Mechanical lift
Phillips (+) screwdrivers, number 2
M320 Installation Safety Guidelines on page 323
M320 Cabinet Size and Clearance Requirements on page 88
M320 Chassis Description on page 7
Because of the router's size and weight—up to 439 lb (199.6 kg) depending on the
configuration—we strongly recommend that you install the router using a mechanical
lift.
NOTE: To avoid harm to yourself or the router as you install and maintain it,
follow the guidelines for working with and near electrical equipment, as well
as the safety procedures for working with routers. However, providing an
exhaustive set of guidelines for working with electrical equipment is beyond
the scope of this documentation.
