Protection from injury
Fasten the fixture securely to a fixed surface or structure when in use. The fixture is not
portable when installed.
Ensure that any supporting structure and/or hardware used can hold at least 10 times the
weight of all the devices they support.
If suspending from a rigging structure, fasten the fixture to a rigging clamp. Do not use
safety cables as the primary means of support. If the fixture is installed in a location where
it may cause injury or damage if it falls, provide a secondary attachment such as a safety
cable inserted through the secondary attachment point that will hold the fixture if a primary
attachment fails. The secondary attachment must be approved by an official body such as
TÜV as a safety attachment for the weight that it secures, must comply with EN 60598-2-
17 Section 17.6.6 and must be capable of bearing a static suspended load that is ten times
the weight of the fixture and all installed accessories.
The safety and suitability of lifting equipment, installation location, anchoring method,
mounting hardware and electrical installation are the responsibility of the installer.
Block access below the work area and work from a stable platform whenever installing,
setting, adjusting, or cleaning the fixture.
After installation or service, check that the fixture and any optical accessories such as a
snoot or diffuser lens are securely fastened.
Do not operate the fixture with missing or damaged covers, shields or any optical
component.
In the event of an operating problem, stop using the fixture immediately and disconnect it
from power. Do not attempt to use a fixture that is obviously damaged.
