9.0 SHUT-DOWN
1. Close down the load in an orderly manner.
2. Push the (inverter shutdown) button for more than 2 seconds.
3. Turn the main switch to OFF.
Note: If the electricity supply to the site is switched off outside normal working hours, the EDP70 PLUS should be shut
down each evening, by either using the shutdown procedure or wiring in the Emergency Power Off (EPO) function,
see figures 20, 23 or 26 (depending on the UPS size).
This will prevent the battery from discharging.
If, on the other hand, the supply to the site is continuous, the EDP70 PLUS should be operated 24 hours a day.
9.1 Installing the EPO
To wire the EPO, open the link between terminal boards 1 and 2 and connect a signal switch, having the characteristics
of an emergency button, closed under normal operating conditons and held open mechanically when operated: when the
switch is enabled, the inverter and rectifier will stop, the battery relay will be opened and the load will be de-energized
To ensure that the EPO functions correctly, the signal should remain active for a period > 400 msec.
