Installing the base module
Prerequisite:
}
The head module must be installed.
}
If the head module does not have an integrated power supply, a supply voltage module
must be installed to the right of the head module.
Please note:
}
For mechanical reasons it is not possible to mix base modules with screw terminals and
base modules with cage clamp terminals.
}
All contacts should be protected from contamination.
}
The mechanics of the base modules are designed for 50 plug in/out cycles.
Procedure:
}
We recommend that you wire up the base modules before inserting the electronic mod-
ules.
}
Slot the groove on the base module on to the mounting rail from below [1].
}
Push the base module back [2] until you hear it lock into position.
}
On the mounting rail, slide the base module to the left until you hear the two lateral
mounting hooks on the adjacent module lock into position [3].
