Risk of electric shock. 110-240 Volts may be present.
Work on electrical parts of the system must be performed only by trained
electricians! If the insulation is damaged, switch off the voltage supply
immediately and have the system repaired by a trained electrician! Keep
moisture away from electrical component parts. Moisture may cause
short circuits. The improper installation of parts or improper handling of
electrical systems may lead to personal injury and risks to life.
Risk of connecting the applicator to an electical system that is not
suitable for using the appliance safely.
HERMA 400 applicators are designed for connection to and operation on a
TN-C-S electrical system. Appropriate technical measures must be taken
before use on other types of electrical system.
TT system: For a TT system, the earthing/electrical bonding must be
installed according to the applicable national regulations.
IT system: For an IT system, appropriate safety measures must be taken
and the electrical bonding must be installed according to the applicable
national regulations.
Improper handling of electrical systems may lead to personal injury and
risks to life.
If there is a malfunction at the applicator it is appropriate to cut it off from
the mains supply to have it stopped and avoid unforeseen action. The
applicator/machine must have a mains disconnection device to cut off
the mains supply in case of malfunction. Otherwise this could lead to
serious injury.
Only connect the applicator to AC voltage, and check whether your mains
voltage complies with the voltage specification on the nameplate.
Only connect the applicator to a properly installed, earthed power socket
or connect it appropriately in the control cabinet of the relevant machine.
The applicator/machine must have a mains disconnection device to cut
off the mains supply in case of malfunction.
Work on electrical components shall only be performed by authorised
specialists and in observance of the relevant safety regulations.
Disconnect the applicator from the mains before working on the parts of
the electrical equipment.
When you disconnect the HERMA 400 applicator from the mains, wait at
least five minutes before opening the housing or touching the connector
pins. Residual voltages could be present!
Mount the applicator appropriately before energy is supplied.
Due to several sensors at the applicator unforeseen movements could
result if sensors get covered / uncovered unintendedly. Switch the
applicator off before changing the label roll. Otherwise this could lead to
injuries.
