Preliminary Guidelines
4.4 Conduits
The installation of Islander Prime requires preparing the cable layout in the homebase station
in advance. This procedure consists of installing conduits within the island, inserting the
proper cables, and setting the power equipment and sensors.
This section provides the procedures for infrastructure groundwork. These procedures are
presented in the order in which they should be performed:
• Wire conduits installation
• Cable routing within the conduits
• Power equipment setup
• Forecourt equipment wiring
4.4.1 Requirements
The installation of Islander Prime in the island requires digging and setting several conduits in
the station ground. The conduits are required for the routing and protection of the different
types of cables used in a homebase station with Islander Prime.
In sites where the infrastructure is already set up, you can use the existing conduits only if they
meet the requirements defined below.
Conduits must comply with the following requirements:
• All conduits must be made and installed according to local regulations.
• High-voltage AC and low-voltage DC must NOT be combined in a common conduit,
• RS-485 or LAN communication must not exceed 330 feet (100 m). Cables must be
• RS-232 communication must not exceed 50 feet (15 m). RS-232 communication shielded
• Antenna wires must not exceed 330 feet (100 m) in case the VIU is in use, and 50 feet
• All conduits must be inserted in the Islander Prime pedestal through the holes and
