For some devices there is an overview of spare part sets inside the device. If the spare part set is listed there, the verification
is not required.

1. www.endress.com/deviceviewer

2. Enter serial number (Ser. No.), search for product data and click
on "spare parts".

3. List of all spare parts sets for the device.

4. Determine the order number of the spare part set.

The spare part set can only be used if the order number of the



spare part set corresponds to the order number on the spare part
list.

Authorization to carry out a repair depends on the approval of the measuring device. The table shows the respective group of
persons for each.

The person who carries out the repair is responsible for safety during the work, the quality of work completed and safety of
the device after repair.

replace a faulty unit with a functioning unit of the same
type.
Use genuine parts from Endress+Hauser only.

• Comply with national regulations governing mounting,

electrical installation, commissioning, maintenance and
repair procedures.

• Requirements with regard to specialized technical staff for

the mounting, electrical installation, commissioning,
maintenance and repair of the measuring devices:
– trained in instrument safety.
– familiar with the individual operation conditions of the

devices.

– for Ex-certified measuring devices: also trained in

explosion protection.

• The measuring device is energized. Danger: Risk of electric

shock! Open the measuring device in a de-energized state
only.

• In the case of Ex-certified measuring devices: Only open in a

de-energized state (once a delay of 10 minutes has elapsed

1)

after switching off the power supply) or in environments
which do not have a potentially explosive atmosphere.

• In the case of measuring devices in safety-related
applications in accordance with IEC 61508 or IEC 61511:
After repair recommission in accordance with Operating
Instructions. Document the repair procedure.

• Before removing the device: set the process in a safe
condition and purge the pipe of dangerous materials.

• Hot surfaces! Risk of injury! Before commencing work, allow
the system and measuring device to cool down to a
touchable temperature.

• In the case of measuring devices in custody transfer, the
custody transfer status no longer applies once the lead seal
has been removed.

• Follow the Operating Instructions for the device.

• Risk of damaging electronic components! Ensure you have a
working environment protected from electrostatic discharge.

• After removing the electronics cover, there is a risk of
electric shock as shock protection is removed!

compartments) must be lubricated. Use an acid-free, non­hardening grease if an abrasion resistant dry lubricant is
non-existent.

• If spacing is reduced or the dielectric strength of the
measuring device cannot be guaranteed during repair work,

perform a test on completion of the work (e.g. high-voltage
test in accordance with the manufacturer's instructions).

• Service connector:
– Do not connect in potentially explosive atmospheres.
– Only connect to Endress+Hauser service devices.

• Observe the instructions for transporting and returning the
device outlined in the Operating Instructions.

If you have any questions, contact your

Endress+Hauser service organization.

Tools list

For applications in custody transfer

The NXA83B is a device that is suitable for custody transfer measurement. According to international custody transfer
regulations, the device can be approved and sealed by an official for legal metrology controls after device commissioning.

• It is necessary to break the seal if a spare part needs to be replaced. The authority for legal metrology controls must be
notified of this within 24 hours.

• Once the spare part has been replaced, an official must approve and seal the NXA83B device once more.

Replacing input and output cards

Always make sure to de-energize the device before replacing any spare parts.

NOTICE

After the part has been replaced, the plug-in connections on the back of the device must be restored to their original state,
as the proper operation of the device cannot be guaranteed otherwise.

Mark the plug-in connections on the back of the housing.

‣

Install input and output cards in the original slot.

‣

The input and output cards require a supply voltage of 5 VDC, only the Sakura V1 input card requires 5 VDC and 12 VDC in
addition.

The procedure for replacing the input and output cards depends on the device design. The procedure for replacing cards in the
case of a wall-mount housing and a 19" rack is described below.
