Commissioning
Note:
The communication converter is delivered with the jumper settings “X.21”
and “64 kBit/s”.
Open the communication converter
Disconnect the auxiliary supply voltage from both poles.
Open the communication converter. To open the device, you must undo all six cover
screws with a screwdriver.
Configuring the communication converter
The communication converter is configured via jumpers. The slots of the jumpers can be
seen in Figure 19. The factory setting is shown.
Selecting the interface:
Set the jumper X30 in accordance with the interface type selected for communication:
X30
in position
1–2
for interface
X.21
,
X30
in position
2–3
for interface
G.703.1
.
Selecting the transmission speed:
With the jumpers for X20, X22, X24 and X26, set the transmission speed necessary for
communication (see table 2). Only one slot can be occupied at any one time.
Note:
In the operating mode
G.703.1
, the jumper must be set to
X20
, since there is only
one transmission rate for it (64 kBit/s).
The transmission rate parameterized in the
protection device for the active interface and the corresponding jumper position
have to correspond to each other
.
DANGER!
Before opening the communication converter, it is absolutely ne-
cessary to isolate it from the auxiliary supply voltage at all poles!
Energized parts pose a potentially lethal hazard!
