3.3 Conduit Knock-outs and Wire Routing
Knock-outs are provided for routing cables through conduit or wire glands. Table 3-1 details the
knock-out sizes and quantity provided on the TriStar MPPT 600V wiring box. Knockout place-
ment dimensions are on the inside front cover. Figures 3-2 to 3-5 show knock-out types.
The TriStar MPPT 600V wiring box provides continuous and separate paths for high voltage
(solar) and low voltage (battery & COM) wiring routing. These allow wiring to pass between
TriStar MPPT 600V controllers that are mounted side-by-side without the need for external con-
duit tubing. Table 3-1 identifies the pass-through knock-outs which may be used for this purpose.
Figure 3-6 shows the routing of the high voltage and low voltage wiring paths.
