5.6.3 Emergency power-off
An external Emergency Power-Off (EPO) switch can be installed by the customer to enable
immediate shutdown of the UPS. Once switched off by the EPO, the POWER+ must be restarted
manually.
The UPS has two terminals marked "EPO" for connection of an EPO switch (Figure 32). Use of a
large mushroom-type N.O. (normally open) pushbutton rated for not less than 1 A / 24 Vdc is
recommended. Verify continuity of the switch at its connection points before installing.
In the event that the POWER+ UPS is used in a computer room, installation of the EPO
switch is mandatory. It is also required in this case that activating the EPO switch should
disconnect the dc power supply from the batteries. The battery CB terminals on the POWER+
(Figure 19) must be connected to the trip coil terminals on the battery cabinet (Figure 32).
To restart the UPS following use of the EPO, turn off all input circuit breakers (rectifier ac input,
bypass ac input, battery) and then start the POWER+ as normal (see section 6 on page 57).
