The FB107 accepts input voltages from 8.0 volts to 30 volts at the PWR
(IN+ / IN

) terminals on the CPU. The CPU terminal block accepts wires
from size 16 to 24 AWG.
The AUX PWR IN terminal block accepts wires from size 12 to 22
AWG.
2.1.5 Grounding Installation Requirements
Grounding wiring requirements for dc voltage sources equipment are
governed by the National Electrical Code (NEC). When the equipment
uses dc voltage sources, the grounding system must terminate at the service
disconnect. All equipment grounding conductors must provide an
uninterrupted electrical path to the service disconnect.

The National Electrical Code Article 250-83 (1993), paragraph c,
defines the material and installation requirements for grounding
electrodes.

The National Electrical Code Article 250-91 (1993), paragraph a,
defines the material requirements for grounding electrode conductors.

The National Electrical Code Article 250-92 (1993), paragraph a,
provides installation requirements for grounding electrode conductors.

The National Electrical Code Article 250-95 (1993) defines the size
requirements for equipment grounding conductors.
Proper grounding of the FB107 helps to reduce the effects of electrical
noise on the unit’s operation and protects against lightning. The FB107
provides lightning protection for built-in field wiring inputs and outputs.
Install a surge protection device at the service disconnect on dc voltage
source systems to protect against lightning and power surges for the
installed equipment.
All earth grounds must have an earth-to-ground rod or grid impedance of 25
ohms or less as measured with a ground system tester. The grounding
