Fixture Set Up

1)

Read these safety instructions carefully to ensure OHM and accessories are used safely.

2)

Ensure the 28mm Spigot or 12mm Lifting Eye is correctly mounted onto the yoke before rigging.

3)

For an alternative method of hanging OHM, a Hanger Assembly is available as an accessory. Ensure this is 
correctly attached to OHM before rigging.

4)

Always use a suitable length safety cable(s) when hanging OHM. (Safety cables are not provided.) The length 
should be as short as possible to reduce travel distance if the primary hanging accessory fails.

5)

OHM weighs 32kg, excluding accessories. The combined weight should be considered when choosing a suitable 
safety cable(s).

page 9

).

7)

Ensure that the yoke locking handle is correctly tightened when manipulating OHM in the required orientation for 
safety purposes. NOTE: if the locking handle is not tightened correctly, the fixture may swing.

8)

Ensure the connection cables and any other cables are attached to the designated slots located on the yoke 
corners (detailed on 

page 8

).

9)

It is the user's responsibility to provide and wire their own power cable using the Neutrik power cable connector 
provided with OHM.

10) Ensure OHM is stored within the range of -20 to +60°C (-4 to 140°F).

Ventilation
