TRICONEX 3706A Thermocouple output card

If you are intending to use a SV4500S/SV8500S with an external EMC filter, it is recommended the filter is mounted next to the drive as shown in Figure 3-10. Both the drive and filter must have good electrical contact with the cabinet metalwork, which can be achieved for the drive by making use of its un-painted mounting surface areas located on the underside of the top and bottom metalwork fixings. This will require any surface coating to be removed on the panel to which the drive is being mounted, but only over the area making contact with the drive. In a similar fashion, the surface coating of the panel beneath the EMC filter’s mounting metalwork will also need to be removed to ensure good electrical contact between filter and mounting panel.

Wiring between the EMC filter

drive needs to be made with 2.5mm2 (14AWG) wire kept as short as possible. 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 and the lockwasher on the EMC filter.

Surge Protection

 Using one of the EMC mains filters specified will provide protection against mains surges of 2kV (1.2/50µs rise/fall time). If the drive and filter combination are used in an environment where surge levels greater than 2kV may be expected, or where an EMC filter is not used, additional surge supression systems will need to be provided. Contact Parker or your Automation Technology Centret if your application needs extra surge protection.
