48 V present in the system if the switch is
turned on. Continue with 5.3 or 5.4.
5.3
Alarm connections
ASB 150 01
This feature is not applicable for the ASB 150 01. To
prevent electrostatic discharges (ESD) directly to the
alarm connector pins use the enclosed plastic 2-pin
plug and plug it into output B when the alarm feature is
not used.
ASB 150 02
The alarm output which is activated by a mains power
failure in the BML 351 013, consists of a closing relay
contact on output B (see figure 1)
1
Connect the power supply alarm cable
TRE 990 111/0400 to the two-pin outlet
(B) on the BML unit, and the other end to
one of the inputs (H or I) on the specific
battery units.
2
Connect the free end of the alarm cable
TRE990 112/2000 to the MDF connector
block (YELLOW to a4 and BLUE to b4).
Connect the other end to the remaining
two-pin input connector (H or I) on the
battery unit.
To prevent electrostatic discharges (ESD) directly to
the alarm connector pins use the enclosed plastic 2-
pin plug and plug it into output B when the alarm
feature is not used.
5.4
Start-up of the exchange
1
Turn on the circuit breaker and switch on
the power in the cabinet. Observe that the
system starts up correctly. If this is a new
installation, start up the system according
to the document START OF OPERATION
(1537-ASB 150 02 Uen).
2
RASC provides the facility for measuring
the secondary voltages. Use this feature
to check the values of the -48V, +5V and +/
- 12V in the system for proper operation.
3
Raise the bottom plate, replace the front
cover and tighten the two screws at the
bottom of the front cover.
4
Remove all excess material and inform the
customer that the system is back in
operation.
5.5
Single battery cabinet with two
battery chargers
System configurations having 2 cabinets and 2 charg-
ers installed can be switched to just one battery cabi-
net if the additional cabinet has a power consumption
of less than 60 W. This restriction is made to achieve a
sufficient back up time. Use the adapter cable
TSR BS 101 08 and the alarm adapter cable
TSR BS 101 09. If this load restriction cannot be ful-
filled two chargers and two battery cabinets are neces-
sary. If the distance between cabinet and output (C) or
(D) on the charger exceeds 85 cm use 1,5 m cable
TRE 990 113/1500.
NOTE:
Due to battery capacity reasons this
applies only to the battery cabinet.
