Warning! Read "Safety Information" on page 3 before attempting to
install this product. Lock out power to the entire installation before
working on cables and connections or removing any cover.
Electrical installation must be carried out by qualified professionals
For protection from dangerous electric shock, the fixture must be
grounded (earthed). The AC mains power distribution system must
be fitted with both 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.
Important! Do not connect the Extube to an electrical dimmer
system. Doing so can damage the electronics.
If you require help in planning or dimensioning the power distribution
system, please contact your Martin supplier for assistance.
If there is a break or cut at any point in a cable (for example at a
connection point), and if this is exposed to water, moisture can be drawn
up the inside of the cable due to the vacuum effect of temperature
fluctuations during operation. Ensure that the fixture is protected from the
entry of water via the power cable by using IP65-rated connectors or
junction boxes, or by protecting connectors with weatherproof housings.
The Extube does not have a power on/off switch. Power is applied to the
fixture as soon as it is connected to power.
AC mains power voltage and frequency
The Extube accepts AC power at 100 - 120 and 200 - 240 V nominal, at
50 or 60 Hz. Do not connect the fixture to power at any other voltage or
Current and fuse ratings
See "Typical Power and Current" on page 36 for details of current drawn
by Extube fixtures.
Extube 300 mm fixtures are protected by a 1 amp slow-blow primary fuse
and 1200 mm fixtures are protected by four 1 amp slow-blow fuses. Fuses
are located internally on the power PCB and are not user-serviceable. If
you suspect that a fuse has blown, please contact your Martin supplier for
