5.2

Connecting the Flexbus cable

A clamp-type (watertight) straight TNC connector fitted into, for example, RG−
223 cable can be used to connect the IU and the OU. Leave the cable slack enough
to allow the outdoor unit to be turned during the alignment. It is advisable to label
the cables (for example with the hop ID) in order to facilitate identification later.
In case the cables are completed on site, protect the connectors from water with
adhesive tape or shrink-on wrapping. The ready-made cables have a shrink-wrap
protection.
Caution
If the cable is already connected to the indoor unit, make sure the Flexbus OU
power supply is switched off before connecting the cable to the outdoor unit.
Power can be switched off using the manager software.
