Option 913 synthesizers are supplied with rack flanges and the

necessary hardware to install them on the synthesizer without

removing the instrument handles. The following table itemizes the

parts in this kit.

When installing the instrument in a

cabinet, the convection into and out of the instrument must not be
restricted. The ambient temperature (outside the cabinet) must be
less than the maximum operating temperature of the instrument
by 4 

 for every 100 watts dissipated in the cabinet. If the total

power dissipated in the cabinet is greater than 800 watts, then forced
convection must be used.
