§ Check the voltage rating and the plug design
$ The heating unit of the moisture analyzer has been factory-set to 230 or 115 volts for
technical reasons. The voltage has been set as specified on your order. The voltage setting is
indicated on the manufacturer’s label (see the bottom of the analyzer), for example:
– 230 volts: MA50C-...230..
– 115 volts: MA50C-...115..
! If they do not match: To have the voltage setting changed, contact your local Sartorius
office or dealer, and do not operate your moisture analyzer in the meantime!
Use only
– Original power cords
– Power cords approved by a certified electrician/Sartorius service technician
– If you need to connect an extension cord:
Use only a cable with a protective grounding conductor
§ Connecting the moisture analyzer, rated to Class 1, to AC power (mains supply):
The moisture analyzer must be plugged into a properly installed wall outlet which has a
protective grounding conductor (PE)
Safety Precautions
If you use an electrical outlet that does not have a protective grounding conductor,
make sure to have an equivalent protective conductor installed by a certified electrician as
specified in the applicable regulations for installation in your country.
The protective effect must not be negated by using an extension cord without a protective
grounding conductor.
Information on Radio Frequency Interference
Note: This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential
area is likely to cause harmful interference in which case the user will be required to correct
the interference at his own expense. Changes or modifications not expressly approved
by Sartorius AG could void the user‘s authority to operate the equipment.
The AC adapter rated to Class 2 can be plugged into any wall outlet without requiring
any additional safety precautions. The ground or earth terminal is connected to the
housing, which can be additionally grounded, if required. The data interface is also
electrically connected to the scale housing (ground).
Connecting Electronic Devices (Peripherals)
§ Make absolutely sure to unplug the moisture analyzer from AC power before you connect
or disconnect a peripheral device (printer or PC) to or from the interface port.
Warmup Time
To deliver exact results, the moisture analyzer must warm up for at least 30 minutes after
initial connection to AC power or after a relatively long power outage. Only after this time
will the moisture analyzer have reached the required operating temperature.
Using Verified Moisture Analyzers as Legal Measuring Instruments in the EU*:
$ Make sure to allow the analyzer to warm up for at least 24 hours after initial connection to
AC power or after a relatively long power outage
* including the Signatories of the Agreement on the European Economic Area
Charging the Built-in Rechargeable Battery
Before initial operation, leave the moisture analyzer connected to the line current
(mains supply) for at least 10 hours to charge the built-in rechargeable battery. When the
analyzer is disconnected from line current, the analysis data is retained in memory for
approximately three months.
