10.1 Introduction
The Conceptpower DPA 500 is provided with the following accessories:
• REMOTE SHUT DOWN (EPO)
• GENERATOR OPERATION
• SOFTWARE FOR REMOTE COMMAND SHUTDOWN AND MONITORING
• SNMP INTERFACES FOR NETWORK MANAGEMENT AND REMOTE MONITORING
10.2 Remote Shutdown (EPO)
The REMOTE SHUT DOWN must use a normally closed contact, which opens to operate the remote shutdown 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.
THE UPS IS PROVIDED WITH AN "EMERCENCY BYPASS" WHICH IS AUTOMATICALLY
ENABLED IN CASE OF A SINGLE MODULE 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 on terminal port X3/3.. X3/4 is located on the Conceptpower DPA 500 Cabinet.
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, with linking facilities, be installed between the UPS and the stop button.

10.3 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. It is located at the bottom of the Conceptpower DPA 500 Cabinet.
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.
