TRICONEX 3623 Thermocouple input card

AC power wiring needs to be made with 2.5mm2 (14AWG) wire. The earth (ground) connection should be made using colour coded 2.5mm2 (14AWG) wire using crimped ring terminal contacts. The cable used should be rated for at least 1500V AC. All ring terminal contacts need to be assembled as shown in Figure 3-11, with the split ring washer used to tension the electrical contact on the drive’s protective earth connection.

Very high voltages are present on the dump connection terminals. Ensure all terminals and wires are protected from accidental contact.

SV4500S/SV8500S Dump Connections 

In normal operation an insulated wire link is made between RD and TD to use the internal 33 dump resistor. When an external dump resistor is used the link is removed and the external dump resistor is connected between HV and TD. The resistance value of the external dump resistor must be 22 absolute minimum and of sufficient power rating to dump the regenerated energy during motor deceleration. If you need help deciding the wattage of resistor required, please consult your supplier.

EMC Filter for SV2500S 

The SV2500S can use a CORCOM 12FC10 EMC filter, as shown in Figure 3-9. The installation of such a filter needs to follow all the guide lines given for the SV4500S and SV8500S, given in the following sub-section. Supply wires and earth (ground) need to be made using 2.5mm2 (14AWG).Alternative filter types may be used provided the given specification can be met or improved upon. When powered from a 3-phase 230V supply, a CORCOM 12FCD10 EMC filter should be used. This filter has a similar characteristic to the 25FCD10 used with the SV8500S and has the dimensions given in Figure 3-12.
