In the absence of an input separation transformer, the neutral coming from the power mains is connected to the output neutral
of the UPS. The system neutral connectivity is not modified:
THE DISTRIBUTINO SYSTEM POWERING THE UPS IS NOT MODIFIED BY THE UPS
ATTENTION: ensure proper connection to the input neutral as failure to do so can damage the
UPS.
Neutral connectivity is modified only if an isolation transformer is present or when the UPS operates with neutral
disconnected upstream.
When operating with mains power present, a differential switch inserted in the input can intervene since the output circuit is not
isolated from the input circuit. In any case, it is always possible to insert more differential switches in the output, possibly
coordinated with those present in the input.
The differential switch set upstream must have the following characteristics:
suitable differential current for the sum of UPS + load; it is advisable to keep an adequate margin to prevent
inopportune interventions (300mA recommended)*
type B
delay higher than or equal to 0.1s
* The load dispersion current is added to that of the UPS on the ground protection conductor

R.E.P.O.

This isolated input can be used to remotely switch off the UPS in case of emergency.
The UPS is supplied with "Remote Emergency Power Off" (R.E.P.O.) terminals short-circuited by a jumper (see "Front UPS
Views"). To manage emergency shutdown, replace the jumper with the selected normally closed stop device contact. Connect
using double insulation wiring.
In case of an emergency, the stop device opens the R.E.P.O. control and the UPS goes into stand-by mode (all power stages
off) and the load is completely disconnected.
The R.E.P.O. circuit is self-powered with SELV circuits. Therefore, an external voltage supply is not required. When closed
(normal condition), a current of 15mA max circulates.
