Attaching the cable clamp.
Be sure to properly ground the device to prevent possible electrical shock.
First plug the female-connector end of the AC cord into the [AC IN] socket on the rear panel of the
DME64N/24N, then plug the male plug into an appropriate AC mains outlet. Make sure the AC power to be
used complies with the conditions marked on the top cover of the device.
Use only the AC power cord supplied with the DME64N/24N. If the supplied cord is lost or damaged and needs to
be replaced, contact your Yamaha dealer. The use of an inappropriate replacement can pose a fire and shock hazard!
The type of AC power cord provided with the DME64N/24N may be different depending on the country in which
it is purchased (a third prong may be provided for grounding purposes). Improper connection of the grounding
conductor can create the risk of electrical shock. Do NOT modify the plug provided with the DME64N/24N. If the
plug will not fit the outlet, have a proper outlet installed by a qualified electrician. Do not use a plug adapter which
defeats the grounding conductor.
Setup
Security Cover Mounting
Security cover mounting screw holes (M3 size) are provided on the front panel of the unit. The spacings are
423mm width and 96mm (DME64N) / 52mm (DME24N) height. See “Dimensions” on page 67 for
details. A security cover made by the customer or contractor can be attached to the front panel via these
mounting holes to prevent accidental operation. Yamaha cannot supply a security cover.
When mounting a cover make sure that the screws used do not go deeper than 15 millimeters into the front
panel. Also, to ensure that the cover does not come in contact with the panel controls, leave a space of about
20 millimeters between the front panel and the cover.
