Grounding
To comply with EN 60950, the equipment must be connected to a safety
grounding point via a permanent link. Grounding points are located on the product
for this purpose. Always connect the ground cable before fitting other cables. The
product must remain grounded continuously unless all connections to the power
supply and data network are all removed.
If equipment is grounded through a cabinet or rack, make sure it is done so
properly according to the installation instructions.
Power Supply Connection
The equipment is designed to be powered from a -48 V DC supply. Power
connections and installation of associated wiring must be carried out by a suitably
qualified technician.
Only devices that comply with all relevant national safety requirements should be
connected to the unit’s power supply inlets. Other usage will invalidate any
approval given to this equipment.
Connection of this equipment to devices that are not marked with all relevant
national safety requirements may produce hazardous conditions on the network.
When the power supply is obtained by a rectifier/safety isolation transformer, the
supply must meet the requirements of EN 60950 providing double/reinforced
insulation between hazardous voltages and SELV/TNV circuits. Any battery must
be separated from hazardous voltages by reinforced insulation.
Indirect Connection
Before indirectly connecting any equipment to another device through a shared
power supply, ALWAYS seek advice from a competent engineer.
Devices that are not marked according to the relevant national safety standards
may produce hazardous conditions on the network.
