4.3.6 Response to the connection of a 120 V AC or 230 V AC termi-

nal in the 24 V DC area

An AC terminal can be inserted in the 24 V DC area. The effects are described in Table 4-4.

A 24 V DC terminal cannot be inserted accidentally in an AC area as these terminals

are not mechanically compatible.

Effect/description

AC power terminal in the 24 V

DC area

No danger to people or machines.

Specified interface between a 24 V DC area and an AC area.

The AC power terminal consists of two function parts:

– The left-hand part interrupts the jumpering of U

S

, U

M

, GND, and FE

– The connections for the power supply and the jumper contacts for L, N, and PE are

on the right-hand part

Digital AC output terminal in

the 24 V DC area

No direct danger to people.

If the output is activated, the Triac output may be forced to trip and no longer switch off

because the supply voltage does not pass through zero.

NOTE: Possible malfunction

This is likely to be caused by a malfunction of the actuator connected to the rele-

vant output.

Digital AC input terminal in

the 24 V DC area

No danger to people or machines.

The input does not function due to missing ground.

Relay terminal in the 24 V

DC area

No direct danger to people.

The module has no diagonal routing, so there is no direct danger from the terminal,

even with a 230 V connector. This means that the shortest isolating distance is the dis-

tance from one connector to the next. This isolating distance is not permitted. There-

fore, insert a distance terminal (order designation IB IL DOR LV-SET-PAC) before and

after the relay terminal.

AC end terminal in the 24 V

DC area

No danger to people or machines.

The terminal offers neither diagonal routing nor connector connection.
