can be used. The female con-
nector strip is secured in position by means of a screw-type locking.
The female connector strip of the type Phoenix COMBICON MSTB 2.5/3-STF is

Hazardous voltages can exist inside electrical installations that can pose a danger
to humans. Coming in contact with live parts may result in electric shock!
Please note with respect to pin assignment:
If shielded connecting cables are used for the supply voltage, the shield should be
connected to the ground screw.
Any protective conductors in the cable must be connected with pin 1.
Separate ground screw for protective grounding
A separate ground conductor must be provided for the ground screw in each case.
The minimum cross-section of the ground conductor must be 1.5 mm
