Installation Manual

Chapter 4
It is connected via the mains socket at the rear of the platform:
- UPS Power: use the mains cable provided with the Alcatel-Lucent OmniPCX Office
Communication Server module.
- UPS Connection - module: use the cable supplied with the UPS
For an installation using 3 Alcatel-Lucent OmniPCX Office Communication Server modules, 2
UPSs are required: one feeds two of the modules, the other feeds the third module.
4.3.1.5 Mains Connection - Ground Connection
4.3.1.5.1 OmniPCX Office RCE Small, Medium, Large
The connection can be made using electrical installations of the following type:
- TT (local ground for each piece of equipment).
- TN (common ground for all equipment).
- IT with inter-phase voltage of 230 V; only possible in Norway.
Mains socket fuse: T2.5 AH / 250 V (delayed action, high cutout).
So as not to compromise the fire protection feature, replace fuses with the same
type of fuse having the same nominal characteristics.
For continued protection against risk of fire, replace only with same type and
rating of fuse.
The system is delivered with a 3 conductor cable (length: 3 m) to connect to the mains socket.
Permanent Ground
It is essential to connect the system permanently to ground due to leakage currents greater
than 3.5 mA over the whole line access (safety constraint CEI60950 ed.03). To do this, use the
ground wire of minimum section 4 mm 2 provided and connect it to the tag at the rear of the unit
(left hand side).
For performance and safety reasons, the system must always be connected to the
ground. The ground must be connected prior to all the other connections.
