Overview
The 1642 AM and 1643 AMS units can be powered as follows:
•
DC
•
AC
Electrical safety
The installation must be compliant with IEC 60950–Ed3, 1999-04.
The equipment must be grounded (connected to protective earth) (Class I equipment).
DC power supply
Each equipment must be fitted when the equipment is installed, with an external,
marked and easily-identifiable protection device of 3 A maximum.
The equipment must be supplied with a Safety Extra-Low Voltage (SELV) of –48 V
and the positive terminal of this source correctly connected to the protective earth.
The equipment can also be connected to a Telecommunication Network Voltage (TNV)
of –24 V to –60 V. No specific requirements are necessary for this type of source.
The user interfaces are of the SELV type and must only be connected to circuits with
the same type of interface.
The following power range must be observed: –18 VDC ... –72 VDC.
AC power supply
An external AC power distribution system classified IT cannot be used. (For IT
classification, see: IEC 60950–Ed3, 1999-04, Annex V: Power system isolated from
earth or one point connected to earth through an impedance and direct electrical
connection of the equipment to earth).
An external protection device is not necessary: the building installation is considered as
providing short-circuit backup protection (IEC 60950–Ed3, 1999-04, paragraph 2.7.3).
The user interfaces are of the SELV type and must only be connected to circuits with
the same type of interface.
The following power range must be observed: 90 VAC ... 264 VAC.
Protection against short-circuits
Important! Ensure that the 1642 AM and 1643 AMS units have reached room
temperature and are dry before taking them into operation.
