correct rating is inserted into the cap and then the cap is screwed back onto the fuse holder base on the
back of the Frontier.
Warning: Remove power from the Frontier unit before
replacing fuse! Use rated fuse only!
Fiber Optics
The Frontier device connects via fiber optics to Data Collection Modules (DCM) that read cell voltages,
ohmic values, AC ripple voltage, and cell temperature (DCM 5T only). Frontier can communicate with up
to 64 DCMs, which allows it to monitor up to 256 channels.
All fiber optic connections connect from blue to black. The blue fiber optic connector is the transmit
port. The black fiber optic connector is the receive port.
Blue = Transmit
Black = Receive
Fiber optic communications are continuous unless a break in the fiber loop is detected. If a break is
detected, Frontier will generate a battery alarm and a DCM Failure error will appear in the user
interface. The Battery Alarm relay will trip if it is configured to do so. Frontier will attempt to reestablish
communications every hour for 48 hours. After 48 hours have passed, communications will not be
reestablished until all hardware issues are resolved and the user manually resumes scanning in
Diagnostics. This is done so that the DCM units can enter a low current draw state (i.e. Sleep mode) in
order to protect the batteries from continual current draw.
Connection Strain Relief
Strain relief should be used to ensure connections do not come loose during normal scheduled
maintenance. It is recommended to use a P connector or alternate form of strain relief to reduce the
stress on the wires connected to Frontier. Fiber optic cables do not require strain relief.
As an extra precaution, ensure a drip point is provided in the wires to prevent water or other liquids
from traveling down a wire and into the Frontier device.
Installation: Data Collection Modules (DCM)
This section of the manual will walk the installer through mounting, placement, and installation of the
tab washers and DCM units. Use the following simple rules to aid in placement of DCM hardware.
Rules for Placing DCMs
1. Whenever possible, a DCM should be installed on the container(s) it is monitoring or mounted
on DIN rail.
