INSTALLATION
1
If the system is already installed and
operating, inform the customer that your
work is going to shut down his exchange.
2
Unscrew and remove the front cover from
the exchange cabinet and note the
position and connections of all boards.
3
Lower the bottom plate and switch off the
power switch. Then remove the 36 VAC
power cable, entering the bottom of the
cabinet (E), coming from the transformer
or similar equipment.
4
Note the position of the boards and re-
move them all. Position the BML unit so
that the connectors are facing the bottom
of the cabinet and the four mounting holes
facing the rear of the cabinet.
5
Slide the BML unit in at the rear of the
cabinet and secure it with the supplied
four screws. For safety reasons on class I
units verify that the screws are tightened
to the cabinet as they ensure the
connection to protective earth.
6
Connect the power cord to the BML unit
and plug into mains. Connect cable TRE
990 113/0850 to one of the two four-pin
outlets (C or D) on the BML unit. It is good
practice to measure the -48 volt (-54 volt)
before installing the rest of the equipment.
7
Connect the other end with the flat-pin
connectors (E) on the bottom of the
cabinet. This is polarity independent.
8
Re-install all boards according to your
notes of the initial configuration.
9
If you just had to install the BML 351 013
with no back up battery take the 6-pin plug
delivered with the BML unit. Plug it into
position (A) to prevent ESD discharges
directly to the connector. Then switch on
the cabinet and start up the exchange
(see under 5.4). Otherwise continue with
the installation of the appropriate battery
back up.
5.1
Installing the integrated battery
unit BKB 201 001
1
Mount the integrated battery unit with its
left frame, sliding into slot 6 of the cabinet.
Set the circuit breaker to off position.
2
Plug the cable coming from the battery
unit to the six-pin outlet (A) on the BML
unit. Note that as soon as this cable is
plugged in, and the circuit breaker is
turned on, there are 48 V present in the
system. Continue with 5.3 or 5.4.
5.2
Installing the battery cabinet
BKB 201 002
1
The battery cabinet should be located in
the leftmost position on the wall.
MAKE SURE THE CABINET IS 100%
SECURED TO THE WALL, SINCE THE
BATTERIES ARE VERY HEAVY.
2
Drill holes (4) and mount the wall bracket
SXA 112 4406 on the wall.
Place the battery cabinet on the bracket.
Tighten the 2 screws at the bottom of the
cabinet to secure it to the wall.
3
Set the circuit breaker to off position.
Mount the four batteries in the battery
cabinet. Interconnect the batteries with
the supplied cables. Then connect the
grey wire with the negative terminal and
the red wire with the positive.
WARNING: TAKE CARE WHEN USING
METAL NON-INSULATED TOOLS AS
THE BATTERIES DELIVER HIGH
SHORT CIRCUIT CURRENTS.
4
Use cable TRE 990 113/0850 to connect
the outlets (C or D) of the BML unit with
the connectors (E) on the bottom of the
exchange cabinet(s). This is polarity
independent.
5
Connect the cable coming from the
battery cabinet to the outlet (A) on the
BML unit.
Note that as soon as cable A is plugged in
and the circuit breaker is on, there are
