Inspection and maintenance
8.1
Safety instructions
– Prior to performing any work on the PSM MID measuring module, the unit must be disconnected from
the power supply and protected against being
switched on again.
– The unit does not need to be opened and so prohibited.
8.2
Work to be performed
8.2.1 Inspection
The system must be checked regularly for its complete correct functioning. Rittal recommends a regular
function test when required. The intervals between the
tests should be no longer than one year.
8.2.2
Cleaning
Note: Risk of damage!
Do not use aggressive substances such
as cleaner's naphtha, acids, etc., for
cleaning as they may cause damage to
the plastic surface.
„ Clean the unit in regular intervals using a lightly
moistened cloth.
8.2.3 Maintenance
Because the unit is largely maintenance-free, the
maintenance of the unit is largely limited to the "inspection" and "cleaning" tasks.
8.2.4 Recalibration
After expiration of the calibration end date printed on
the measuring module, the unit must be recalibrated if
it is still to be deployed for billing purposes.
„ If necessary, contact Rittal for a recalibration of the
unit.
8.2.5 Test procedure
To test the unit, an adaptor kit can be obtained from
Rittal (see section 13 "Customer service addresses").
With this adaptor kit, under reference conditions on a
suitable calibration rig (normally obtainable from a
standards bureau), the flashing rhythm of the LEDs,
and so the complete unit, can be tested using the MID
displays (fig. 4, item 2 or item 9).

Storage and disposal
9.1
Storage
EN
If the device is not used for a long period, Rittal recommends that it is disconnected from the mains power supply and protected from dampness and dust.
9.2
Disposal
Because the PSM MID measuring module consists
primarily of the "housing" and "circuit board" components, the device must be sent to the electronic recycling for disposal.

Testing and rectification
10.1 Wrong cable combination
This error message is displayed when you use different types of connection cables for the inputs and outputs on a PSM MID measuring module (e.g. a 32 A
variant at the input and a 16 A variant at the output).
„ Ensure that you use only the appropriate connection
cables on a PSM MID measuring module.
10.2 Wrong cable type
This error message is displayed when you use incorrect connection cables on a PSM MID measuring
module (cables for the 32 A variant on a 16 A device
or cables for the 16 A variant on a 32 A device).
„ Ensure that you use only the appropriate connection
cables on a PSM MID measuring module.
10.3 Other possible error sources
Under some circumstances, one of the two abovementioned error messages is displayed although you
have used the correct connection cable. This can be
the case when the voltage supply to the device at the
"Infeed 1" connection has already been established
and you then want to connect further cables.
„ In this case, disconnect the voltage supply to the
PSM MID measuring module.
„ Connect all required cables.
„ Finally, establish the voltage supply at the "Infeed 1"
connection.
Alternatively, you can also acknowledge the error
message by briefly changing the circuits in the configuration menu.
„ Change the "Disp. Circuit" setting in the configuration menu to "Source 1" (see section 7.4.1 "Settings
using the configuration menu").
„ Then change the "Disp. Circuit" setting to the appropriate entry for the actual connection configuration.
