When connecting a device with heating to the CDM420-0001 connection module, the
supply voltage supply lines for the heating are protected by the fuse on the additional
connection circuit board.
The maximum permissible wire cross section on the screw terminals in the
CDM420-0001 is 2.5 mm
2
.
If the device is not operated with UL-compliance, the maximum permissible current to
the screw terminals is 20 A in accordance with the specification of the terminals.
This enable parallel switching of several CDM420-0001 modules with connection devi‐
ces with heating.
Using connection module CDB620-001
When connecting a device with heating to a CDB620-001 connection module, the sup‐
ply lines of the supply voltage to the CDB620-001 are to be protected at the customer
site by a 3 A fuse in the control cabinet.
A separate fuse is to be used for every connection module and device. The additional
terminal (DC 24 V) and terminal 2 (GND) are provided for connecting the incoming sup‐
ply voltage in the CDB620-001. The operating voltage reaches terminal 3 (U
IN
) via the
heating switch.
