Drop cable tester
The drop cable tester must NEVER be used at the ODU end connected to power from
the PoE power supply. It must only be used at the bottom of the mast with a
multimeter. This is because the PoE power supply 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.
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.
The minimum separation distances for each frequency variant are specified in
Calculated distances and power compliance margins
