Intended use

The electronic AC•THOR 9s Photovoltaic-Power-Manager (in the following, AC•THOR 9s 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 9s 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 9s is designed for fixed installations indoors.
Installation in rooms with a high level of humidity must comply with relevant regulations!
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 9s 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!). All connected devices must be operated with phase and neutral conductor.
Never connect 400V loads without neutral conductor!
Otherwise this may cause damage to the AC•THOR 9s or to the other loads connected to it.
Only the supplied plugs must be used for connection!
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.
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!
Installation in rooms with a high level of humidity must comply with relevant regulations!
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 9s must be connected to a nominal voltage of 3 x 230 VAC, 50/60 Hz. The neutral conductor is absolutely necessary!
Protection of the mains connection for the AC•THOR 9s may not exceed 16A per phase (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

Connections

MY-PV-AC-THOR-9s-Power-Manager-fig-2

Modbus RTU connection for external control

Use shielded twisted pair wire!
RTU bus must be equipped with a 120 Ohm termination resistor! (Not included in the scope of delivery)
When controlling via Modbus RTU, the operating mode M7 cannot be used!

Assembly

Remove the wall bracket from the rear of the AC•THOR 9s unit. To do this, slide the lock underneath to the right.

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. MY-PV-AC-THOR-9s-Power-Manager-
fig-5

To fix it to the wall bracket, the AC•THOR 9s 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 9s is securely fixed!
When installing in an electrical cabinet, ensure sufficient cooling, for example through ventilation slots in the switch cabinet door!
A minimum lateral distance of 7cm must be observed!
When installing several devices side by side, a minimum distance of 10cm must be observed!
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 9s. 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 9s may not exceed 16A per phase (tripping characteristic B or C).
The PE conductor and the neutral conductor must be connected!
Pay attention to other loads on the line circuit, this may trip the circuit breaker!
The conductor cross-sections at the mains connection and at the load connections must be at least 2.5 mm².

Operation on one or two phases

The device is also suitable for operation on one or two phases.
Phase L1 must be connected (power supply).
In order to guarantee a perfect control function, outputs whose corresponding phase is not supplied on the input side must not be connected!
L1 IN → Out1
L2 IN → Out2
L3 IN → Out3

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 power supply is off, 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 the possibilities for setting will be found in the Operating instructions for the unit. The current version is available on www.my-pv.com.

Troubleshooting

The device does not contain any parts that may be repaired by the user. In the event of a fault, please contact your specialist dealer.

Disposal

Packaging material must be either stored or disposed of as appropriate. Dispose of the product at the end of its service life according to the statutory regulations.
