Connecting The Earthing - Auerswald COMpact 4000 Instructions Manual

• Protect the PBX from dirt, excessive dust, condensation, caustic liquids, and steam.
Requirements:
• 3 screws and 3 dowels
• Connections close to the installation site:
– Freely accessible Schuko socket
– Wall socket or NT provided by the network provider; if the wall socket/NT is relatively far
away from the PBX, permanent cabling must first be laid between the devices
– Grounding conductor (potential compensation bar of the house installation or protective
earth conductor)
1. Mark and drill the two upper mounting holes at a distance of 232 mm and insert dowels
into the holes.
Note: Also note the casing dimensions 334 mm x 331 mm x 94.5 mm. There should be a
distance of at least 60 mm between the upper mounting bores and any parts above them.
A drilling template can be found on the Internet.
2. Screw in the two upper screws far enough so that the screw head is about 5 mm away
from the wall.
3. Mount the PBX on the screws, then slide the PBX on the wall downwards until the screws
hit the stopper.
4. Place a mark where the third mounting hole is to be drilled into the wall.
5. Remove the PBX from the wall.
6. Drill the mounting hole and insert a dowel into the hole.
7. Mount the PBX on the screws again, then slide the PBX on the wall downwards until the
screws hit the stopper.
8. Secure the PBX by tightening the third screw.

Connecting the Earthing

Warning: Touching voltage-carrying conductors or telephone connections can
cause life-threatening electric shocks. The PBX contains hazardous voltages, even
outside of the power supply unit (for instance ringer voltages). Work on active,
contact-hazardous parts is only permitted after creating a voltage-free state. Working close
to active parts is only permitted if these parts are voltage-free or are protected against
direct contact.
• Disconnect terminal devices from the PBX. No terminal devices should be connected
during the installation of the earthing. Connected terminals may feed-in currents which
might cause electrical shocks.
• Pull out the PBX's power plug. Also disconnect the device from additional power sources
(e. g. UPS, if installed).
• Wait at least 3 minutes for the discharge of any capacitor in the device after
disconnecting it from the main power supply.
