To peel the fi lm from the lead cable, use a dedicated tool that will not damage the
conductor cable.
When installing a screw on the terminal block, do not cut the cable by overtightening
the screw. On the other hand, an undertightened screw can cause faulty contact, which
will lead to a communication failure.
