Connections
Correct connection of the units to the power supply will decrease the chances of units malfunctioning due to cabling
problems. Please follow these basic rules.
a) Use the correct type & gauge of cable & connectors.
b) Keep cable runs as short as possible to reduce line loss.
c) Always use a return cable for each run. This will ensure balanced DC power to all units, that the line is correctly
terminated, & all units receive power if one link of the chain is faulty.
2.2 Operating the unit
All the unit functions are accessed using the LED display & the three push-button switches on the rear panel.
