5.2 Connectivity options
5.2.1 Remote SHUT DOWN (EPO)
The REMOTE SHUT DOWN must use a normally closed contact, which opens to operate the remote
shut down sequence. Usually the shutdown procedure is disabled and it should be activated by a
Hardware Code on “Setup Service” menu”. Please contact your distributor to enable this operation.
NOTE
THE UPS IS PROVIDED WITH AN “EMERCENCY BYPASS” WHICH IS
CONFIGURATION. IN THIS CASE THE EPO WILL BE AUTOMATICALLY
DISABLED AND MUST BE ACHIEVED IN THE BUILDING/FACILITY. THE
FACIULITY EPO MUST OPEN THE BYPASS PATH.
The remote shutdown terminals are on the input interfaces X1, pin 7 and 8.
In order to allow removal, maintenance or testing of any remote shut down facility without disturbing
the normal operation of the UPS, it is recommended that a terminal block, be installed between the
UPS and the emergency stop button, as shown in Fig. 13. Use a screened cable with 1 pair (section of
wires can be chosen from 0.5 to 1.5mm2) and maximum length of 100 m. The Switch must be a
normally closed (dry contact).

5.2.2 Generator on facilities
The Generator ON facility must use a normally open contact that closes to indicate that a generator is
running and supplying input power to UPS. The remote Generator ON terminals are on the input
interfaces X1, pin 1 and 2.
When used, this facility disables the UPS static bypass and prevents the UPS from transferring the load
on to the generator power supply and/or block the battery charger during the time the UPS is supplied
from the genset.
