6. Installation
Choose a suitable mounting spot. Place the device on a level, flat surface. Do not hang the device.
Securing the flight-case cover
To make sure the cover does not close accidentally, you can secure it with the rivet, as follows.
1. With the cover open, lift the bracket upwards.
2. Keep the bracket in front of the hole at the inside of the flight case
and insert the rivet. The cover will now remain open.
Mounting the device
 Have the device installed by a qualified person, respecting EN 60598-2-17 and all other applicable norms.
 The carrying construction must be able to support 10 times the weight of the device for 1 hour without
deforming.
 The installation must always be secured with a secondary attachment e.g. a safety cable.
 Never stand directly below the device when it is being mounted, removed or serviced. Have a qualified
technician check the device once a year and once before you bring it into service.
 Install the device in a location with few passers-by that is inaccessible to unauthorised persons.
 Overhead mounting requires extensive experience: calculating workload limits, determining the installation
material to be used… Have the material and the device itself checked regularly. Do not attempt to install
the device yourself if you lack these qualifications as improper installation may result in injuries.
 Make sure there is no flammable material within a 0.5 m radius of the device.
 Have a qualified electrician carry out the electric connection.
 Connect the device to the mains with the power plug. All devices must be powered directly off a grounded
switched circuit and cannot be run off a rheostat or dimmer circuit, even if the rheostat or dimmer channel
is used solely for 0 % to 100 % switching.
 The installation has to be approved by an expert before the device is taken into service.
DMX-512 Connection
 When applicable, connect an XLR cable to the female XLR output of a controller (not incl.) and the other
side to the male XLR input [15] of the LX501. Multiple LX501s can be linked through serial linking. The
linking cable should be a dual core, screened cable with XLR input and output connectors.
 Maximum recommended serial data link distance is 500 meters (1640 ft). Maximum recommended number
of devices on a serial data link is 32 devices.
 A DMX terminator is recommended for installations where the DMX cable has to run a long distance or is in
an electrically noisy environment (e.g. discos). The terminator prevents corruption of the digital control
signal by electrical noise. The DMX terminator is simply an XLR plug with a 120 Ω resistor between pins 2
and 3, which is then plugged into the XLR output socket [16] of the last device in the chain.
7. Operation
The device does not feature an automatic stop function when running out of fluid; the
pump will continue working. Always monitor the reservoir fluid level during operation as
the device can suffer permanent damage when running without fluid.
