Cellwatch Frontier System Installation & User Manual
Section I – Installation Guide-20
DCM6-R
The DCM6-R is designed to measure string ripple voltage on 2 volts cells up to a maximum string voltage
of 300 volts. The white wire should be connected to the negative side of the Frontier cabinet fuse and
the brown wire to the positive side. The DCM6-R is usually configured to be the last DCM on the fiber
loop. You should null all the DCM6-R channels so that Frontier does not try to read voltage or Ohmic
value.
