3.4.5 MASTER - SLAVE PARALLELING INTERCONNECTIONS (M5283) (cont.)
ROUTINE POWER-UP, PARALLELED SYSTEM
The following procedure is recommended to turn on paralleled systems after it has been
verified that the installation is correct.
1. Set the OUTPUT POWER switch of the Master Chassis (that which has the controller
installed) to the OFF position. The Output Power Switch of the Slave chassis is
disabled. Switch the INPUT POWER switch of the Master chassis to the ON
position. Switch the INPUT POWER switch of the Slave chassis to the ON position.
This sequence is recommended so that the power amplifiers of the system operate in
a controlled manner during power-up. The controller will light up and begin to
display output data. The value of the output parameters will be set as programmed
in the UPC.
2. Set the OUTPUT POWER switch of the Master chassis to the ON/AUTO position and
press the OUTPUT ENABLE button of the UPC to be ON.
CAUTION
DO NOT CONNECT ANY LOADS TO THE OUTPUT OF THE POWER SOURCE UNTIL THE
OUTPUT VOLTAGE AND FREQUENCY HAVE BEEN VERIFIED AS CORRECT.
APPLICATION OF IMPROPER VOLTAGE OR FREQUENCY CAN DAMAGE USER LOADS.
NOTE: Paralleled units must all be the same model. That is, only a
345-AMX may be paralleled with a 345-AMX, a 160-AMX may
only be paralleled with a 160-AMX. Connection with dissimilar
power sources will likely cause an output fault and may cause
damage to the equipment or the load.
It is the installer’s responsibility to meet all local and national
electrical codes when installing this equipment.
WARNING
LETHAL VOLTAGES ARE PRESENT AT THE OUTPUT TERMINALS OF THIS MACHINE!
