supplied from a fixed installation).
1
Turn off ( ) the POWER switch on the front panel.
2
Check that the AC power line meets the nominal input rating of the product.
The product can receive a nominal power supply voltage in the range of 100 Vac to 120 Vac or
200 Vac to 240 Vac. The supported frequencies are 50 Hz and 60 Hz. (Frequency range: 47 Hz to
63 H
z)
3
Connect the power cord to the AC INPUT inlet on the rear panel.
4
Connect the power cord plug to an outlet with a ground terminal.
This completes the connections.
