Assembly and installation
The device must be installed on a plane surface only, in vertical
operating position. Loosen the cover screws (2) (see overview of the
device on page 5 to 7). and detach the upper part of the telephone (1).
If the optional accessory headset or a second earpiece is being
employed, attach the bracket (10) using two screws (11) to the rear
panel of the lower part of the telephone. (With the accessories named
before, the bracket and screws are in the scope of delivery. With all
accessories a cable gland is delivered.) Put four screws, having a head
diameter of 10 to 13 mm into the holes (20) and attach the lower part of
the telephone (3) to the wall or to a holder.
Installation differs depending on the type of telephone model. On the
telephone with factory equipped plastic cable entry, the telephone network
cable should be passed through the cable entry (4) and connected to
terminals 13 and 14 (A, B) in accordance with the connection diagram. Only
use cables with a sheath diameter of 5 to 9 mm because otherwise the IP66
enclosure protection rating may be compromised.
On the telephone with the M20x1.5 threaded opening or the 1/2” NPT
threaded opening, the customer is responsible for mounting a cable entry.
Follow the manufacturer’s instructions supplied with the cable entry
assembly. Only cable entries with EU type approval for IP66 enclosure
protection rating and -25°C ≤ Ta ≤ 60°C should be used and they should
provide a good seal and fit tightly to the cable. On this model (Protection
Class I), make sure the PE (protective earth) wiring is connected properly.
Corresponding connection points are provided and marked inside and
outside of the housing. The telephone network cable must be connected to
terminals 13 and 14 (A, B) as shown on the connection diagram. If a torque
of more than 20 Nm is used to tighten down the sealing rings of the cable
entry, then the side of the cable entry assembly nearest the housing should
be secured against rotating.
Connecting a second ringer (bell-shunt) (optional accessory)
Remove the sealing plug (5) and tighten the M20x1.5 cable gland
cap. Insert the wire of the second ringer and place it on the terminals
in accordance with the connection diagram. Only utilise wires which
have a sheath diameter of 5 to 9 mm because otherwise the IP66
housing protection standard is not guaranteed.
Connecting an external loudspeaker (optional accessory)
Remove the sealing plug (6) and tighten the M20x1.5 cable gland
cap. Insert the wire of the loudspeaker and place it on the terminals
11 and 12 (SPK+,SPK-) in accordance with the connection diagram.
Only utilise wires which have a sheath diameter of 5 to 9 mm
because otherwise the IP66 housing protection standard is not
guaranteed.
