Tools and Parts Required for Connecting an MX2000 Router to Power
To provide power to the router, you need the following tools and parts:
•
Phillips (+) screwdrivers, numbers 1 and 2
•
2.5 mm flat-blade (–) screwdriver
•
7/16-in. (11 mm) hexagonal-head external drive socket wrench, or nut driver, with a torque range
between 23 lb-in. (2.6 Nm) and 25 lb-in. (2.8 Nm) tightening torque, for tightening nuts to terminal studs
on each power distribution module (PDM).
•
The terminal block connections on the AC delta and wye PDM use a 1/4-in. slotted screwdriver for the
slotted screws. Use a 5/32-in. (4 mm) Allen wrench for the 5/16-in. hex screws.
•
Wire cutters
•
Electrostatic discharge (ESD) grounding wrist strap
CAUTION: The maximum torque rating of the terminal studs on the DC PDM is 25
lb-in. (33.89 Nm). The terminal studs may be damaged if excessive torque is applied.
Use only a torque-controlled driver or socket wrench to tighten nuts on the DC PDM
terminal studs. Use an appropriately sized driver or socket wrench. Ensure that the
driver is undamaged and properly calibrated and that you have been trained in its use.
You may wish to use a driver that is designed to prevent overtorque when the preset
torque level is achieved.
