AC•THOR®Assembly Instructions, Version 180604 3
Intended use
The electronic AC•THOR Photovoltaic-Power-Manager (in the following, AC•THOR for short) is
designed for operating resistive loads such as electric immersion heater elements, electric
boilers, electric convectors, electric heating mats or infrared panels.
The unit controls the output voltage according to external signals (temperatures, Ethernet- and
other control signals) linearly and thus the power output of the connected load.
The AC•THOR is controlled by the my-PV Power Meter or can be combined with products of
different manufacturers (the current list of manufacturers can be seen under www.my-pv.com).
The AC•THOR is designed for fixed installations indoors.
In sanitary facilities, the relevant regulations must be observed!
Any application other than those described above may cause damage.
Furthermore, this may lead to hazards such as a short circuit, fire, electric shock, etc. The safety
instructions and the information on handling in this manual and in the operation instructions
shall be followed!
The product complies with the statutory, national and European requirements. The names of
the company and products are trademarks of my-PV GmbH. All rights reserved.
You will find a comprehensive description of the unit's functions and potential settings
using the display or via web interface in the online Operating instructions.

Safety instructions
The AC•THOR is designed for fixed installations indoors.
The connected units may only be pure resistive electric loads such as immersion heater
elements, boilers, convectors, heating mats or infrared panels! The units connected must
be suitable for variable supply voltages between 0-230 V AC (in no circumstances units
with electronic power supply) as this otherwise may cause damage to the AC•THOR or to
the other loads connected to it.
Only connect loads fitted with suitable mains plugs to the load socket!
In cases where the load to be connected has no mains plug, a 16 A earthed EURO mains plug
must be fitted (not supplied).
Operation of heating systems incorporating electronic thermostats is not possible!
For heating water, only heaters with an integral safety temperature limiter may be connected.
Installation must be carried out by an accredited specialist.

AC•THOR®Assembly Instructions, Version 180604 4
Comply with the relevant standards when mounting and connecting the device.
The unit housing may heat up during operation. Only mount the unit on non-combustible
surfaces.
The unit is only intended for use in dry rooms indoors. Otherwise there is a risk of fatal electric
shock!
In sanitary facilities, the relevant regulations must be observed!
Do not install the device in an environment contaminated with ammonia.
Do not install the device in a dusty environment.
The ventilation holes of the housing must not be covered.
Avoid exposure to high temperatures (> 40°C), low temperatures (< 5°C) or direct sunlight
during storage and operation.
The AC•THOR must be connected to a nominal voltage of 230 V AC, 50 Hz.
Protection of the mains connection for the AC•THOR may not exceed 16 A (tripping
characteristic B or C).
The accident prevention regulations established by the German Employer's Liability Insurance
Association for electrical equipment and facilities must be adhered to in commercial facilities.
This unit can be used by children ages 8 and persons with reduced physical, sensory or mental
capabilities or lack of experience and knowledge if they have been given supervision or
instruction concerning the safe use of the equipment and understand the resulting risks.
Children should not play with the appliance. Cleaning and user maintenance shall not be
undertaken by children without supervision.
Limitation of warranty and liability
A limitation of warranty and liability applies for:
any damage or injury caused by improper handling or failure to observe the assembly and
operating instructions
Consequential damage, in particular to the connected loads
Altering, disassembling or otherwise intervening in the device or making changes to the
device without authorisation

Assembly
A brief video (German) to explain assembly will also be found online:
https://www.youtube.com/watch?v=WFHbayf5VDQ
Remove the wall bracket from the rear of the AC•THOR unit. To do this, slide the lock
underneath to the right.

AC•THOR®Assembly Instructions, Version 180604 6
Then fix the wall bracket to the wall with three screws. Three screws and three wall-plugs are
supplied. If the screws supplied are not suitable for the substrate, suitable screw must be
obtained.
To fix it to the wall bracket, the AC•THOR is suspended in the wall bracket by the two long slots
on top and then fixed in place by locking it underneath (slide to the left).
Check the AC•THOR is securely fixed!
Then the electrical connections can be made.
Do not immerse my-PV temperature sensor(s) directly in water. Use a thermowell!
TIP: For mains leads, use a cable duct with a depth of 60 mm.
The necessary cut-out measures 130 x 60 mm.

Connecting several temperature probes
Up to four digital temperature probes (three-core, bus system) can be connected to the
AC•THOR. The terminal positions for the three cores are shown in the following illustration.
TIP: If more than one probe is used, the cores can also be connected externally
in parallel!
Electrical connection
Protection of the mains connection for the AC•THOR may not exceed 16 A (tripping
characteristic B or C).
The PE conductor of the socket must be connected!
Pay attention to other loads on the line circuit, this may trip the circuit breaker!
The AC•THOR is controlled by external signal sources by way of IP protocol using a standard
Ethernet RJ45 cable.
Electrical connection for multiple units
All devices should be connected to appropriate AC circuits. Note that each AC•THOR takes up to
3 kW power (with relay output up to 6 kW). It makes sense to divide this between the phases on
the grid.

Maintenance
Do not attempt to open the unit. The device does not contain any parts that may be
repaired by the user.
Never splash water on or in the unit!
When it is unplugged, the surface of the unit can be cleaned either with a damp cloth, using
mild glass cleaner or cleaning tissue for glasses.
In a polluted environment, the air inlets and outlets should be checked regularly for cleanliness.
If necessary, the unit can be cleaned through the air slots with a vacuum cleaner.
The unit cannot work at maximum efficiency if the air supply is inadequate!
If the mains cable of the unit is damaged, it has to be replaced by the manufacturer or its
service agents or a similarly qualified person.
Operation displays
The unit has a touch screen to show operating conditions and for ease of operation.
Never touch the screen with pointed objects or those having sharp edges!
For best use the supplied operator stylus. The holder for the stylus can be stuck on to a surface
on or close to the unit with the adhesive patch.
A detailed description of the graphic user interface, the operating modes, the menu guide and
