Closing the Combics Indicator
tRe-attach the front panel and secure it with the 10 cap nuts.
Connecting the Device to AC Power
The indicator is powered through the pre-installed power cord.
The power supply is integrated into the indicator.
The device can be operated with a supply voltage of 100 to 240 V.
3The power connection must be made in accordance with the regulations applicable in your
country.
Make sure that the voltage rating printed on the manufacturer's ID label is identical to that
of your local line voltage. If the voltage specified on the label or the plug design of the AC
adapter do not match the rating or standard you use, please contact your Sartorius office or
dealer.
tCheck the voltage rating and plug design.
tThe device must be plugged into a properly installed wall outlet.
Protection Class 1 Device
tThe device must be plugged into a properly installed wall outlet which has a protective
grounding conductor (PE).
Safety Precautions
3If you use an electrical outlet that does not have a protective grounding conductor, ensure
that an equivalent protective conductor is 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.
Before using for the first time, any superstructure parts must be completely installed.
Avoid connecting the equipment to lines that have a heavy electrical load, e.g. compressors,
large machinery, etc.
Warm-up Time
To deliver exact results, the device must warm up for at least 30 minutes after connection
to AC power. Only after this time will the device have reached the required operating
temperature.
Using a Verified Device in Legal Metrology
Ensure that there is a warm-up time of at least 24 hours after connection to the power
supply.
