Electrical connection
The 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 10.4).
►
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.
Device connection:
The device is connected by a mains plug (see
→
Chapter 2.2).

The power supply cables and the main switch
(device-specific) are located on the device.
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 damage
due to a faulty electrical
connection.
►Load shedding circuits or device shutdowns are
not permitted.
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.
►Observe applicable local regulations
(e.g. for the electric installation and
operation of the device).
►Follow the applicable standards and
safety instructions.
►Never connect more than one device to
a miniature circuit breaker or a residual
miniature combination switch (RCBO).
Exception, device type AC-S, AC-M, AC-
W (220-240V 50Hz): Never connect
more than two devices to a miniature
circuit breaker or a residual miniature
combination switch (RCBO).
One of the following electrical fuses must be used:
Circuit breaker (CB) in combination with residual
current circuit breaker (RCCB/GFCI).
FI-LS combination switch (residual current breaker
with overcurrent protection, RCBO).
Observe the applicable standards such as:
VDE 0100-410
ÖVE/ÖNORM E 8001-1/A1
NEC 70
NBR 5410
8 Commissioning
The device must only be commissioned in the
intended installation room and after checking for
completeness. The operating company can carry out
the commissioning.
WARNING
Damage to the electrical system and/or the
refrigerant circuit. Contact with live parts
may cause electric shock. The refrigerant
can escape and create an explosive gas/air
mixture. Risk of fire due to sparks or
overloading.
►Do not commission a damaged device.
►Do not connect damaged parts (such as
power cords) to the circuit.
►Damaged parts (such as power cords)
must only be replaced by qualified staff.
►Observe the special safety and warning
information for devices with flammable
refrigerants (see
→
Chapter 1.6.2.1).
►In event of damage, contact the
maintenance service (see
→
Chapter 10.4).
