INSTALLATION INSTRUCTION
Subject responsible
1 GENERAL
The exchange cabinet BDV 113 08 can be furnished
with Printed Board Assemblies (PBAs or boards) be-
longing to ERICSSON’s PBX-system ASB 150 02. The
desired system functions are made possible by means
of the appropriate boards and system programming.
The ASB 150 02 system can be expanded to a maxi-
mum of three exchange cabinets of type BDV 113 08.
The PBX can be powered either by a transformer unit,
a switched mode power supply, installed in the back of
the cabinet, or by an existing external 48 V DC-source.
After installation the PBX shall be made operational in
accordance with the stipulations that apply for system
ASB 150 02. See document START OF OPERATION
(1537-ASB 150 02). The cabinet is adapted for boards
fitted with brackets containing screws. Only boards
equipped with these brackets must be installed. These
screws must always be fastened to ensure a proper
ground connection.
Every cabinet’s board position could be used for arbi-
trary furnishing with boards belonging to PBX system
ASB 150 02 but the first position in the first cabinet
must be reserved for the CPU-D_.
Any lines connected to the PBX that are subjected to
excess voltage (transients) in conjunction with e.g.
lightning discharges must be equipped with excess
voltage protection, refer to figure: Line protection. The
excess voltage protection can not be installed inside a
BDV 113 08 cabinet but should be mounted in an inte-
grated or external MDF.
Special precautions must be taken for analogue exten-
sion lines that are leading outdoors to prevent the ana-
logue extension board’s secondary protection devices
from blowing in case of lightning.
In this case the extension line must have:
1 A protective resistor of 10 Ω/1W
(REN 195 42/1) connected in series
between cabinet and MDF
2 An overvoltage arrester (gas discharge
tube) for quenching surges to protective
ground should be installed on the network
side of the protective resistor
