2.3 Wiring
The AX-PENN (/ST7) peripheral expansion network node module is designed to be easy to install and wire. Pluggable
terminal blocks are provided for all wiring which can accommodate up to 14 AWG wire. Confirm wiring sizes are
adequate to deliver the required load current and maintain compatibility with the device voltages.
Note: Disconnect all sources of power (AC and battery) before installing components or servicing the module.
All wiring must comply with local, state and authority having jurisdiction requirements, in addition to Article
760 of the National Electrical Code (NEC).
