5. Auxiliary Connector
This connector is an Andersen Power Products Power Pak 6 Position connector.
The auxiliary connector has internal form-C relay connections and the connection
for an external balancing resistor; one position is empty (red).
The form C normally closed contact is connected to the black and green
positions on the auxiliary connector. The normally open contact is connected
between the yellow and black positions on the auxiliary connector. Both contacts
actuate to the normal position on power up if the MKM is functioning properly.
The relay is rated at 1A continuous and 12V maximum.
The external balancing resistor is recommended to be a 300W 25Ohm resistor
for rapid balancing. This resistor is required to rapidly balance MKMs when in
series connect mode. The resistor connections are the Blue colored contacts in
the auxiliary connector.
6. Breaker
The breaker is a secondary level of protection against output faults. It also
controls the power output of the MKM and allows the MKM to go into sleep mode
when in the off position, saving power during storage or transport.
7. Case Interlocks
The MKM Case has interlocking features for stacking and securing MKM
batteries both horizontally and vertically. It is recommended stacking be limited
to 4 MKM batteries high in all applications. The MKMs can be used in any
attitude, orientation does not matter.
INTERLOCK
FEATURES
Do not stack more than four (4) high
