3.4.3. Connecting the Auxiliary Supply Cable (24 V)
Connect the auxiliary supply to the 24 VDC terminal block on the bottom of the Tuba.
Remember, you are working with DC power; so be sure to exercise caution.
Notes for 24 VDC auxiliary supply connections:
• Use a 24 AWG twisted pair shielded cable. For best results the shield should have
aluminum foil covered by copper braid.
• The 24 VDC auxiliary power supply must meet all safety standards and must be separated
from hazardous live voltages using reinforced or double insulation in accordance with
approved safety standards.
• For safety reasons, connect the return of the 24 VDC source to the closest ground.
• Connect the cable shield to the closest ground near the 24 VDC source.
• Before applying power, first verify the polarity of the connection.
