CONNECTING TO THE FIRSTLINE PL BATTERY CABINET
To be performed by authorized service personnel:
1.
Inspect battery trays for signs of damage. Verify that all terminal connections are
sound. The red and black “powerpole” connectors will be connected, but the
blue and white connectors on the wires joining the trays in the string should not
be connected.
2.
If possible, after connecting the loose “powerpole” connections (blue to blue,
white to white), use a voltmeter to verify that the battery string is above 408 VDC
at the TB3 connector. If the voltage is low or the voltage varies significantly from
string to string, please consult Staco service.
