Qblox instruments are sensitive pieces of equipment, which should not be opened under any circumstances. The Cluster contains high-voltage parts which are dangerous. The end user shall not install substitute parts or perform any modification to the product. Opening the instruments immediately voids the warranty provided by Qblox.

The safety instructions listed below should be observed during all operating procedures. Ignoring this might affect correct operation and lifetime of the equipment.



Maximum ratings

The specified ratings for the connectors of the equipment should not be exceeded.

Do not service the instrument

There are no serviceable parts inside the equipment. Only the battery of a module is allowed to be replaced by the user.


Warnings issued by the software should not be ignored, look for instructions on how to handle these warnings in the documentation.

Location and ventilation

When placing the equipment, make sure the air in- and outlets are kept free from obstruction to allow sufficient air to cool the devices. If there is other equipment with ventilation nearby, make sure that the ventilation requirements do not interfere.


Disconnect the power supply from the equipment before cleaning. The outside of the device can be cleaned using a soft cloth. Do not clean the inside.

Operation and storage

Do not operate and store the equipment outside the specified conditions.


Beware! The modules can still be hot when extracted from the cluster in case the instrument was running shortly before extraction.


Cluster instruments are meant for indoor use only. The cluster can be mounted into a 19” rack or as desktop device.

The device should be positioned in such a way that the disconnecting device is easily reachable.

When placing the equipment make sure the air in and outlets are kept free from obstruction to allow sufficient air to cool the devices. In case the Cluster is mounted in a 19” rack one should make sure the total amount of air allowed to flow is sufficient for all devices together. Other equipment installed in the same rack with ventilation requirements should not interfere with the ventilation requirements of the Cluster.

SMA connections#

The SMA connectors should be fixed with a maximum torque of 0.55 Nm. A torque wrench should be used to make sure the maximum is never exceeded. Note that using a torque wrench at an angle will cause it to exceed the rated torque considerably.

Ethernet connection#

The ethernet should always be connected with a shielded category 5 or 6 ethernet cable. For optimal performance, use the included Cat6 S/FTP cables or similar ones.

Unusual conditions#

If any of the conditions listed below are noticed, please power down the equipment immediately and contact the Qblox support team.
