5.4 AC Mains Power Connection
This section details the requirements for the ac mains which is the ac
power connection required by each DSAi module.
5.4.1 AC MAINS SUPPLY
WARNING: Read WARNING under SAFETY INSTRUCTIONS on Page 2.
Each DSAi Series module is rated for a particular nominal ac mains
voltage: 115 V or 230 V. Provide the module with 50 Hz or 60 Hz ac
mains circuit capable of:
100 V to 120 V 220 V to 240 V
DSA230i and DSA250i 4 A 4 A
Before applying power, ensure that the ac mains voltage matches the
voltage rating on the module.
DANGER: DO NOT APPLY 230 V MAINS POWER IF THE VOLTAGE
RATING ON THE MODULE IS 115 V. IMMEDIATE AND CATASTROPHIC
DAMAGE TO THE MODULE WILL RESULT AND MAY CAUSE A FIRE
HAZARD, SERIOUS PERSONAL INJURY, OR DEATH.
5.4.2 AC MAINS CABLE
The supplied Neutrik PowerCon NAC3FCA plug mates with the Neutrik
PowerCon NAC3MPA AC MAINS jack on the module. Because of both
varying installation and electrical code requirements, neither an ac
mains cable nor ac mains supply connection are supplied.
1. Supply and connect a 3-conductor power cable to the supplied
PowerCon plug, ensuring a proper ground connection.
2. Supply and attach an appropriate connector for the ac mains
connection at the other end.
Recommended Power Cable
Conductor Gauge: 14 AWG / 2.5 mm (limited by PowerCon design)
Cable O.D.: 5 mm to 15 mm (limited by PowerCon design)
Recommended length: Maximum 25 ft / 8 m (for <2% voltage drop at
peak input power)
NOTE: If the power cable is longer than 25 ft / 8 m the voltage drop will
increase.
5.4.3 POWER ON / OFF
There is NO power on/off switch on DSAi Series modules. A module will
be powered on (energized) when connected to an ac mains supply. For
about 3 seconds when first powered on, the LED on the Signal End will
flash rapidly and the FAULT DETECT relay in the Power End cap will
click on and off. This is normal and indicates the electronics are being
initialized. The LED should then go off. See Section 6.1.2 for other LED
indications.
