Connecting To Power And Data - Martin Pro Compact Sicherheits- Und Installationshandbuch

Connecting to power and data

The Exterior Projection Pro Compact accepts AC mains 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 Pro Compact to either of the following mains power
distribution systems:
• Single-phase three-wire (Live, Neutral, Ground/Earth) system.
• Three-phase four-wire system with each fixture using one phase only.
Do not try to connect the fixture to a three-phase, three-wire (three phases, no Neutral) system.
There is no power on/off switch. Power is applied to an Exterior Projection Pro Compact 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.
Using power and data terminals
See photo on right. The Exterior Projection Pro Compact has
two-piece terminal blocks inside the fixture for making
connections to power and data. The terminal blocks have two
parts: a terminal base and a detachable terminal block.
• The terminal base stays inside the fixture.
• The detachable terminal block can be unscrewed and
removed from the base for convenient access when
connecting wires. When you have connected wires, you re-
insert the detachable terminal block back its base and fasten
it in place with its two screws. The detachable terminal block
can only be plugged into its base in one orientation (poka
yoke design).
The terminals are spring-loaded, automatic gripping type.
To fasten wires into terminals:
1. Strip approximately 50 mm (2 inches) of outer jacket from the power or data cable to free the wires
inside the cable.
2. Strip approximately 12 mm (half an inch) of
insulation from each wire, then crimp an insulated
ferrule onto the end of each wire. See photos on
right. The ferrules must be long enough to pass fully
into the terminals but no exposed metal must be
visible outside the terminals.
3. Push the ferrule on each wire firmly into the correct
terminal in the detachable part of the terminal block
following the instructions in this chapter. Pull on the wire to check that the ferrule is held securely
in the terminal. If you need to remove a wire from a terminal, insert a small electrician's
screwdriver into the hole on the front of the terminal and push on the spring inside the terminal to
release the wire.
The power terminal block has two sets of three terminals. Use one set of terminals for power IN and
one set of terminals for power THRU. It does not matter which set you use for power IN and which for
power THRU.
