10 Fusion MBL20 User Manual Rev. A
2. Avoiding damage to the fixture
Important! Follow the directions in this section carefully, or the fixture may suffer damage
that is not covered by the product warranty.
General precautions
Do not drop the fixture or expose it to mechanical stress.
Protect the onboard LCD display and control panel from shocks, or they may suffer
damage that is not covered by the product warranty.
Do not expose the fixture to heat (from other lighting fixtures for example).
Clean optical components only as directed. Oils, solvents, and other chemicals commonly
used for cleaning can damage the lens coatings and surfaces.
Use only original spare parts. Do not make any structural modifications to the fixture or you
will void the product warranty.
Avoiding damage from light sources and heat
To avoid problems from strong light sources:
● Do not expose the front of the fixture to sunlight or any other strong light source.
● In outdoor applications during daylight, make sure that the front face of the fixture is
shielded or points away from the sun, even when not in use.
● Do not aim other high-powered beam lights directly at the fixture.
Do not operate the fixture in ambient temperatures above 40° C / 104° F. Allow free airflow
around the fixture.
IP rating
MBL20 fixtures are IP65-rated:
● IP stands for Ingress (entry into the fixture) Protection.
● The first figure 6in the rating means that fixtures are protected against the entry of dust
and airborne particles.
● The second figure 5 in the rating means that fixtures are protected against the entry of
rain and water projections from all angles. Fixtures are not protected against immersion
in water and they are not protected against high-pressure water jets.
Avoiding damage from water and humidity
● Do not install MBL20 fixtures in a location where water can pool around the fixture or
allow MBL20 fixtures to become submerged in any other way. Do not aim low- or high-
pressure water jets at fixtures.
● Keep all unused connectors on the fixture sealed with their protective caps, both when
the fixture is being used and when it is not in use.
● In outdoor and high-humidity environments, use IP65-rated power and data connectors
and cable (an IP65 rating means that the item is protected against the entry of water
from rain, projections and low-pressure jets as well as the entry of dust). When assembling
connectors and installing them on cable, follow the manufacturer’s instructions (see

German Light Products® Avoiding damage to the fixture
Fusion MBL20 User Manual Rev. A 11
www.neutrik.com) and ensure that an IP65 rating is maintained for the complete
assembly. Use only the following cable connectors:
- IP65-rated 5-pin XLR connectors for data IN and OUT (THRU)
- Neutrik powerCON TRUE1 NAC3FX-W for Power IN
- Neutrik powerCON TRUE1 NAC3MX-W for Power OUT (THRU).
● Apply a dielectric grease (available from electrical suppliers) to connector terminals and
caps to prevent corrosion and/or electrical short circuits.
● Make sure that cables open into dry areas or sealed junction boxes. Moisture can be
drawn along cables by capillary action or pressure variations resulting from thermal
expansion.
● See drawing on right.
Arrange cables so that they
arrive at connectors from
below. Make sure that it is
impossible for water to flow
down cables and
accumulate at connectors.
If necessary, provide extra
cable slack and create ‘drip loops’ before connectors.
● Create loose cable bends only. Do not subject connections to bending forces or allow
connections to bear the weight of long lengths of cable.
Avoiding damage from dust and airborne particles
● Carry out regular visual inspections of the fixture to make sure that there is no
accumulation of dirt, especially on the front of the fixture.
● If cleaning is necessary, follow the instructions in ‘Service’ on page 33.
Transportation and storage
● If fixtures have been fastened together with locking pins, remove the pins and separate
the fixtures before transport. Do not transport fixtures that are fastened together, or
shocks during transport will expose fixtures to leverage forces and may cause damage
that is not covered by the product warranty.
● Transport the fixture in its original packaging to protect it from damage caused by
shocks during transportation.
● Store the fixture in a dry location when not in use.

4. Installation
Warning! Read ‘Safety’ starting on page 5 for important safety information that
you must understand before you install or operate the fixture. Install MBL20
fixtures only as described in this chapter, or you may create an installation that is
unsafe.
Install the fixture at least 0.2 m / 8 in. away from combustible materials (wood,
textiles, paper, etc.), 0.2 m / 8 in. away from any surface that will be illuminated,
and a safe distance away from any flammable materials (volatile spirits, etc.).
It is the installer’s responsibility to provide a stable, secure supporting structure
that is suitable for the environment and application and that meets all
applicable codes and legal requirements. Note the requirement to secure
lighting fixtures with safety cables in temporary installations.
Permitted mounting options
An MBL20 fixture may be installed in one of the following ways:
1. Fastened to a surface at any angle by screwing through the mounting bracket.
2. Fastened to a rigging truss or similar structure at any angle by means of a truss coupler
or other clamp fixed to the Omega bracket accessory which attaches to the two half-
turn couplers on the mounting bracket.
Securing fixtures with a safety cable
In temporary installations, if a fixture could cause injury or damage by falling you must
secure it with a secondary attachment such as a safety cable that will hold it if the primary
means of attachment fails. The safety cable must be approved for the weight that it
secures. In multiple installations, each fixture must have its own safety cable.

