PROTECTION FROM ELECTRIC SHOCK
• Do not expose the DMX PowerPort 375 to rain or moisture.
• Connect the DMX PowerPort 375 to AC mains power at 100-240 V (nominal), 50/60 Hz only.
• Ensure that the DMX PowerPort 375 is electrically connected to ground (earth).
• Use only a source of AC mains power that complies with local building and electrical codes and has both
overload and ground-fault (earth-fault) protection.
• The DMX PowerPort 375 can supply maximum DC current as follows:
- DMX PowerPort 375 can supply a safe maximum current of 5.0 A at its power and data output when
powered from 100-120 V mains. Do not connect devices that draw a combined total current of more
than 5.0 A to the DC power and data output when operating on this AC mains voltage range.
- The DMX PowerPort 375 can supply a safe maximum current of 7.5 A at its power and data output
when powered from 173-240 V mains. Do not connect devices that draw a combined total current of
more than 7.5 A to the DC power and data output when operating on this AC mains voltage range.
• The voltage and frequency at the mains power THRU connector are the same as those applied to the
mains power IN connector.
• If you connect DMX PowerPort 375 units to power in a daisy-chain by using 12 AWG / 2.5 mm
2
cable to
connect one unit’s mains power THRU connector to the next unit’s mains power IN connector, you can
link:
- a maximum of three (3) DMX PowerPort 375 units total in one chain at 100-120 V, or
- a maximum of six (6) DMX PowerPort 375 units total in one chain at 173-240 V.
• Check and respect the directions given in the user manuals of all the devices that you intend to connect to
the DMX PowerPort 375, particularly the instructions, warnings and limits that apply to:
- system layout,
- connections to other devices,
- specified cables,
- maximum cable lengths, and
- maximum number of devices that can be connected.
• The DMX PowerPort 375 unit does not have an ON/OFF switch. Make sure that the installation can be
isolated from power quickly and easily if there is an urgent need to shut down power to the unit.
• Provide a means of locking out AC mains power that allows power to the installation to be shut down and
made impossible to reapply, even accidentally, during work on the installation.
• Shut down power to the installation during service and when it is not in use.
• Double-pole/neutral fusing is used. If the installation is not completely disconnected from power, parts
may remain live even if one of the two mains fuses has blown.
• Use only a power input cable that has 12 AWG or 2.5 mm² minimum conductor size and an outer cable
diameter of 8 - 13 mm (0.35 - 0.5 in.). Power cable must be hard usage type (SJT or equivalent) and
heat-resistant to 90° C (194° F) minimum. In the EU the cable must be HAR type.
• Use only the cables specified by Martin for the devices concerned to interconnect them. If the specified
cables are not long enough for an intended cable run, consult Martin for assistance in finding or creating a
safe alternative cable.
• Before applying power to the installation, check that all power distribution equipment and cables are in
perfect condition and rated for the current requirements of all connected devices.
• Isolate the installation from power immediately if the product, power cable or power plug are in any way
damaged or defective, or if they show signs of overheating.
