(1)

AC Adapter

Important

・Use the provided AC adapter when using AC power supply.

・Use the provided DC cable when using DC power supply.

・Do not use batteries when connecting the unit to a network. (Batteries are rapidly

consumed.)

Note

・A power switch is not provided on the unit. The unit starts operation immediately when the

power is supplied.

・The external power supply is normally used as the primary power source when both

external power supply and batteries are provided in the configuration. Batteries are used

when the external power supply fails due to power outage or other reason. The unit

automatically switches to the battery supply in such an event provided the batteries are

mounted in the unit.

(1) Insert the AC adapter or DC cable plug into the power

supply terminal on the unit.

(2) Connect the AC plug of the AC adapter to an outlet (100 VAC

to 240 VAC) when using AC power supply. To use DC power

supply, connect the white-lined wire of the DC cable to the

power input (24 VDC±10%) and the non-lined wire to 0V.
