ATTENTION:
ALWAYS CONFIGURE THE DIP SWITCH SETTINGS IN ACCORDANCE WITH THIS MANUAL BEFORE CONNECTING ANY POWER CABLES TO
THE BATTERY TERMINALS B+ AND B-.
WHEN CHANGES HAVE BEEN MADE TO THE DIP SWITCH SETTINGS, THE BATTERIES MUST ALWAYS BE RESTARTED FOR THE CHANGES TO
TAKE EFFECT.
POWER CABLE CONNECTIONS MUST BE MADE IN STRICT ACCORDANCE WITH THE INSTRUCTIONS IN THIS MANUAL. INCORRECT POWER
CONNECTIONS CAN DAMAGE THE BATTERY MODULE AND CAUSE INJURIES.
WHEN THE INVERTER HAS A CANBUS COMMUNICATION PORT, SWITCH #7 OF THE MASTER BATTERY MUST ALWAYS BE SET TO
“ON.”
ATTENTION:
All drawings are for reference only. Always refer to
the physical product as the standard. If the manual does
not match the physical product, stop all actions, remove any connections, and store the batteries in a safe place.
Call your WeCo technical service representative for assistance.
2.5 Low Voltage Parallel Set Up Overview
5K3-XP can be connected in parallel up to 15 modules, this process requires a full knowledge of the product.
DIP Configuration for LOW Voltage Parallel
CAUTION
:
For a single cluster installation, it is necessary that the DIP switches of
the batteries
are set as below.
All switches are set to “OFF”
with the only exception of the last module that must have
the DIP 6 Enabled to activating the Terminator Resistance
( See below)
After setting the DIP Switch, the Battery Module must be restarted for the DIP switch changes to take effect.
•
Once the DIP Switches of the single cluster have been set, it will be possible to perform the connection of the earth terminal
between the modules and the general earth rod, and subsequently it will be possible to connect the RS485 B Port of the Master
battery with the RS 485A Port of the SUB-1 battery using the RJ45 cable supplied.
•
Continue to connect the RS485 ports in sequence up to the last module.
•
Set the Power Switches on all batteries to the ON (1) position.
•
Press the RUN BUTTON of the MASTER ONLY to initiate the cluster automatic start up. There is NO NEED to press any of the Sub
Module Run Buttons as they will be configured automatically when the Master Run Button is pressed.
•
Wait until the Run Buttons on all modules are a STEADY GREEN.
Finally, it will be possible to proceed with the power connections using the BUS BAR (accessory) if you are installing in stackable mode or,
if the installation is wall or floor mounted, you can use battery cables properly sized according to the distance between the modules.
The connection between the INVERTER and the MASTER / LAST MODULE must be performed using cables.
(If you need to connect more than 5 modules in parallel it is necessary to create more towers composed of 5 modules, and connect them
in parallel with each other via cables).
