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-3211 is required.
Put the 2nd PEL-3211 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.

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

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

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).
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):

Power on the power switch in the Master front panel and the indicator
lights up in green as figure below shown:
Press
Main
> Configure[F5] > Next Manu[F4] in the front panel
followed by selecting “4” for Booster number within Configure page,
which indicates 4 Booster units in parallel. See the steps figures below:
Select Booster number corresponding to the actual Booster number in parallel.

Properly confirm if the indicator in the front panel of all PEL-3211
(Booster) lights up with LINK in green, which means the software setting
connects to Booster appropriately. Refer to the figure below.

The current sink power of PEL-3111 and PEL-3211 is 1KW:2KW;
therefore, the ratio of current sink will always be the exactly 1:2.
E.g., PEL-3332 (3KW); when current sink is set 30A, Master (PEL-3111) will
sink current by 10A, whilst Booster (PEL-3211) will sink current by 20A.
E.g., PEL-3955 (9KW); when current sink is set 90A, Master (PEL-3111)
will sink current by 10A, whilst the rest of the 4 Booster (PEL-3211) will
sink current by 20A individually.
First dismantle all of the positive parallel copper sticks and parallel cables
in the rear output terminal of unit.
Check the 1st Booster current:
I. Connect the parallel cable to the J2 connector in the rear of
PEL-3111 in one end and the J1 connector in the rear of PEL-3211
in the other end.
II. Power on both PEL-3111 and the 1st PEL-3211, while keep the
rest units power-off. Set the unit PEL-3111 as the parallel mode
via the following procedure:
III. Select from the main interface
a. Configure > Next Menu > Parallel > Operation; select: Master
b. Configure > Next Menu > Parallel > Parallel; select: OFF
c. Configure > Next Menu > Parallel > Booster; select: 1

IV. 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.

The 2nd Booster current checkup:
I. Connect the parallel cable to the J2 connector in the rear of
PEL-3111 in one end and the J1 connector in the rear of PEL-3211
in the other end.
II. Power on both PEL-3111 and the 2nd PEL-3211, while keep the
rest units power-off. Set the unit PEL-3111 as the parallel mode.
The setting procedure is identical to the setting of the 1st
PEL-3211 validation.
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.
Follow the previous steps to validate the 3rd and the 4th Booster
respectively.
The assembly procedure and system setting are completely finished.
