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
(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.
For performance and safety reasons, the whole system must always be coupled
to the ground. The ground must be connected before any other connections.
The ground protection connection terminal must always be connected to the
ground. Protective grounding terminal shall be permanently connected to the ground.
4.3.1.5.2 OmniPCX Office RCE Compact
Alcatel-Lucent OmniPCX Office Compact Edition
is powered by an external power supply unit (100/240V). It is connected via a jack plug at the
front of the module (right hand side).
Remarks:
- A mains cable is not supplied with the module. It must be ordered separately.
- For a more secure configuration, an AC/DC power supply, including a backup battery, can be pur-
chased as an optional extra.
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 2.5 mm
the tag on the metal bottom of the unit (right hand side).
