ASSEMBLE PROCEDURE
Step 1
Put the 1st PEL-3211A on the bottom of the rack followed by fastening
the 4 screws for side bracket in the front but not tightening them
completely.
Step 2
Screw the L-shape brackets in the interior side of rack. An approx. 1mm
distance between the bottom of brackets and the top of PEL-3211A is
required.

Step 3
Put the 2nd PEL-3211A onto the L-shape brackets within the rack and,
again, fasten the 4 screws for side bracket in the front but not tighten
them fully followed by screwing another group of L-shape brackets
within the interior of rack.

Step 4
Repeat the previous steps in order to install the rest of PEL-3211As and
further install the bracket (GRA-414-3) of PEL-3111A on the upper side
followed by installing the PEL-3111A onto the top of the bracket.

PARALLEL CABLES INSTALLATION
Step 1
Install the parallel cables in accord with the following figure.
Note
The last cable connecting to the last unit cannot be clipped with core. When
only one PEL-3111A connects to a PEL-3211A (Booster) in parallel, the cable
in the Booster end cannot be clipped with core.

CONNECT TO AC POWER CORD
Step 1
Refer to the figure below; connect the AC power cords for all units to the
power sockets in the rear side individually followed by powering on the
power switch that is underneath the power socket (─ indicates power ON).
Step 2
Attentively check if the indicator in the front panel of all units lights up
with red color:
I. Master indicator lights up as the figure below:
II. Booster indicator lights up as the figure below (STBY indicator
lights up):

SYSTEM IN SERIAL SETTING
Step 1
Power on the power switch in the Master front panel and the indicator
lights up in green as figure below shown:
Step 2
The master will automatically detect the number of Boosters connected in
parallel. Please restart the system by turning off and on the power switch
of the electronic load.
Note
Select Booster number corresponding to the actual Booster number in parallel.
Step 3
Properly confirm if the indicator in the front panel of all PEL-3211A
(Booster) lights up with LINK in green, which means the software setting
connects to Booster appropriately. Refer to the figure below.

CURRENT SINK CURRENT
DIVISION CHECKUP
Description
The current sink power of PEL-3111A and PEL-3211A is 1KW:2KW;
therefore, the ratio of current sink will always be the exactly 1:2.
E.g., PEL-3332A (3KW); when current sink is set 30A, Master (PEL-3111A)
will sink current by 10A, whilst Booster (PEL-3211A) will sink current by
20A.
E.g., PEL-3955A (9KW); when current sink is set 90A, Master
(PEL-3111A) will sink current by 10A, whilst the rest of the 4 Booster
(PEL-3211A) will sink current by 20A individually.
Step 1
First dismantle all of the positive parallel copper sticks and parallel cables
in the rear output terminal of unit.
Step 2
Check the 1st Booster current:
I. Connect the parallel cable to the J2 connector in the rear of
PEL-3111A in one end and the J1 connector in the rear of
PEL-3211A in the other end.
II. Power on both PEL-3111A and the 1st PEL-3211A, while keep the
rest units power-off. Set the unit PEL-3111A as the parallel mode
via the following procedure:
III. Based on the connection method in the figure below, connect
current sink cable to the unit followed by setting current sink
value for unit. Measure the currents from both the current sink
cable of Master positive pole and the current sink cable of Booster
positive pole, via current probe, to validate the accuracy of
currents. The measured current value of Master is supposed to be
1/3 of the set value, whereas the measured current value of
Booster should be 2/3 of the set value.
