Input Power; Clearance And Location - Toshiba Strata DK40 Installation & Maintenance Manual

DK40 Installation

Input Power

The system requires an input power source of 220~240 VAC, 50/60 Hz, 13 amps. The AC
outlet is recommended to be dedicated and unswitched, with a solid third-wire earth.
"AC Power and Earthing Requirements" on Page 2-4 for more
This eliminates interference from branch circuit motor noise or the like, and to prevent
accidental power-off. To avoid accidental power turn-off, Toshiba recommends that you do
not use an ON/OFF wall switch on this dedicated AC circuit.
For the Strata DK40, a reserve power source (two customer-supplied 12-volt batteries) may
be connected to the system to serve as a power failure backup.
