SWITCH
Figure 5 – EPO (Emergency Power OFF)
If the switch is CLOSED the UPS works normally; if, on the contrary, the switch becomes
OPEN then the UPS Output turns OFF immediately.
To switch the UPS Output ON again after an EPO, it is necessary to close again the EPO switch.
The EPO terminals are isolated and do not need an external feeding Voltage.

Electrical Installation
The electrical installation has to be done by qualified personnel. Follow all the Safety
Standards (CEI Standards in Italy or IEEE elsewhere) for the Input/Output connections
and for the right selection of Input/Output cables.
For safety we recommend using external circuit breakers between Input mains and UPS
AC Input line and between UPS Output lines and the loads. The circuit breakers should
be qualified with leakage current protective function (leakage current < 30 mA).
For the Input/Output connections use ONLY the included power cables or cables with
the same power ratings.
TECNOWARE declines any responsibility if this warning is disregarded.
The EVO DSP MM models are made of a single unit design that contains the electronic parts and batteries.
Before starting the installation procedure, be sure that:
1. The AC Input Voltage for the UPS has been removed.
2. The UPS is completely OFF (only if graphic LCD panel is OFF).
