The DMX PowerPort 375’s Neutrik powerCON TRUE1 connectors support hot-plugging, so the DMX
PowerPort 375 does not have an ON/OFF switch.

Power connectors

Before inserting a TRUE1 connector into its receptacle (socket), line up keys and keyways carefully. If the
connector feels too stiff in the receptacle, remove it and check that the keyways are mating correctly.
Excessive stiffness is a sign that the connector is incorrectly lined up. Do not force it, or you may create a
serious safety hazard.

Power input

The DMX PowerPort 375 requires a power input cable with a Neutrik powerCON TRUE1 NAC3FX-W female
cable connector for AC mains power input. The cable must meet the requirements listed under “Protection
from electric shock” on page 5. Martin can supply suitable cables with female TRUE1 input connectors

1.5 m (4.9 ft.) or 5 m (16.4 ft.) long. Alternatively, Martin can supply loose female TRUE1 input connectors

(see “Accessories” on page 34).

If you need to install a Neutrik powerCON TRUE1 connector on a power cable, follow the instructions
available on the Neutrik website at www.neutrik.com.

The DMX PowerPort 375 can supply a safe maximum current of 5.0 A at its power and data output when it
is supplied with AC mains power at 100-120 V. Do not connect devices that draw a combined total current of
more than 5.0 A to the power and data output when using AC mains power within this voltage range.

The DMX PowerPort 375 can supply a safe maximum current of 7.5 A at its power and data output when it
is supplied with AC mains power at 173-240 V. Do not connect devices that draw a combined total current of
more than 7.5 A to the power and data output when using AC mains power within this voltage range.

In regions with 120 V mains power, the DMX PowerPort 375 can be powered using a split-phase
configuration to obtain 208 V and allow more fixtures to be connected to the unit.

Connecting to an AC mains power source

The power cable can be hard-wired to a building installation circuit or fitted with a cord cap (mains plug) for
connection to local power outlets.

If you install a cord cap (mains plug) on the power cable, install a grounding-type (earthed) plug, following

version remotely. When sending an ‘RDM Identify’ command to the DMX PowerPort 375, it will set its Data
LED to a flashing white pattern and set all connected fixtures to display a constant white pattern (as if the
Control button on the unit itself was pressed).

This transparent behavior allows Martin Creative LED Video fixtures connected to the DMX PowerPort 375
to be addressed and configured remotely from a lighting desk using RDM. No manual configuration of the
DMX PowerPort 375 or fixtures themselves is necessary.

Service and maintenance

Warning! Read “Safety Information” on page 4 before servicing the DMX PowerPort 375.

Warning! Disconnect the DMX PowerPort 375 from AC mains power before servicing.

Warning! Refer any service operation not described in this manual to a qualified service
technician.

Important! Excessive dirt buildup causes overheating and will damage the product. Damage caused
by inadequate cleaning is not covered by the product warranty.

Attention ! Lisez la section "Précautions d'emploi" en page 4 avant de démarrer l'entretien du DMX
PowerPort 375.

Attention ! Déconnectez le DMX PowerPort 375 du secteur avant de commencer l'entretien.

Attention ! Référez toute opération non décrite dans ce manuel à un service technique qualifié.

Important ! Un encrassement excessif peut causer des surchauffes et endommager le produit. Les
dommages causés un nettoyage inadéquat ne sont pas couverts par la garantie du produit.

The user will need to clean the DMX PowerPort 375 periodically, and may replace fuses in the fuseholders
on the rear panel if necessary. All other service operations on the DMX PowerPort 375 must be carried out
by Martin Professional or its approved service agents.

Installation, on-site service and maintenance can be provided worldwide by the Martin Professional Global
Service organization and its approved agents, giving owners access to Martin’s expertise and product
knowledge in a partnership that will ensure the highest level of performance throughout the product’s
lifetime. Please contact your Martin supplier for details.

Fuse replacement

Warning! Replace fuses with fuses of the same type and rating only.

Attention ! Remplacez uniquement les fusibles fondus par des fusibles de même type et de même
valeur.

The DMX PowerPort 375 is protected by two 6.3 amp slow-blow fuses located in fuseholders on the rear
panel (see Figure 1 on page 8). One fuse protects the Live line and one protects the Neutral line – this setup
is necessary to ensure full protection when using a split-phase configuration on 120 V networks to obtain
208 V. If either fuse blows, the DMX PowerPort 375 and all fixtures connected to it will stop working.

If the unit stops working although it is connected to power, the overload protection may have been activated
or a fuse may have blown. If you suspect that a fuse has blown, replace the fuses as follows:

1. Disconnect the DMX PowerPort 375 from power.

2. Using a screwdriver, turn each fuseholder cap counter-clockwise to release it, then remove each fuse.

3. Replace defective fuses with fuses of the same type and rating.

4. Reinstall both fuseholder caps before reapplying power.

Cleaning

Cleaning schedules vary greatly depending on the operating environment. It is therefore impossible to
specify precise cleaning intervals for the DMX PowerPort 375. Cooling fans suck in airborne dust and smoke
particles, and in extreme cases, the product and its air filters may require cleaning after surprisingly few
hours of operation. Environmental factors that may result in a need for frequent cleaning include:

• Use of smoke or fog machines.

• High airflow rates (near air conditioning vents, for example).

• Presence of cigarette smoke.

• Airborne dust (from stage effects, building structures and fittings or the natural environment in outdoor

locations, for example).

14

DMX PowerPort 375™ User Manual

If one or more of these factors is present, inspect units within their first 25 hours of operation to see whether
cleaning is necessary. Check again at frequent intervals. This procedure will allow you to assess cleaning
requirements in your particular situation. If in doubt, consult your Martin™ dealer about a suitable
maintenance schedule.

Warning! Disconnect from power and allow to cool for 10 minutes before cleaning.

Warning! Do not allow the unit to become wet. Wipe with a damp cloth only.

Attention ! Déconnectez le produit et laissez-le refroidir pendant 10 minutes avant de procéder au
nettoyage.

Attention ! Ne laissez pas le produit se couvrir d'humidité. Nettoyez-le avec un chiffon légèrement
humide.

To clean the DMX PowerPort 375:

1. Disconnect the unit from power.

2. Use a vacuum cleaner and soft brush to gently remove dust and loose particles from the outside of the
unit, paying special attention to the air vents in the front panel.

3. Wipe the outside of the unit with a cloth lightly moistened in a mild detergent solution. Do not splash the
unit with water. Do not use any product that contains abrasives or solvents.

4. Check that the unit is dry before reapplying power.

Installing new software

It may be necessary to upload new software (i.e. device firmware) to the DMX PowerPort 375 if it appears to
have a software-related fault or if you want to update to a newer software version.

To upload new software:

1. Connect a PC running the Martin Companion WIndows application (available from the Martin website at
www.martin.com) to the Internet. Allow the application to automatically download all the latest Martin
product firmware to your PC.

2. Shut down power to the DMX PowerPort 375.

3. Connect the PC running Martin Companion to the DMX PowerPort 375’s DMX IN connector using the
Martin Companion Cable USB-DMX hardware interface available from Martin (see “Related Items” on
page 19).

4. Apply power to the DMX PowerPort 375 and follow the instructions in the Martin Companion application.
