Powering down before servicing
Always power down and unplug the equipment before servicing.
Lightning protection unit (LPU)
Do not remove the LPU printed circuit board when the LPU is connected to the power
supply, as high voltages are present.
Drop cable tester
The drop cable tester must NEVER be used at the ODU end connected to power from
the PIDU. It must only be used at the bottom of the mast with a multimeter. This is
because the PIDU voltage exceeds the limit allowed in some countries for safe handling
in wet conditions and therefore may create a safety hazard.
Primary disconnect device
The main power supply is the primary disconnect device.
External cables
Safety may be compromised if outdoor rated cables are not used for connections that
will be exposed to the outdoor environment.
Grounding PTP-SYNC
In order to meet the safety requirements for deployment in Australia and New Zealand
(AS/NZS 60950-1), the PTP-SYNC unit, if deployed, must be grounded to a Protective
Ground in accordance with Local Electrical Regulations.
RF exposure near the antenna
Strong radio frequency (RF) fields will be present close to the antenna when the
transmitter is on. Always turn off the power to the ODU before undertaking
maintenance activities in front of the antenna.
Minimum separation distances
Install the ODUs so as to provide and maintain the minimum separation distances from
all persons. For minimum separation distances, see the
PTP 500 and PTP 300 Series
