3. Crimp the correct AWG power supply wire into the power lugs. For 2400W power supplies: #4 AWG power supply wire. For
3000W power supplies: #2 AWG power supply wire. Refer to the following gure.
CAUTION
For an ExtremeRouting MLX-32 AC system, use a ground wire of at least 2 American Wire Gauge (AWG). The
ground wire should have an agency-approved crimped connector (provided with the chassis) attached to one end,
with the other end attached to building ground. The connector must be crimped with the proper tool, allowing it to
be connected to both ground screws on the enclosure.
CAUTION
For an ExtremeRouting MLX-32 DC system, use a grounding wire of at least 2 American Wire Gauge (AWG). The
2 AWG wire should be attached to an agency-approved crimp connector crimped with the proper tool. The crimp
connector should allow for securement to both ground screws on the enclosure. Grounding position is located on
the side of the chassis adjacent ground symbol.
NOTE
To ensure adequate bonding when attaching the ground lug, a minimum of 20 PSI of torque is required to be applied
to the mounting hardware used to attach the ground lug.
