safety wire attachment point

5.Working from a stable platform, hang the fixture on the truss. The front of the fixture is indicated by the arrow on the base.

6.Install a safety wire that can bear at least 10 times the weight of the fixture. The attachment point is designed to fit a caribiner clamp. Never use the carrying handles for secondary attach- ment.

7.Tighten the rigging clamps securely to the structure.

8.Verify that there are no combustible materials or surfaces to be illuminated within 1 meter of the fixture, and that there are no flammable materials nearby.

I M P O R T A N T !

When rigging the fixture within 1 meter of other fixtures, avoid illuminating

one fixture with another. The intense light can melt plastic parts.

1.Use shielded twisted-pair cable designed for RS-485 devices: standard microphone cable cannot transmit DMX data reliably over long runs. For links up to 300 meters (1000 ft.) long, you can use 24 AWG, low capacitance, 85-150 ohm characteristic impedance, shielded cable with 1 or more twisted pairs. For runs up to 500 meters (1640 ft.) use 22 AWG cable. Use an amplifier if the serial link exceeds 500 meters.

2.Never use a “Y” connector to split the link. To split the serial link into branches use a splitter such as the Martin 4-Channel Opto-Isolated RS-485 Splitter/Amplifier.

3.Do not overload the link. Up to 32 devices may be connected on a serial link.

4.Terminate the link by installing a termination plug in the output socket of the last fixture on the link. The termination plug, which is simply a male XLR connector with a 120 ohm, 0.25 watt resistor soldered between pins 2 and 3, “soaks up” the control signal so it does not reflect back down the link and cause interference. If a splitter is used, terminate each branch of the link.
