that phase, neutral and earth can be corrected to the relevant lugs as shown.

Step 3:

Fit load earth wires into the earth lugs as shown below and torque to the

recommended value from Table 1.

Insert the wire under the pressure plate and tighten it onto the wire with the

screw. Do not clamp the wire directly under the screw.

Step 4:

Fit load neutral wires into the neutral lugs in the same manner and torque to the

recommended value.

Step 5:

Fit load phase wires into the phase lugs in the same manner and torque to the

recommended value.

Step 6:

Tighten all load connections to the torque specified in the table below.

Table 1: Lug torque values

W A R N I N G :

If any wire splices are required (none are recommended), they must be

made with a crimp-style butt-splice. Terminal block is NOT acceptable.

C A U T I O N :

To prevent interference with cooling airflow, do not run load wires from one rack

through a different rack. See
