For the bipolar (dual-quadrant) mode with shunt method of current
sensing, the magnet power supply system consists of the Model 430
Programmer, one or more unipolar 08150PS power supplies (each
typically configured for +10 VDC/120 A output), and one or more Model
601 Energy Absorber with associated interconnection cabling and
buswork.
Referring to the diagram on page 22, ensure the cabling is connected in
the following manner:
NOTE
The use of locking hardware is recommended for all high-current
connections.
CAUTION
Do not overtighten the hardware on the interconnection
terminals (refer to specifications table on page 8 for torque
limits). Overtightening can result in damage to the
terminals.
WARNING
Ensure the protective diode is installed across the output
terminals of the power supply with the anode at the
negative (–) terminal and the cathode at the positive (+)
terminal. Removal or omission of this protective diode may
cause serious injury to personnel and damage to the power
supply under loss of AC power conditions.
a. Connect the protective diode between the output terminals of the
power supply: anode to the negative (–) terminal and the cathode to
the positive (+) terminal.
b. Connect the positive (+) output terminal
ì
of the power supply to
the Model 601 Energy Absorber positive (+) terminal
î
.
c. Connect the negative (

ï
of the Model 601 Energy
Absorber to the positive (+) magnet current lead

.
d. Connect the negative (

ó
to the positive (+)
resistive shunt terminal

on the back of the Model 430
Programmer.
e. Connect the negative (

of the Model
430 Programmer to the negative (–) output terminal of the power
supply

from terminal block position S- to M- and
from S+ to M+ on the power supply unit.
