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).
