1. Capacity of input dry contact port J13: 12 Vdc, 20 mA.
2. Capacity of output dry contact ports J14 and J15: 24 Vdc, 0.5 A.
3. Capacity of output dry contact ports J16 and J17: 250 Vac, 5 A.
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.
• 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 turn off the UPS. 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 7-6 , and the REPO cable connection is shown in Figure 7-7
and Figure 7-8 .
