Mechanical installation
The SS202 can be used in conjunction with the CB or MSS series cabinets.
They provide a flexible and modular design. It's storage capabilities depend on
the number of SS202 modules installed into the cabinet, for example a limit of 3
modules for the CB-12 cabinet.

Electrical installation
Step 1. Before connecting anything be sure that battery is off and the ON/OFF switch (fig2
pos 3) is in the OFF position.

Connecting Inverters/chargers/UPS to the battery unit while it is ON can cause big sparks
due to capacitors inside the connected device. This could cause serious injuries.
Use the appropriately sized cable for connected devices.
Based on the rated current of the battery and inverter as well as cable length.
Figure 3 connection Busbar
Step 2. Connect the negative cable to the negative battery busbar and the positive cable to
the positive battery busbar as shown is figure 3.
All used connection points should be a suitably tightened, ensuring good electrical
connection between the lug and busbar. A bad connection could cause serious damage to
the battery, inverter and connected electrical components.

Commissioning
Step 1. Ensure all DC cables are tight according to specifications.
Step 2. If the battery operates in parallel with other Energy sources, make sure that the
difference between battery voltage and DC bus is not more than 2.5V. If greater than 2.5V
please Charge or Discharge other source accordingly until voltage difference is in safe
ranges under 2.5V, to avoid high equalization currents.
Caution! A bad connection with voltage drops can cause very high
equalization current which can burn the fuses of the battery!
Caution! Measure the voltage of the battery before connecting the dc
Cables.
Step 3. Turn BMS board ON/OFF switch to the ON position (figure 2 pos 3).
Step 4. Connect Multipurpose button if not connected to the BMS board connector see
(figure 2 pos 5).
Step 5. Hold Multipurpose button until light comes on.
Note: If commissioning two or more batteries.
Once the system is switched on and load is added, measure current flow on
each battery. Ensure that the load is distributed across each battery equally.
Warning! If the battery does not switch the Main contactor ON in 7
seconds, please check BMS board indication LED for faults. See section BMS
Error and Warnings on page 13 of this manual.

Button function
The new Solar MD Multipurpose button has an extended functionality in combination with the BMS-EM v10.01.
The Multipurpose Button can be used to directly execute 6 predefined functions and a shutdown instruction. In
combination with the 6 Indication LEDs on BMS-EM v10.01, the user can choose between each function by
holding the button until the LEDs count match the number of the function. By releasing the button while moving
through the functions, LEDs will start blinking and wait for the user to press the button again within 3 seconds.
The predefined functions are:
1. Reserved
2. Change indication LED function between: Show Capacity, Show Current, and
Off
3. Reserved
4. Wake up if Sleep mode is active.
5. Activate Override Off state for 60sec
6. Activate Override On state for 60sec
If the button is held continuously after function 6, shutdown mode is activated and the battery will send a signal
to switch off in 4sec.
Further holding the button causes the BMS to delay complete shutdown for a maximum of 3 minutes. This
operation is used when the technician wants to continue read or write parameters after shutdown.
