Power supply connections

1. Make sure that the instrument’s POWER switch on the rear panel is at the OFF position.

2. Connect the supplied power cord to the AC INLET on the instrument’s rear panel.

3. Connect the other end of the power cord to an AC outlet. Make sure your S90 ES meets the

voltage requirement for the country or region in which it is being used.

Make sure your S90 ES is rated for the AC voltage supplied in the area in which it is to be used (as listed on the rear panel).

Connecting the unit to the wrong AC supply can cause serious damage to the internal circuitry and may even pose a shock

hazard!

Use only the AC power cord supplied with the S90 ES. 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 S90 ES 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 S90 ES. 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.
