Important information about voltage areas

4.3.5 Safety mechanisms to prevent incorrect connection of ter-

minals for different voltage areas

4.3.5.1 Protection against the insertion of 24 V DC terminals and power-level

terminals in the 120 V AC/230 V AC area

Extra-low voltage terminals and power-level terminals cannot be snaped-on within a low

voltage area because there is no keyway on the right-hand side of the low voltage termi-

nals (120 V AC/230 V AC).

WARNING: Dangerous contact voltage

The power terminals for the 24 V DC area can be inserted in a 120 V AC/230 V AC

area. The minimum isolating distance in this case is the distance between two ad-

jacent connectors. This isolating distance is not permitted. Therefore, only use end

terminals that are designed for terminating the 120 V AC/230 V AC area.

4.3.5.2 Protection against the connection of 24 V connectors to 120 V AC/230 V

AC terminals

The two terminal points for the low voltage I/O terminals are closed using filler plugs. The

connectors for extra-low voltage terminals therefore do not fit on the low voltage termi-

nals.

Exception 1: The extra-low voltage connectors can be plugged into 120 V AC/230 V AC

power terminals.

This connection error has no hazardous effect on the electrical components, but it can

lead to system malfunctions.

Only the appropriate connectors should therefore be plugged into the low voltage power

terminals.

Exception 2: The extra-low voltage connectors can be plugged into relay terminals. Be-

cause the relay outputs are floating, this connection error has no adverse effects.

4.3.5.3 Protection against the connection of live 120 V AC/230 V AC connectors

in the 24 V DC area

If the connectors for the I/O terminals are wired according to the installation instructions,

they are disconnected from the power supply when removed.

The following connectors may be live in the low voltage area:

– Connectors of the power terminals for the 120 V AC and 230 V AC areas

– Connectors for relay terminals

These connectors are closed using filler plugs in some places and therefore do not fit on

the terminals of the 24 V area.
