Selecting the correct cable entry system depends on the cable type, mounting cut-out, environmental conditions and application requirements.
Choose a split cable entry system when cables are already fitted with connectors:
- EWO 9000 Series
- EWO 9100 Series
Choose a membrane cable entry system for unterminated cables:
- EWO 9200 Series
- EWO 9210 Series
- EWO 9220 Series
- EWO 9230 Series
EWO systems are available for:
- Circular openings
- Square openings
- Compact rectangular openings
- Standard 10, 16 and 24-pole connector cut-outs
Choose the IP rating based on the installation environment.
- Protection Rating IP66: 9000, 9100, 9210 Series
- Protection Rating IP65: 9200 Series
- Protection Rating IP64: 9220, 9230 Series
The number of cables that can be installed depends on the size of the cable entry system and the diameter of the cables to be fed through. The configuration must be chosen according to the requirements of the application, ensuring that the cables are correctly housed and that the required degree of protection is maintained.
Depending on the application, verify compliance with:
- EN 62444
- UL File E535849
- UL94 V0
- UL / NEMA requirements
