โ๏ธ Product Introduction
The MAK 1.00.7-36.21.00-51 is a PCB card rack / circuit control panel used in MAK marine engine automation equipment. Available equipment listings identify this drawing number with MAK rack and PCB assemblies, including the 9.01.7-93.11.00-03 module rack platform.
The supplied unit is specifically described as a PCB Card Rack with no back enclosure cover. It is intended to provide the mechanical mounting and electrical interconnection arrangement for compatible plug-in control cards. The associated MAK platform is used in marine diesel engine monitoring and control applications.
The 1.00.7-36.21.00-51 drawing number is also cross-referenced with MAK PCB panel assemblies and controller platforms including 9.01.7-93.11.00-03, 9.01.7-93.01.00-08 and 9.01.7-94.01.00-11.

- The 6.09 kg weight and China origin are published for a MAK rack listing carrying the same drawing number, but should be treated as listing-specific rather than a guaranteed specification for every physical variant.
โ ๏ธ The exact rack dimensions, power requirements, terminal configuration, and supported card count should be verified against the physical rack and original MAK system documentation.
๐ ๏ธ Operating Guidelines
๐น Verify the drawing number before installation: 1.00.7-36.21.00-51.
๐น Check the rack for damaged guides, connectors, mounting hardware, corrosion, or bent contacts.
๐น Confirm that the installed plug-in cards match the intended MAK controller platform.
๐น Make sure the missing back enclosure cover is acceptable for the intended installation. An open or incomplete enclosure may require additional mechanical and safety protection.
๐น Do not insert or remove plug-in cards while energized unless the specific MAK system documentation explicitly allows live replacement.
๐น Check all card positions and wiring before applying power.
๐ง How to Use
- ๐ Identify the existing MAK rack and installed PCB cards.
- โก Switch off and isolate the associated engine control system.
- ๐งค Apply appropriate ESD protection when handling electronic cards.
- ๐งฉ Install the compatible PCB cards into their designated rack positions.
- ๐ Check all backplane and external wiring connections.
- ๐ก๏ธ Confirm that the rack is mechanically secured.
- โก Restore system power.
- ๐ฅ๏ธ Allow the MAK control system to initialize.
- ๐จ Check for card, communication, or system faults.
- โ Perform the approved engine-control functional test before returning the system to service.
๐ Power-On Sequence
- ๐ Inspect the rack and all installed cards.
- ๐งฐ Confirm that the rack is securely mounted.
- ๐ Check connectors and wiring.
- โก Energize the main MAK control-system power supply.
- ๐ฅ๏ธ Allow the controller and plug-in cards to initialize.
- ๐ก Verify communication and diagnostic status.
- ๐จ Check for abnormal alarm or fault indications.
- โ Confirm normal control-system status before enabling the controlled equipment.
โ Power-Off Sequence
- Notify the responsible operator or maintenance engineer.
- Place the engine/control system in the approved safe condition.
- Stop the associated process according to the vessel’s operating procedure.
- Shut down the MAK control system normally where applicable.
- Isolate the rack power supply.
- Verify that the rack is de-energized before removing cards.
- Use ESD protection during card removal or replacement.
โ ๏ธ Never assume that a PCB rack is safe to remove or service simply because the engine is stopped. External and backup power sources may still be present.
๐ Product Usage Notes
This rack is a mechanical and electrical infrastructure component, not a standalone PLC or engine controller. Its correct function depends on the PCB cards installed in the rack and the surrounding MAK control architecture.
The same drawing number is associated with MAK rack assemblies containing plug-in modules. One available listing identifies 9.01.7-93.11.00-03 as a module-rack component and gives 1.00.7-36.21.00-51 as the drawing number.
Related MAK documentation also identifies plug-in cards from the 9.01.7-93 and 9.01.7-94 families as components of engine safety/control equipment.
Because this particular unit has no back enclosure cover, inspect the intended installation carefully. The missing cover may affect physical protection, environmental protection, and safe maintenance access.
โ Common Questions & Answers
Q: What is MAK 1.00.7-36.21.00-51?
A: It is a MAK PCB card rack / circuit control panel used for mounting and interconnecting compatible plug-in control cards.
Q: Is it a PLC CPU?
A: No. The rack itself is not a standalone CPU. It provides the rack/backplane structure for compatible MAK electronic modules.
Q: What equipment is it used with?
A: It is associated with MAK marine engine monitoring and control equipment and 9.01.7-series controller platforms.
Q: Does this unit include the back enclosure cover?
A: No. The supplied description specifically states that the rack has no back enclosure cover.
Q: Can I install any MAK PCB card in this rack?
A: No. Card compatibility depends on the rack configuration, controller platform, wiring, and system application.
Q: What should I check before purchasing?
A: Check the drawing number, rack construction, card guides, connectors, mounting points, condition of the backplane, and the absence of the rear enclosure cover.
Q: What is the approximate weight?
A: A listing for the same drawing number gives approximately 6.09 kg. This should be confirmed for the actual unit before shipping calculations.
Q: Is 1.00.7-36.21.00-51 a PCB itself?
A: The number is used as a drawing number for MAK PCB rack/panel assemblies. The physical item may therefore be a rack or panel assembly rather than an individual electronic plug-in card.
Q: Can the rack be operated without the rear cover?
A: It may be possible for testing or storage, but for permanent installation the enclosure and protection requirements of the original system should be followed.
Q: Is this suitable for marine engines?
A: Yes. MAK equipment in this family is associated with marine diesel engine monitoring and control applications.
