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

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.
