The length of the exposed (stripped) copper wires is important.
The ideal length is 3/16 inch (5 mm). Longer bare wires can short together.
Shorter wires are not as secure in the connectors and could be pulled out.

Connector Wire Preparation
• The MLC 104 IP Plus is powered from the PVS 405D associated power supply.
• Do not tin the power supply wires before installing them in the direct insertion
connector. Tinned wires are not as secure and could be pulled out.
