At a Glance

This is an overview of the sensor and pre-actuator connections on TELEFAST 2 bases.

NOTE: The bases are manufactured with a general-purpose, quick-blow fuse rated 6.3 A. To guarantee optimum protection, this fuse should be rated according to the application (connection to input or output functions) and the maximum current allowable in the base.

Type and rating of fuse to be fitted to the base:

  • input functions: 0.5 A quick-blow

  • output functions:

    • 2 A quick-blow on the ABE-7H16R•• base

    • 6.3 A quick-blow on the ABE-7H08R•• base

Connections for input and output functions.

Connecting the common for sensors:

  • onto terminals 1 or 2: sensors to the ‘+’ of the supply (positive logic inputs)

Connecting the common for pre-actuators:

  • onto terminals 3 or 4: pre-actuators to the ‘-’ of the supply (positive logic outputs)
