The NGC is designed for connection to a 12VDC or 24 VDC power source. The 12

volt power source must provide a minimum of 10.5VDC to a maximum of 16VDC

at 4 amps minimum, and the 24 volt must provide a minimum of 21VDC to a

maximum of 28VDC at 2.2 amps. The configurations with the auxiliary feedthrough heater increase the requirements.

Adequate wire size is a function of the distance between the NGC and the DC

power supply. When running wiring from the power source to the NGC,

consideration must be given to the voltage dropped between the power source

and the NGC. Smaller wire gauges have greater resistance and, therefore, a

greater voltage drop across the wiring. The following tables (see Table 1–4 and

Table 1–5) document multiple cable sizes and corresponding maximum cable

lengths for DC and AC installations with and without the auxiliary feed-through

assembly heater.

Additional devices connected to the NGC and requiring power (XMVs, radios, etc.)

must be factored into this calculation. Refer to their technical specifications for the

requirements of each, or call Totalflow for help computing cable requirements for

additional loads.
