Connection of "Media Contacts 11" standard auxiliary circuits
See figure 26 below for information on
connecting the auxiliary circuits to the
three connectors on the "Media
Contacts 11" board in the Galaxy PW
UPS cubicle.
See the position of this board, marked
"O" in figures 12 to 14.

;
◗
the male connectors that fit the female
connectors on the board (XR2 to XR5)
are supplied;
◗
the contacts are volt-free and are
shown in the diagram under the
following conditions: UPS on, contact at
rest;
◗
contact breaking capacity: 250 V, 5 A.
Connection to battery
circuit breaker "QF1"
◗
connect the cable from connector
XR3 (pins 2 to 8) on the "Media
Contacts 11" board in the UPS cubicle
to connector XR1 in the battery cubicle
containing battery circuit breaker QF1.
Emergency power off
The UPS emergency shutdown function
is generally wired to a "mushroom-
head" type emergency-off button.
Important:
In the case of a complex installation
with a number of units, there should be
only one emergency shutdown
pushbutton and this pushbutton must
interrupt all the active conductors of all
the units.
For the same reason, it is essential for
the pushbutton to open the upstream
protective circuit breakers on the
normal and bypass inputs.
Each type of unit (single UPS, parallel
UPS, frequency converter) must have
an independent, volt-free contact
connected to the emergency shutdown
pushbutton. This pushbutton must
therefore have as many contacts as
there are units in the installation, as
well as the contact or contacts required
to open the upstream protective circuit
breakers on the normal and bypass
inputs. The emergency shutdown
pushbutton turns off the rectifier/
chargers and inverters, opens the
battery circuit breakers and activates a
contact on the "Media Contacts 11"
board (terminals 1 to 3 on connector
XR4). The emergency shutdown signal
will be cleared when the emergency
shutdown pushbutton contact has been
reset.
