PBZ
Parallel Operation
Connection
p. 30
To ensure stable operation, you must wire the load correctly. If the load is not wired correctly,
the PBZ may exhibit unstable operation such as oscillation. Use the shortest cables possible
to wire the load.
1
Turn the master and slave units off.
2
Remove the terminal covers from the master unit’s rear panel
PARALLEL terminal OUT and the slave unit’s rear panel PARALLEL
terminal IN.
Keep these terminal covers in a safe place. When you are not using the PBZs in
parallel operation, disconnect the parallel operation signal cable, and be sure to
attach the terminal covers.
3
Use the parallel operation signal cable to connect the master unit’s rear
panel PARALLEL terminal OUT and the slave unit’s rear panel
PARALLEL terminal IN.
4
Remove the OUTPUT terminal covers from the master and slave units.
The OUTPUT terminal cover screws will be reused later.
5
Attach the OUTPUT terminal short bar between the chassis and COM
terminals on both the master and slave units.
6
Attach the Insulation sheet between the OUTPUT terminals, and then
use the OUTPUT terminal connection bar to connect the OUT terminals.
Connect the COM terminals in the same manner.
Use the screws for the OUTPUT terminals.
7
Connect the load cables to the OUTPUT terminal connection bars.
p. 29
Use the screws for the load cables. The bar connected to the OUT terminals is “hot,”
and the bar connected to the COM terminals is common. Use load cables that have
sufficient current capacity.
8
Attach the OUTPUT terminal covers to the master and slave units.
9
For the PK01-PBZ, attach the parallel output terminal cover over the
OUTPUT terminal connection bars.
For the PK02-PBZ or PK03-PBZ, attach a cover to the back of the rack.
(You must provide the cover yourself.)

WARNING
To avoid electric shock, observe the following precautions.
• Turn the POWER switch off before you touch the OUTPUT terminals. Attach the
OUTPUT terminal cover after you finish wiring the load.
• The PK02-PBZ and PK03-PBZ do not include covers for the OUTPUT terminal
connection bars. Attach a cover to the back of the rack after you finish wiring the
load.
• The rear panel may become hot during operation. If you touch it, you may burn
yourself. Before you touch the rear panel, turn the POWER switch off, and allow a
sufficient amount of time for the rear panel to become cool.
• Be sure to connect the chassis terminals and the COM terminals with the short bars.
If you do not, the PBZs may not meet their specifications.
