Power SupplyΒΆ

The supply voltage of 24 VDC is connected to a removable 5-pin terminal block. L+/M exist twice. It is therefore possible to feed e.g. external sensors (up to 8 A max. with 1.5 mm:sup:2 conductor) via these terminals.

Faulty wiring on power supply terminals

Attention

:strong:Risk of damaging the processor module and terminal \ base!

Exceeding the maximum voltage could lead to unrecoverable damage to the system.

The system could be destroyed.

Attention

:strong:Risk of malfunction!

To ensure reliability and proper functionality, the supply voltage must ramp-up from 0 V to 24 V within max. 2.5 s

Attention

:strong:Risk of damaging the terminal base and power supply!

Short circuits might damage the terminal base and power supply.

Make sure that the four clamps L+ and M (two of each) are not wrongly connected (e. g. +/- of power supply is connected to both L+/L+ or both M/M)

Attention

:strong:Risk of damaging the terminal base!

Terminal base can be damaged by connecting the power supply terminal block (L+/M) to COM1.

Make sure that the COM1 terminal block is always connected to the terminal base even if you do not use COM1 to prevent this.

Attention

:strong:Risk of damaging the terminal base!

Excessive current might damage the clamp and terminal base.

Make sure that the current flowing through the removable clamps never exceeds 8 A (with 1.5 mm:sup:2 conductor).
