9.2 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.
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.
NOTE
The remote shutdown on terminal port X3/3.. X3/4 is located on the CONCEPTPOWER DPA 500
frame.
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.
1. 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.
