Connecting The Cable Screening; Powering The Communication Server; 115/230 V Power Supply - Mitel 430 System Manual

4. 3. 2

Connecting the cable screening

When using shielded installation cables also use shielded RJ45 connectors. In this
way the shielding of the installation cables is automatically connected with the housing
of the communication server and therefore with the building earth.
Note
Connect the cable screens to one another at the splitting point only. Observe the tree structure
principle to prevent earth loops.

Powering the communication server

The communication server is powered as standard with 230 VAC or 115 VAC. To en-
sure that its operation is maintained even in the event of a mains outage, an external
uninterruptible power supply (UPS) must be used.
4. 4. 1

115/230 V power supply

The communication server is powered by the supplied power supply unit. The power
supply unit is connected to the mains using a two-pin standard power cable.
Hazard:
Hazard due to heat generation in the event of short-circuits. The mains power supply connec-
tion must be protected with 16 A maximum in countries with 230 V mains power (for instance in
Europe), and with 20 A maximum in countries with 115 V mains power (e.g. in North America).
