Connecting the AC Adapter
§ Check the voltage rating on the AC adapter’s type plate. Make sure that the voltage rat-
ing printed on this unit matches the local supply voltage at the place of installation.
§ If the stated supply voltage does not comply with the local supply voltage or there is no
suitable AC adapter available: Do not use the AC adapter.
Contact Sartorius Service.
§ Only use original Sartorius AC adapters.
§ Insert the right-angle plug from the AC adapter into the jack on the electronics module
and tighten the fastening screw
§ Connect the equipment to power:
plug the AC adapter into the wall outlet (mains) at the installation location.
> After connecting the power supply: the LED “RxD/Power” lights up yellow
$ Power is supplied through the DC jack (Hirschmann plug).
If the stated supply voltage or the plug design of the power cord does not comply with
your country's standard, please inform the nearest Sartorius representative or your dealer.
$ Using an AC adapter other than that supplied with the equipment:
The device can be operated with a supply voltage of 12 V to max. 26 V.
! The power connection must be made in accordance with the regulations applicable in
your country.
Safety requirements for operation of the evaluation electronics connected to a safety
extra-low voltage (SELV) source:
The external power supply must meet the requirements of EN 61010-1, Section 6:
Protection Against Shock Current. Please also refer to the specifications for classification
of electrically operated equipment in EN 61010-1.
Safety Precautions:
The power supply must be rated to safety extra low voltage (SELV) or grounded (earthed)
safety extra low voltage (SELV-E).
An AC adapter rated to Class 2 can be plugged into any wall outlet with no additional
safety precautions required. A ground or earth terminal is connected to the housing.
The electronics module must be grounded for operation. The data interface is also
electrically connected (grounded) to the weigh cell housing.
EMC Requirements:
The connector is designed for DC connections between equipment/systems that are not
connected to a DC power supply. The cable length must not exceed 3 m.
To use an external power supply, the power source must meet the requirements of
EN 61326. The following standards apply:
Fast transients IEC61000-4-4
Surge voltage IEC 61000-4-5
Conductive HF signals IEC61000-4-6
Socket, electronics unit Type: G 4 A 5 M
Socket for the above connector Type: G 4 W 1 F, Hirschmann order no. 932157-100
