G.6.10 J7 - Power Interface (DC)
The power supply sub-system is designed with the following assumptions about the input
power source:
• Input voltage: Nominal 24 V ±4 V
• Maximum power consumption: 24 W
• Maximum input noise: 1.0 Vp-p max at 50-120 Hz, 100 mVp-p max 120-300 kHz
• Low Voltage Directive Compliant (SELV)
• Panel power connector is a DB9-M. Power cord should have a female DB9 connector,
DB9-F
• Cable to power connector should use 18-gauge wire with power and ground twisted. If
the cable is not shielded a ferrite should be added as close to the connector as possible
with the cable looped through twice.
