CAUTION

The conductors must be listed for PV applications and the site environment and

have the correct color coding to avoid material damage and bodily harm.

• The insulation color-coding of electrical conductors must be understood in order to

ensure safe and efficient installation, maintenance and repairs. Ensure compliance with

the relevant local and national regulations.

• Secure conductors so that they are kept away from objects that can damage the

insulation (e.g. sharp edges).
