Appendix D: Power Guidelines, Requirements, and Specifications for the M40e Router
CAUTION: Before router installation begins, a licensed electrician must attach
a cable lug to the grounding and power cables that you supply. A cable with
an incorrectly attached lug can damage the router.
To ground AC-powered and DC-powered routers, connect a grounding cable to earth
ground and then attach it to the chassis grounding points. The grounding points are
spaced at 0.625-in. (15.86-mm) centers. The accessory box shipped with the router
includes the cable lug that attaches to the grounding cable (see Figure 128 on page 277)
and the UNC 1/4–20 screws (American) used to secure the grounding cable to the
grounding points. (The cable lug shown in Figure 128 on page 277 is also used for the DC
power cables.) The grounding cable must be able to handle up to 68 A.

The grounding cable must be 6-AWG (13.3 mm
local code.
NOTE: Additional grounding is provided to an AC-powered router when you
plug its power supplies into grounded AC power receptacles.

Detachable AC power cords, each 2.5 m (approximately 8 ft) long, are supplied with the
router. The C13 appliance coupler at the female end of the cord inserts into the AC
appliance inlet coupler, type C19 as described by International Electrotechnical
Commission (IEC) standard 60320. The plug at the male end of the power cord fits into
the power source receptacle that is standard for your geographical location.
NOTE: The AC power source must supply 220 VAC power (nominal range
200–240 VAC), not 110 VAC power (nominal range 100–120 VAC).
