Emergency power-off
An external Emergency Power-Off (EPO) switch can be installed by the customer to enable immediate
shutdown of the UPS’s output. After being shut down by the EPO function the
Power+ Premium 60
must
be restarted as described below.
The UPS has two terminals marked "EPO" for connection of an EPO switch (see Figure 19). 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.
