MLC Plus 50/100/200 Series • Hardware Features and Installation 15
Installation Step 4: Cable All Devices
NOTE: Most examples on the following pages show the MLCPlus100. However,
connector wiring and port functions are identical for all models.
1. If the MLC Plus is not mounted to a grounded metal junction box or a grounded metal
equipment rack, Extron recommends connecting the unit to an earth ground to protect
the unit from electrostatic discharge.
To ground the unit:
a. Securely terminate a grounding cable with a ring terminal.
b. Remove the grounding screw in the lower left corner of the rear panel, insert the
grounding cable, replace and securely fasten the screw (hand-tighten only). Do not
over-tighten the screw. Maximum torque is 2 inch-pounds (0.2 Newton-meter).
