and Pin2 and Pin4 of J14 are shorted before delivery;
If Normally Closed switch is configured as REPO, remove the shorting cable between Pin2 and Pin4,
and then adopt the shielded cable to connect Pin2 and Pin4 with the switch;
If Normally Open switch is configured as REPO, reserve the shorting cable between Pin2 and Pin4, and
then adopt the shielded cable to connect Pin6 and Pin8 with the switch.
5. If configurable input dry contact is configured as ‘Start Battery Maintenance Self-check’ or ‘Stop
Battery Maintenance Self-check’ or ‘Alarm Cleared’, the rising edge triggering will be effective; if
configurable input dry contact is configured as other functions, the level triggering will be effective.
NOTE: Activating the UPS EPO will close the rectifier, inverter, bypass and battery, but does not
disconnect the UPS mains input inside. If you wish to disconnect the UPS completely, it is also
necessary to open the internal input switch and unplug the battery terminals when activating the EPO.
In the event of an emergency, trigger the REPO switch (supplied and installed by the user) in order to
shut down the rectifier and inverter, and switch the UPS off. Under normal conditions, the REPO switch
cannot be used to isolate the UPS from the mains input power. If an electronically controlled circuit breaker
function is installed at the UPS input, the REPO switch can be used to trip this breaker, thus cutting off
the UPS mains input power. The position of the REPO switch is shown in Figure 7-7 , and the REPO cable
connection is shown in Figure 7-8 and Figure 7-9 .
