2.4.2 Terminating Block Connectors
Block connectors, also known as Euroblock or Phoenix connectors, have terminals with
two connection points at each terminal. Each connection point accepts one solid wire with
a maximum wire size of 0.518 mm² (20 AWG).
Connectors are required for the room bus, passive bed light switching relays, and other
connections. Each connector has a screwless, spring-cage connection technique and each
terminal has two connection points. The Ascom Telligence System uses 4-, 6-, and 8-pole
block connectors.

Note: Block connectors are not supplied with modules but are available as
accessories and must be ordered separately.
To prepare the wires for a block connector:
1. Strip the jacket from the cables.
2. Pull the wires through the module’s housing leaving a length of 15cm (6.0in.) free.
3. Strip 0.64cm (0.25in.) of the insulation from the end of each wire to be connected.
To attach a wire to a block connector:
1. After stripping the wire to expose 6.5mm (0.25in.) of conductor, insert the wire in the
appropriate opening of the connection point by pressing the wire firmly into the
terminal, as shown below.
