Low-Current 20/20 GMT Series Fuse Panels
Power :: Models 06004-01 & 06004-11 Installation Guide
2
GMT output fuses are available in capacities ranging from 0.18A to 10A. GMT splash covers are optional for maximum
safety when fuses blow. (Visit our website at www.telect.com or see Section “1.6 GMT Fuses” on page 12 for ordering
GMT fuses.) The panel is delivered with “dummy” fuses in all positions.
The standard front panel includes a tri-color fuse alarm LED for each circuit (ALARM A and ALARM B):
• The ALARM LEDs are green when all installed input and output fuses are operational
• The ALARM LED is red when any output fuse blows
• The ALARM LED is orange when either of the input fuses blows
The back contains input and output terminal connections (NEG connections at top; POS RTN connections below),
chassis ground connections and wire-wrap pins for external alarm hookups.

Model 06004-11 includes a fail-safe circuit. Schottky diodes are cross-connected at the input to the power distribution
circuits. When both power supplies are energized, power is balanced between the two supplies by the diodes. If one of
the power supplies loses its power or is shut down, the other supply shares its power with both outputs (A and B) through
the Schottky diodes. The positive battery return circuits for A and B are common since both circuits must operate from
either the A or B power source. The fail-safe feature limits the A and B inputs to 15A maximum for each bus (total 30A
per panel).
NOTE: For the Fail Safe load sharing to function properly, the capacity of each of the user-supplied external feeder fuses
or breakers must be greater than the total load of the panels A and B outputs combined. For example, if the panel’s total
Load A = 10A and Load B = 10A, then the feeder fuse for Side A and Side B must each be at least 20A.
