POWER AND CONTROL CABLING
AL Graze AC fixtures use proprietary connectors (mains plus DMX)
for their inputs and outputs. The connector placements at each end
of every fixture are such that abutted
fixtures can be directly connected
without need for extra link
cables.
The contacts of
the required
feed-in cable
(available as a
separate item)
are arranged as
shown here:
IN-RUSH CURRENTS
Although LED fixtures are low power devices compared to their traditional source
equivalents, their power supplies exhibit a trait known as ‘in-rush’ when they are first
powered on. This is caused by the various components within the switched mode
power supplies initially topping themselves up with power. The in-rush period lasts only
milliseconds and does not cause any effect when a handful of units are powered on at the
exact same time. However, if many fixtures are linked to the same power input, they will
momentarily pull a current that may greatly exceed their normal operating level. This may
affect over-current trips when power is applied and should be anticipated when planning
the power panel size requirements.
INTERCONNECTING
Each AL Graze AC fixture has a short cabled power input plug at one end and an integral
power/signal output socket at the other. When fixtures are daisy chained (and are directly
abutted), the input plug of one fixture can connect directly to the output socket of the
previous fixture. Alternatively, where fixtures are not abutted, one of the optional link cables
can be used to make up the gap between any two fixtures.
Ensure the output connector of the final fixture has an end cap fitted [AGHEC]. This will
correctly terminate the DMX link and also prevent moisture ingress.
Note: Ensure that the mains power is supplied from a suitably protected source and initial
connections are made within IP rated enclosures.
