Do not pull on the leads or damage insulation when connecting cables or handling wires.

Strain relief is planned for the power cables.

Test all parts on receipt and ensure that neither the lead nor its insulation is damaged in handling and/or

storage.

WARNING

Testing cable insulation

Improperly laid or damaged cables and incorrectly attached cable shields can heat up in places and cause fires or short-

circuits wherever they make contact.

• Ensure that cable shields are intact and replace all damaged parts.

• Ensure that no short-circuit can occur on the power cables due to insulation damage resulting from incorrect

installation.