www.glp.de Installation
16 Fusion MBL20 User Manual Rev. A
To secure an MBL20 fixture with a safety cable:
Figure 2. Safety cable attachment point
1. Loop a safety cable around a secure anchoring point such as a truss or fixed structure
so that it will catch the fixture if a rigging clamp fails. Take up as much slack as possible
in the safety cable (by looping it more than once around the truss, for example).
2. See Figure 2. Fasten the safety cable to the attachment hole on the back of the fixture.
Check that the fixture is now secured.
Installing on a surface at any angle
To install an MBL20 fixture on a surface at any angle:
1. Check that the surface is secure and can safely hold the weight of the fixture plus all
hardware and cables.
2. Loosen the handwheels on the mounting bracket, adjust the bracket to a suitable angle
and tighten the handwheels.
3. Hold the fixture in position on the surface and mark the positions of holes for fasteners on
the surface. You will need at least two fasteners. Drill holes if necessary.
4. Fasten the mounting bracket to the surface by passing at least two suitable fasteners
such as grade 8.8 steel bolts or screws through the holes in the bracket and fastening
them to the surface. Fasteners must be suitable for their purpose and the installation
environment.
5. In a temporary installation, secure the fixture with a safety cable as described in
‘Securing fixtures with a safety cable’ on page 15 if there is any risk that the fixture will

www.glp.de AC mains power
18 Fusion MBL20 User Manual Rev. A
5. AC mains power
Warning! Read ‘Safety’ starting on page 5 for important safety information that
you must understand before you install or operate the fixture.
Check that all cables and connectors are suitable for the installation
environment and application (see recommendations in ‘Avoiding damage to
the fixture’ on page 10).
Use H07 RN-F 3 x 2.5mm / SJT 12 AWG cables with original Neutrik powerCON
TRUE1 connectors to supply power to fixtures.
Line up the keyways in connectors carefully. Do not try to insert or twist a
connector if it feels excessively stiff. Resistance to insertion or twisting is a sign
that connectors may be incorrectly lined up.
Keep connectors sealed with their rubber caps at all times when not in use.
Included items
The MBL20 is supplied with a power cord with Neutrik powerCON TRUE1 connector.
Connecting to power
The AC mains power supply must include a connection to ground / protective earth. It must
be protected against ground / earth leakage and overload. The fixture’s internal auto-
sensing power supply accepts AC power at 100-240 V, 50/60 Hz. Do not connect the fixture
to power at any other voltage or to an external dimmer.
The MBL20 does not have a power ON/OFF switch. Power is applied to the fixture as soon as
the power cable becomes live.
The MBL20 has a 3-conductor Neutrik powerCON TRUE1 Mains IN power input socket that
accepts AC power from a TRUE1 female cable connector. Although TRUE1 connectors
support hot plugging, it is still good practice to shut down power to power cables before
connecting them to fixtures.
To connect the fixture to power:
1. If convenient, shut down power to the power input cable.
2. Note the position of the keys and keyways on the TRUE1 power cable connector and
Mains IN socket and align them with each other. Insert the cable connector into the
socket and twist clockwise to lock. Do not use force. If the connector feels excessively
stiff, remove it and check again that it is lined up correctly.
3. Before applying power to the power cable, check that nobody is looking directly into
the front of the fixture.
To disconnect the fixture from power, pull the latch on the cable connector outwards to
release it, then twist the connector counterclockwise and pull to remove it from the socket.
Installing power connectors
If you intend to draw power from convenience receptacles / consumer mains power
sockets, it is possible to install a suitable cord cap / power plug on the supplied power cord
/ input cable. If you do this, check that the cord cap / plug is rated minimum 250 V, 16 A,

German Light Products® AC mains power
Fusion MBL20 User Manual Rev. A 19
that it has a connection to ground / earth and that it has an integral cable grip. Follow the
cord cap / plug manufacturer’s assembly instructions.
If you need to install a Neutrik powerCON TRUE1 connector on a power cable, follow the
instructions given in the Support area of the Neutrik website at www.neutrik.com.
Respect the color coding used in the supplied power cable and in your local mains power
wiring system. US and EU systems use the color coding shown below:
Live or L Neutral or N Ground / Earth or
US system Black White Green
EU system Brown Blue Yellow/green
Connecting multiple fixtures to power in a chain
You can connect fixtures to power in a daisy-chain to simplify your power circuit layout.
MBL20 fixtures have 2.5 mm2 internal wiring from Power IN to Power THRU connectors.
Warning! Do not connect more than six (6) MBL20 fixtures in total to power in one
chain at 100-120 V, 60 Hz. Do not connect more than twelve (12) MBL20 fixtures
in total to power in one chain at 200-240 V, 50 Hz.
The power input cable supplied with the fixture is rated 16 A maximum. Add
together the maximum current draw ratings of all the devices that you intend to
connect to power in a daisy chain and do not create a chain with a total
maximum current draw of more than 16 A, or you will create a risk of fire and
electric shock.
To connect fixtures to power in a chain:
1. Obtain power relay cables that have male and female Neutrik powerCON TRUE1
connectors. Cables must be minimum 14 AWG or 1.5mm2, rated minimum 16 A and
suitable for the environment and application.
2. Connect the power input cable to the Mains IN socket of the first fixture as described
under ‘Connecting to power’ on page 18.
3. Connect a relay cable to the Mains OUT / THRU socket of the first fixture and to the
Mains IN socket of the second fixture.
4. If you are using 100-120 V, 60 Hz AC mains power you can continue connecting MBL20
fixtures Mains OUT / THRU socket to Mains IN socket until the chain contains a maximum
of six (6) fixtures in total. If you are using 200-240 V, 50 Hz AC mains power you can
continue connecting fixtures Mains OUT to Mains IN until the chain contains a maximum
of twelve (12) fixtures total.
