AC power
Warning! Read “Safety Information” on page 5 before installing the fixture. Lock
out power to the entire installation before working on cables and connections.
Electrical installation must be carried out by qualified professionals only.
For protection from dangerous electric shock, the fixture must be grounded (earthed).
The AC power distribution system must be fitted with current overload and ground-fault
(earth-fault) circuit breakers as well as a means to isolate fixtures from power and lock
out power during service.
The Exterior Projection 500 is supplied in EU and US models. Both models accept AC power at
100-240 V nominal or 277 V nominal at 50 or 60 Hz. Do not connect to power at any other voltage
or frequency.
You can connect the Exterior Projection 500 to either of the following mains power distribution
systems:
● Single-phase (live, neutral, ground/earth) system.
● Grounded/earthed three-phase four-wire (three phases, neutral, ground/earth) system.
Do not try to connect to a three-phase three-wire (three phases, ground/earth) system.
There is no power on/off switch. Power is applied to an Exterior Projection 500 fixture as soon as it
is connected to power. Provide a means to disconnect or shut down power to fixtures that is easily
accessible and is located close to the fixtures.
Do not use an external dimming system to supply power to the fixture, as this may cause damage
to the fixture that is not covered by the product warranty.
Protecting connections from moisture
Moisture can cause corrosion in unprotected cable connections. Moisture can also be sucked
along the inside of cables at breaks or cuts in the cable jacket (for example at connection points)
and into fixtures because of the vacuum effect of temperature fluctuations inside fixtures. To
protect connections and fixtures from moisture, take at least one of the following precautions:
● Locate cable junctions in dry areas (e.g. junction boxes in dry locations).
● Use connectors or junction boxes that are protected to IP67 or higher.
● Fill junction boxes with potting compound to seal the ends of cables and to protect connections
from corrosion.
Connecting to power
The fixture is supplied with a power cable installed ready for connection. See illustration below:

To connect to a single-phase system or to one phase of a three-phase four-wire system:
1. Lock out power to the installation.
