Installation Instructions
MiniFlec Series Power Distribution Module
Part Number: LFMX0007Z-01
Description
The standard MiniFlec is a compact, front access, internally
bussed, connectorized, sealed power distribution module,
suitable for mounting in rugged commercial vehicle
applications. The MiniFlec is a product that has dense
concentration of high power circuits and accepts plug devices
like automotive fuses, diodes and relays to protect and control
complex electrical systems. An internally mounted Printed
Circuit Board (PCB) allows bussed connections to a large
number of devices.
Installation
Assemble the PDM and mount to a surface following the
below sequence:
1. Fill the available fuse and relay spots to match the the
application needs. Check the locations on the fuse and
relay table for the maximum fuse and relay ratings for
each space and do not exceed the maximum rated values.
2. Use the mounting hole pattern on the mounting surface
and mark the mounting hole pattern. Drill the holes so
they are sized for M6 bolts. Place the MiniFlec over the
pattern and bolt it in place. Torque down the mounting
screws to 12-15Nm (4.5-5.9 ft-lb).
3. The harnesses should be made to match the terminal
map on the schematic. The connectors should now be
attached. Each has a unique key that should prevent
misassembly. Make certain that the connectors are fully
inserted and the secondary lock is fully engaged. If the
secondary lock will not fully engage, the connector is not
fully connected. Be sure that the output cables are routed
so they have sufficient bend radius and are not at risk
of being damaged or pinched. Lastly, make sure that all
cables are strain relieved by being supported within 18”
of the battery.

DETAILS
Fill in all fuse locations with application specific
fuses make sure not to exceed the maximum value
for the fuse locations as listed in fuse table. Fill the
application specific relays using the recommended
types of relays. There is a location on the inside
cover to place a fuse identification label. We
recommend you add a label here to help with
maitenance and troubleshooting. Replace the cover
and snap on the AssureLatch latches. If you do not
get positive tactile and audible feedback that the
latches are fully seated, check the position of the
cover. The box is only seated correctly and sealed
when laches are properly snapped into place.
