Installation Instructions
BMZ Series Fuse Holder
Part Number: 0FHZ00853-BX & 0FHZ00854-BX
Installation
Assemble the fuse holder and mount to the battery terminal in the following sequence:
1.
Place the battery terminal clamp over the center bolt. 2/3-way bus bar needs to be assembled. Insert bolt for 2-way
or center stud for 3-way through the bottom of the bus bar. Secure the nut for the 2-way or place the highest rated
fuse for the 3-way to secure the clamp to the busbar.
2.
Place the appropriate ZCASE fuses (M8) onto the isolated studs. On the 3-way bus bar the highest value fuse should
be put in the center position to minimize the length of the electrical path.
•
When selecting fuse values, the continuous current through a fuse should be calculated per the Time Curve
found in our ZCASE Datasheet. Littelfuse.com/ZCASE_Datasheet
•
The total long-term continuous current for all fuses should not exceed 275A.
•
Intermittent loads (motor start, starter or compressor) should not exceed 400A for 20 seconds.
3.
Place an appropriately sized output cable with an M8 or 5/16" terminal on the top of the ZCASE fuses. Place the
included M8 nuts on the isolated stud. Torque the nuts to 14Nm±2Nm. Be sure to hold the wire and terminal while
applying torque to prevent twisting which can damage the fuse element from excessive torque.
4.
Place the tail end of the cover onto the positive battery post, with the inside of the cover facing upwards. Place the
fuse holder assembly over the battery post and tighten to 5.4Nm± 0.9Nm. Press the red rubber cover down over the
studs and nuts.
5.
Be sure the output cables are routed so they have sufficient bend radius and are not at risk of being damaged or
pinched. Make sure that all cables are strain relieved by being supported within 18" of the battery.
