Please note that Neutrik Powercon connectors are not 'hot-swappable'. This means that the Powercon
connectors may not be pulled out of the chassis if the cable is still connected to a power output socket.
The ERO 704 is equipped with a fuse for its own components. The power input of the device is directly linked
to the power output of the device.
Please note that the internal 1.5mm² power wiring of the fixture wiring and the included cables are designed
to withstand a maximum current of 16 A. However, please pay attention to the maximum allowed power that
is available on the power outlet (and/or the electrical installation) you are going to use.
When using the daisy-chain option to link several fixtures through the input and output of the device (using
only the original, included cables), a maximum of 17 fixtures can be used. If you wish to power additional
fixtures, a new daisy-chain loop must be made on a new power outlet.
XLR input and output
The ERO 704 fixtures are equipped with XLR chassis connectors. The DMX input is usually connected with a
XLR cable that has a locking mechanism so it can not be pulled from the chassis easily. Usually the locking
part has to be pressed and held to unlock the mechanism. When doing this, the connector can be removed
from its socket.
Fan control
The ERO 704 is equipped with intelligent fan and temperature control. Through the display, it is possible to
read the actual temperature measured by the head and body by temperature sensors.
The default setting of the fans is automatic. This means that the fans are in temperature-controlled mode and
will not turn on unless the temperature rises to a certain level. The fans have 3 speeds, so when the fan is
activated after passing the first temperature level, it will only spin slightly without too much noise.
Through the menu, the user has access to the fan control settings. Please be aware that the automatic mode
is the best mode, as the fixture will regulate the fan speed properly.
The internal fans of the head and body (for the LEDs and power supply) can be turned off, should the
situation require it. If the temperature is high, which could occur if the fixture is used at full output for a
longer period of time, for instance, the fixture will try to reduce output power to lower the temperature. If this
does not work, the fixture will be shut down.
When using the fixture for theatrical applications, you may want to switch off the fans during quiet scenes, so
the theatre is absolutely silent and without fan noise.
If the fans are switched off and the temperature rises, the LED output power will be decreased should the
temperature level exceed 65 degrees Celsius. If the temperature rises any further, the output will be
progressively lowered to protect the LED and its connections from overheating and/or reducing the lifespan
of the device.
When using the fixture in fixed installations such as a club or bar, where loud music is typically present, it is
recommended to use the fan control's medium, high or auto mode, as the music will drown out any noise
from the fan. Often there is a large crowd present in night clubs and bars, and as such the temperature in the
venue rises easily. As hot air rises, the temperature level at the ceiling or roof (where fixtures are installed
usually) may be up to 10 degrees Celsius higher than the average temperature level in the room!
To ensure that the fixture remains reliable and the temperature control will not reduce the output power, use
proper fan settings so the fixtures will continue to perform without any problems. Please contact your local
dealer if you are not sure which settings to use for your purpose.
