Electrical connection
Connection to the power supply is carried out by the
operating company. For technical data, see
→
Chapter 2.2.
WARNING
Connect the device 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 power rating
plate (see
→
Chapter 2.2.1). The network
voltage and the network frequency must
match the specifications on the power rating
plate.
►Do not connect any damaged devices to
the circuit.
►Damaged parts (such as power cords)
must only be replaced by qualified staff.
Contact the maintenance service (see
→
Chapter 10.5).
►
Do not squeeze or bend power supply
cords.
►Observe the minimum requirement for
connection cables (see
→
Chapter 2.2).
►The device must be electrically protected
according to the applicable laws and
regulations and the requirements of AHT
(see
→
Chapter 7.2).
►Connect the device 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.
NOTE
•
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 device of the operator and any
subsequent damage caused thereby.
•
Material and property damage
due to incorrect
electrical connection.
►Load shedding circuits or device shutdowns are
not permitted.
Device connecting cable
A labeling tag with the snowflake is located at the end
of the connecting cable.
Fig. 9: Snowflake symbol
The device connecting cable is used to supply the
cooling unit.
NOTE
•
Property damage
from switching off the cooling unit.
►Do
not connect
the device connecting cable to
the power supply for the market light.
Light connecting cable
A labeling tag with the lamp symbol is located at the
end of the connecting cable.
Fig. 10: Lamp symbol
The light connecting cable offers the option to switch
off the device lighting together with the market
lighting (saving energy).
Combined device / light connecting cable:
No labeling tag.
The combined device / light connecting cable
is used
for the common supply of the cooling and lighting.
NOTE
•
Property damage
from switching off the cooling unit.
►Connect the device / light connecting cable
to a
voltage supply that is permanently supplied with power.
Device with IEC box
For technical data, see
→
Chapter 2.2
Devices can be equipped with an IEC box in
combination with plugged connecting lines (see Fig.
11).
Fig.11: Connection with IEC box
WARNING
Faulty electrical connection on the IEC box.
Contact with live parts may cause electric
shock. Risk of fire due to sparks or
overloading.
►The bar of the IEC box must be fixed
correctly and secured by the screw holder (see
Fig.11).
ANT recommends (e.g. with block installation) the
use of a cable duct with installed or mounted sockets.
In the case of floor assembly, the height of the cable
duct must reach no higher than the lower edge of the
rear venting grille.
Electrical protection
Each device must be equipped with an electrical
fuse.
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.
