Emergency Power Off - Integra Xmart OPTIMA T10 15K User Manual

14. EMERGENCY POWER OFF

UPS counts on a 2 terminals port as EPO (Emergency Power Off) input. Refer to image below for details.
These terminals are connected in factory (Closed Contact) to avoid the emergency stop status.
For connecting an Emergency Stop Switch to UPS EPO port, remove the original jumper and connect an appropriate switch (Normally Closed
Contact). This must be done with UPS turned off. Otherwise, when removing the EPO Jumper, UPS will turn-off immediately. This kind of switch is
not included in the UPS, if required, switch must be purchased separately.
When switch is opened, UPS executes immediately the emergency power off function.
EPO function immediate result:
▪
- Rectifier and Inverter are stopped.
- UPS Internal STATIC BYPASS SWITCH opens leaving UPS output unpowered. (Output Off)
If the UPS on which EPO function is activated is in parallel system with other UPS, the emergency stop will act on all UPS in the
▪
system, turning off the system completely.
