4. Electrical safety instructions

All Fohhn products that are or contain Fohhn power amplifiers are protection class 1 appliances. They are built and certified in accordance with
the VDE safety measures for electronic devices and, safety-wise, leave our factory in perfect condition. The devices comply with all currently
applicable EMC directives: Confirmed by the attached CE marking.
To minimize the risk of electric shock,
•
the mains plug grounding pin must never be separated and under no circumstances should the plug be taped up.
•
the device must only be connected to a professionally tested shockproof socket.
•
the amplifier housing and loudspeaker enclosure must never be opened. It does not contain any components that can
be repaired by the user. In the case of a defect, please consult qualified service personnel and/or the Fohhn dealer.
Please also ensure that the local mains supply voltage matches the power supply voltage specified on the device.
Warning!
To minimize the risk of an electric shock or fire,
•
the device must not be subjected to moisture/wet conditions for a long period of time.
•
containers filled with liquid (e.g. beverage containers) must not be placed on the device.
•
ventilation slots must not be covered with objects (e.g. protective rain covers).
•
the device must not be subjected to excessive heat, sunshine, fire or similar.
•
no open sources of flame (e.g. pyrotechnics) must be placed on the device.
To avoid damaging the device, do not leave the power cable plugged in if the device is not going to be used for a while.
Caution!
Remove the plug from the mains socket to completely disconnect the device.

5. Connections and wiring

Please note the following when wiring up your system:
•
Wiring of loudspeakers systems should only be carried out by suitably qualified personnel.
•
Only use cabling- and connector materials that meet professional standards and are working faultlessly.
•
Only use properly shielded plugs and cables with a sufficient cross section.
•
Only use power cables with a fully intact grounding pin.
•
Lay and secure the cabling in a way that it can't be damaged by tools, machinery, the loudspeakers or its accessories.
Warning!
•
Lay the cabling in such a way that it cannot be tripped over.
•
Protect any laid cables from unnecessary traction.
•
Never use any signal or power cables for mounting, hoisting or securing a system.
•
Note the respective pin assignment of audio and data cabling.
•
Avoid excessive tightening of the screws on connection terminals.

6. Operating conditions

The device should be immediately inspected by a Fohhn approved service partner if
•
the mains power socket is damaged,
•
a foreign body or liquid has got into the interior of the device,
Warning!
•
the device is not working normally i.e it is showing marked differences in performance,
•
the device is damaged (e.g. after a fall).
Please note the following when operating your Fohhn system:
•
The permitted ambient temperature of the device during operation ranges from 0 °C to +40 °C. A short period of use
outside this temperature range is possible, but not advisable.
•
The device is intended for use in a dry environment with normal levels of dust and humidity in the air.
•
Never expose the device to any aggressive chemical fluids or vapours.
Caution!
•
Always make sure that heat can be dissipated via the rear surface of the device enclosure. Maintain these gaps:
left/right side >5 cm, back >10 cm, top >10 cm.
•
Always make sure that the device is well ventilated. To ensure adequate cooling, the device must not be covered with
towels or cloths. Avoid letting the enclosure become hot through exposure to sunlight or strong spotlights.
•
Never expose the device to strong vibration.
Information on abnormal operation: If the permissible operating temperature of a powered Fohhn device (active speaker system or
amplifier) is too high (over 75 °C), the device will shut down automatically to protect itself. As soon as the temperature returns to within the
normal operating range, the device will automatically power up again. The temperature of the Fohhn system can be monitored in Fohhn Audio
Soft. Shutdown is getting more likely if the product is exposed to direct sunlight or very high environmental temperatures.

7. Storage and transportation

Please note the following:
•
The device should only be transported in its dedicated transport case.
•
Store the device in a dry environment with a constant ambient temperature to avoid condensation.
•
The permitted ambient temperature range for storing the device is -10 °C to +70 °C.
•
Due to fluctuations in temperature during transportation and storage, condensation may start to build up on the surface of the
device. Before operating the device, examine its surface for any signs of moisture. If this is the case, allow the unpacked device to
acclimatise for two hours in the environmental temperature before using it.
