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 PLUS 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).
The Neutral is not through. Is necessary to put a label, as the following one, into the AC
input distribution box.
To guarantee UPS normal operation, before connecting devices to the UPS, please verify
that ground and neutral lines of the connected devices are not short circuited. See the
image below.
