Bad wiring on power supply terminals

Attention

:strong:Attention:

The product should be installed by trained people who have the knowledge of wiring electronic devices. In case of bad wiring, although the modules are protected against various errors (reverse polarity, short circuit, etc.), some problems could always happen:

• On the CPU Terminal Base, the terminals L+ and M are doubled. If the power supply is badly connected, a short circuit could happen and lead to a destruction of the power supply or its fuse. If no suitable fuse exists, the Terminal Base itself could be destroyed.
• The CPUs (Terminal Bases) and all electronic modules (and Terminal Units) are protected against reverse polarity.
• All necessary measures should be carried out to avoid damages to modules and wiring. Notice the wiring plans and connection examples.
