AC power
DANGER! Read “Safety Information” on page 3 before attempting to install an Exterior 400 Range
fixture. 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 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.
Important! Do not connect an Exterior 400 Range fixture to an electrical dimmer system. Doing so
can damage the electronics.
See Figure 7 on page 11 for a schematic diagram of cable layout. If you require help in planning or
dimensioning the power distribution system, please contact your Martin Architectural 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 Exterior 400 Range is supplied in EU and US models. Both models accept AC power at 100 - 240 V
nominal, 50 or 60 Hz. Do not connect to power at any other voltage or frequency.
The Exterior 400 Range is protected by a 2.5 amp slow-blow primary fuse located on the power PCB inside
the rear cover. See “Fuse replacement” on page 28 for details of changing fuses.
There is no power on/off switch. Power is applied to an Exterior 400 Range fixture as soon as it is connected
to power. Provide a means to disconnect from power or shut down power to fixtures that is easily accessible
and is located close to the fixtures.
Connecting to power
The fixture is supplied with a power cable installed ready for connection to a single-phase 3-wire (live,
neutral, ground/earth) power distribution system at 100 - 240 V nominal, 50/60 Hz.
Important! If you have any other type of distribution system than the one listed above, you must replace the
power cable and connect the fixture to power as described under “Replacing the power cable” on
page 13.
To connect to a single-phase 3-wire (live, neutral, ground/earth) power system:
1. Lock out power to the installation.
2. The power cable color coding for US and EU models is given in Table 1. Connect the conductors in the
power cable to the distribution circuit as follows:
- Connect the green wire (US models) or yellow/green wire (EU models) to ground (earth)
- Connect the white wire (US models) or blue wire (EU models) to neutral
- Connect the black wire (US models) or brown wire (EU models) to live.
