Junction Box IF-8900

The junction box can be mounted on a desktop or bulkhead, and is required to connect
the remote station, wing handset, etc. Put the unit within 5 m of the transceiver unit,
because that is the length of the cable connected between the units.
For the bulkhead mount, it is necessary to cover holes in the bottom of the unit to
comply with the Ingress Protection Rating IPx2. Waterproof seals (Type: OP05-133,
Code no.: 001-174-890) are optionally available for this purpose. Set them to the open
holes on the underside of the junction box as shown below, BEFORE installing the
junction box.
