RT installation
WARNING
The IDU chassis must be solidly bonded to a
low–impedance ground (earth) source.
To avoid the risk of electric shock and/or
equipment damage, do not apply power to
the IDU chassis without a ground reference.
CAUTION
If the ODU and lightening arrestor are not
connected to the IFL, do not power on the
IDU chassis without first making sure the
IFL is not connected to the IDU chassis.
Failure to observe this instruction could
result in damage to the equipment.
To connect ac power:
1. Measure the voltage level of the power source to make
sure it can accommodate the total IDU and ODU power
requirements.
(The IDU supplies power to the ODU through the IFL.)
If the voltage level cannot accommodate the IDU and ODU,
the power source must be upgraded before you can proceed.
2. Connect the power cable to the IEC–320–C13 connector on
the power supply.
3. Route and secure the cable to avoid physical damage.
4. Connect the plug end of the cable to a dedicated ac power
source.
Important: In the United States, ac–power IDU chassis
must be connected to a dedicated power circuit with a
15–ampere single–pole breaker. The circuit must not
include unrelated equipment.
