2.6 Cabinet Wiring Examples
The terminal block and pin connections are illustrated in Figure 1.1. Power-limited (Class 2) wiring
must remain separated from nonpower-limited wiring by at least 0.25 in. (6.4 mm), and must enter
an enclosure through different knockouts. TB1 (Main 24V) and TB3 (AUX 24) on the AMPS-K2
board are power-limited (Class 2) when set for 3A maximum current in the programmed database.
Install tie wraps and adhesive squares to secure the wiring. Figures 2.6 through 2.9 show samples
of power-limited (Class 2) and nonpower-limited wiring configurations in different cabinets.
