To ground and 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), for tightening nuts to terminal studs on each power

is 36 lb-in. (4.0 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 power
supply terminal studs. Use an appropriately-sized driver or socket wrench, with a
maximum torque capacity of 50 lb-in. or less. 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.
