M SERIES DAC

INSTALLATION

____________________________________________________________________________

CAUTION: High-voltage surges and spikes can damage this equipment.

To protect from such power surges and spikes, this unit must have a good

earth ground. There is an earth ground connection next to the power input.

CAUTION: Before removing or replacing any cables or power cords, turn

off main power switch located on the M Series Unit. Communication to the

unit will be disrupted while power is off.

CAUTION: Do not exceed the AC current rating for the selected model.

CAUTION: Although the power switch is turned OFF, the unit is not

totally isolated from the power supply. In order to be absolutely removed

from the power supply, the power cord must be unplugged from the unit.

CAUTION: For PERMANENTLY CONNECTED EQUIPMENT, a readily

accessible disconnect device shall be incorporated in the fixed wiring. For

PLUGGABLE EQUIPMENT, the socket-outlet shall be installed near the

equipment and easily accessible.

CIRCUIT BREAKER (In which units is this installed?)

In the case of power overload, the circuit breaker automatically trips. Determine the

cause of the tripped circuit breaker, correct the problem then reset the circuit breaker

by depressing the circuit breaker switch.
