WARNING!
Risk of injury in case of missing or faulty protective
equipment.
After performing maintenance work, attach all safety
equipment (covers, safety precautions, ground cables
etc.).
Replace faulty parts and those which have become
unusable.
The printer is designed for power supply systems from
110 … 230 V AC. Connect the label printer only to electrical outlets
with a ground contact.
Couple the label printer to devices using extra low voltage only.
Before making or undoing connections, switch off all devices involved
(computer, printer, accessories etc.).
Operate the label printer in a dry environment only and do not get it
wet (sprayed water, mist etc.).
Maintenance and servicing work can only be carried out by trained
personnel.
Operating personnel must be trained by the operator on the basis of
the operating manual.
If the label printer is operated with the cover open, ensure that
clothing, hair, jewellery and similar personal items do not contact the
exposed rotating parts.
The print unit and parts of it (e.g. printhead) can get hot during
printing. Do not touch the printhead during operation. Cool down the
print unit before changing material, removal or adjustment.
Never use highly inflammable consumables.
Carry out only the actions described in these operating instructions.
Any work beyond this may only be performed by the manufacturer or
upon agreement with the manufacturer.
Unauthorized interference with electronic modules or their software
can cause malfunctions.
Other unauthorized work or modifications to the direct print module
can endanger operational safety.
Always have service work done in a qualified workshop, where the
personnel have the technical knowledge and tools required to do the
necessary work.
There are warning stickers on the direct print modules that draw your
attention to dangers. Therefore the warning stickers are not to be
removed as then you and others cannot be aware of dangers and may
be injured.
DANGER!
Danger to life and limb from power supply!
Do not open the casing.

2.2 Safety Handling when Working with Electricity
The following work may only be performed by instructed and
trained electricians:
•work on the electrical assemblies
•work on the device while it is open and connected to the
power supply.
Locate the emergency-stop or power switch so that it can be
actuated in case of an emergency.
Unplug the device from the electrical outlet before performing
the following work:
•removing or installing power supply units
•working in the immediate vicinity of exposed power supply
parts
•mechanical inspection of power supply parts
•modifying the device circuits.
Ensure that the device is de-energized.
Check the workplace for possible sources of danger, e.g. moist
floors, defective extension cables, faulty protective conduction
connections.
Give another person the task of remaining near the workplace.
This person must be familiar with the location and operation of
the emergency-stop and power switches and switch off the
power if danger arises.

respective task.
Proceed in a very cautions and calm manner.
Avoid endangering yourself.
Switch the power off.
Request medical help (emergency physician).
Call for first aid if necessary.
