i
Lead the protective earth wire laterally out of the bore (see illustration)! If this is not done,
the antenna cannot be pushed into the correct position.
Fasten the antenna by
tightening the cable gland (see
illustration.)
i
While tightening, hold the antenna from the inside against the cable gland. Otherwise the
antenna will be pushed into the housing during tightening.
Loosen the M4x6 pan headed screw with which
the earthing lead is retained between housing
cover and housing base.
Reattach the earth lead of the antenna together
with the earth between housing cover and base at
the illustrated screw post (see illustration).
i
Always fit the earth lead between cover and base exactly as illustrated, as the eye on the
circuit board side will otherwise interfere with housing closure.
CAUTION!
Equipment damage through incorrect connection of the GSM antenna!
If the connection of the GSM antenna is not properly made at the GSM / GPRS modem socket, this can
suffer damage.
Any mechanical strain induced by the cable must be prevented at all costs.
Attach the antenna cable with the aid of the light gray plastic
cable grip installed at the factory. For this reason the length
of cable between the outlet of the cable grip and the end of
the antenna plug should be approx. 62 mm (see picture on
the right hand side), and the shrunk-on tubing should be
moved along the antenna cable in such a way that after
clamping it is placed approximately at the center of the grip.
Connect the GSM antenna cable with the modem.
i
In particular, make sure that the antenna plug does not lie skew in the bushing and that it is
not stretched any longer by rotary and pull-off forces respectively.
There is a risk that the socket could detach from the modem!
i
The cable grip should be carefully pushed
upwards during the installation of the antenna
cable. There is always the risk of permanent
damage to the cable grip!
