INSTALLATION AND ACTIVATION

6.1 Introduction
6.1.1 Security guidelines
6.1.1.1 Staff authorisation
Only qualified staff may work on the iPBX.
The installer must be aware of the possible electrical hazards to which they may be
exposed.
It is essential to take every precaution necessary for people's safety.
6.1.1.2 Safety
The iPBXs are powered up by the 230 V or 115 V, 50 Hz or 60 Hz mains or an optional
external battery.
The power supply module is protected by fuses located on the mains socket.
6.2 Operations concerning a new installation
There are several types of operations on a new installation site:
Installation and Maintenance Manual - Aastra 5000
Installation and activation
The iPBX is grounded for safety reasons and this connection must be made
before any others (see Figure 3.1 in Section 3 for the cabinets' earth connection.
Safety of energy distribution
Apply the usual precautions relating to mains power supply.
In case of danger, disconnect the power supply cable.
High leakage currents
In the event of a power line fault near telephone lines, service technicians must be
aware of the possibility of high leakage currents on metal system surfaces.
Leakage currents normally flow safely through the power cable to protective ground.
Isolate the telephone network lines before any intervention on the iPBX.
Lightning overvoltages
Transient overvoltages due to lightning can be conveyed by the supply cables and
telephone lines of the installation:
• The electrical power supply installation of the room must be protected against
lightning-generated overvoltages coming from the power supply network.
• The telephone installation must be protected against lightning-generated
overvoltages by inserting protection modules between the PSTN and the
distribution frame.
