2.1 LINE VOLTAGE
The Beta D-50 can operate on either 115 or 230 Volts AC. The desired line voltage can
be selected on the rear of the unit.
CAUTION: Ensure that the unit is set for the appropriate line voltage before operation.
A. On the back of the unit locate the AC voltage select dial.
B. Set dial for appropriately marked AC voltage (115 or 230 volts) using a screwdriver.
C. For 230 VAC operation, the 115 VAC plug must be replaced with one for 230 VAC in
required configuration.
NOTE: If the plug has to be changed make sure to connect the green AC line wire to
ground.
Connect the unit to a wall outlet with at least a 10 ampere capacity. Sharing of the line
with other equipment may result in erratic operation if other equipment draws high pulse
or surge currents.
NOTE: The Beta D-50 will maintain its operational integrity with line fluctuation less than
± 10%.
2.2 TERMINALS
Two important points about the DC battery cable and connector are:
A. If the aircraft battery quick disconnect connector is removed, the
ring terminals can be used to connect to a post terminal battery.
WARNING : Correct polarity must be observed.
B. If the cable is extended or repaired during maintenance, the
sensing leads which run with the heavy DC cable must be
connected to the new terminal (see section 5.5).
