Using a multimeter, verify that 48Vdc is present at the connection
leading from the battery pack, and the polarity is correct. Connect the
battery pack to the Battery connection on the front of the unit. Note the
shape of the Battery connectors which prevent incorrect hookup. Verify
that the red alarm LED goes out within 10 seconds.
