Electrical connection
The connection to the power supply is provided by the
operator. For technical data, see
→
chapter 2.2.
WARNING
Connect the unit to the power supply.
Contact with live parts may cause electric
shock. Risk of fire due to sparks or
overloading.
►
Work on the electrical system may only be
performed by qualified staff.
►
Refer to the local electrical safety
regulations.
►
Follow the applicable standards and
safety instructions.
►
Follow the information on the serial plate
(see
→
chapter 2.2.1). The network voltage
and the network frequency must match the
specifications on the serial plate.
►
Do not connect any damaged unit to the
power circuit.
►
Damaged parts (such as power cords)
must only be replaced by trained staff.
Contact the maintenance service (see
→
chapter 10.4).
►
Do not squeeze or bend power supply
cords.
►
Observe the minimum requirement for
connection cables (see
→
chapter 2.2).
►
The unit must be electrically protected
according to the applicable laws and
regulations and the requirements of AHT
(see
→
chapter 7.2).
►
Connect the unit only to a network circuit
with protective grounding.
►
Do not use extension cords or multiple
power strips.
►
Concealed electrical parts must not be
damaged. Drilling or other work on the
device is not permitted.
NOTICE
•
Material and property damage
caused by non-
AHT-approved deviations (voltage, frequency) in
the operator's electrical network.
►
The manufacturer is not responsible for damage
to the electrical unit of the operator and the
subsequent damage caused thereby.
•
Material and property damage
due to a wrong
electrical connection.
►
Load shedding circuits or device shutdowns are
not permitted.
Unit-connection cable
At the end of the unit-connection cable you can find a
labeling flag with a snowflake.

The unit-connection cable is used for cooling
purposes.
NOTICE
•
Property damage
due to missing connection
(cooling).
►
Do not connect the unit-connection cable to the
power supply of the ambient light.
Light-connection cable (optional)
At the end of the light-connection cable you can find
a labeling flag with a lamp.

Unit/Light- connection cable:
No labeling flag.
NOTICE
•
Property damage
due to missing connection
(cooling).
►
Unit/Light- connection cable requires permanent
power supply.
Units with IEC-Box
For technical data, see
→
chapter 2.2.
Units can be equipped with a so-called IEC-Box.
Fig.6: IEC-Box
WARNING
Wrong electrical connection to the IEC-Box.
Contact with live parts may cause electric
shock. Risk of fire due to sparks or
overloading.
►
The brackets of the IEC-Box must be
properly fixed and secured by the screw holder
(see
→
Fig.6).
AHT recommends (e.g. island arrangement) the
usage of a cable duct with internal or external
sockets. In the case of floor mounting, do not exceed
lower edge of the ventilation grille on the backside.
Electrical protection
Each electrical supply circuit must be equipped with
appropriate protection means according to National
requirements and local regulations.
For technical data, see
→
chapter 2.2.
WARNING
Faulty/inadequate electrical fuse.
Contact with live parts may cause
electric shock. Risk of fire due to sparks
or overloading.
►
Provide adequate protection.
►
Observe applicable local
requirements (for example, for electrical
installation and operating of the device).
►
Follow the applicable standards and
