Installing the CLH21A shield plate extension for sizes 0S and 0L
The CLH21A shield plate extension (mounting rail on a standard shield plate) is used to mount additional terminal blocks or modules on the inverter shield plate. The brake rectifier from SEW-EURODRIVE or a multi-level terminal block, for example, can be attached to the CLH21A shield plate extension. This offers the following benefits:
- No additional hat rail required for terminal blocks or modules.
- No additional control cabinet space required, as direct stacking of inverters is still possible.
- Easy wiring of terminal blocks or modules thanks to optimal cable routing.
