Safety notes ¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢
Pay attention to the safety notes
- before installing or removing a mod-
ule,
- before connecting or disconnecting a
connecting lead
1. Remove the telephone system's 230
V mains plug from the socket.
2. Remove the Western plugs of all ex-
ternal ISDN basic accesses from the
telephone system, the network termi-
nator (NT) or the S0 bus.
3. Touch the metal shield of the PC/
printer socket on the bottom of the
telephone system briefly with your
finger. This will discharge any possible
electro static charges, thus protecting
the telephone system’s lectrostatically
sensitive components.
Installing a module
- Insert the module vertically, with the
large connector strip pointing upwards,
into the top hand bottom guide slits of
one slot.
Slot X=0 (outside right) must be used for
the connection module. The connection
module must not be plugged into any
other slot as otherwise a connector will
be destroyed.
You can choose slots X=1 to 4 freely for
all further modules.
- Carefully push the module down until
the connectors engage and the latching
lug of the module latches into the lock.
- Pull the adhesive label showing the
module’s connections off the
information sheet (included with the
Installing and replacing modules ¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢
module packaging).
- Stick the adhesive label over the
module’s slot on the housing.
Replacing a module
- Undo the module’s connecting leads.
Mark the connecting leads clearly to
avoid confusion on reconnection.
- Move the module extractor (bolt)
carefully along next to the module and
approxima-tely in the center of the
module towards the back. Turn the
module extractor so that the hook hooks
underneath the module.
- Press the lock upwards until the
module’s latching lug is free. Carefully
pull the module out towards you using
the module extractor.
Marking connecting leads ¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢
Mark connecting leads clearly to avoid
confusion when expanding the telephone
system or when reconnecting leads. Use
the included marking system to mark the
connecting leads. It consists of:
- Plastic comb element with 20 strips for
inscription
- 20 transparent sleeves for securing
- Mark the strips with a pencil or a fibre
tip pen.
- Break the trips off the comb element.
- Insert the strips in the small chambers
of the sleeves.
- Slide the sleeves with the large
chambers onto the ends of leads.
