6.5.2 Connecting the SCK-C-MODBUS communication module

In the control cabinet, snap the device onto a 35 mm DIN rail in accordance with DIN EN 50022.

Install the power supply, RS-485 communication, and the SOLARCHECK measuring de-

vices as per the connection description in Section 6.1 on page 39 and the following connec-

tion diagram:

1. First, connect all of the desired measuring modules to the corresponding T inputs of the

device.

To do this, wire the data inputs (T1 … T8) to the respective data outputs of the measur-

ing modules (SCK BUS). Two cables are required for each data link to the measuring

modules. The cables may be swapped.

2. Next, connect the RS-485 connections.

To do this, wire data output (A) to the positive input of the RS-485 master and data out-

put (B) to the negative input of the RS-485 master. The internal shield of this cable can

be connected to the terminal block (GND2) so that the potential of the RS-485 network

line is also routed. Instead of the internal shield, a third wire can also be used, for ex-

ample, to route the potential in the RS-485 network. Also make sure that the external

shield of the data cable is additionally connected to ground at both ends so as to pre-

vent inductive couplings in the system from the power cables.

3. Wire the Modbus devices present in the RS-485 network with a maximum length of

1200 m. Follow the cabling recommendations in Section “Cabling” on page 44 and ter-

minate the start and end of the network following the established procedure for RS-485

networks.
