CABLING REQUIREMENTS
Before mounting the operator ensure your cabling and conduiting are in place to prevent any inconvenience at a later stage. Allow for
spare cabling in case of faulty cable & breakages (especially important when using low specification cable). If installing an intercom,
remember to allow for sufficient cable cores for all the uses on the system as per manufacturers cabling requirements.
