For enclosed panel installations, we recommend routing the heatsink portion through the back of the panel (external mounting) to preserve the interior thermal budget of the control cabinet.\u003c\/p\u003e\n\n\u003ch3\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eTo eliminate electromagnetic interference (EMI) on the \u003cstrong\u003eRS-485\u003c\/strong\u003e communication bus, always utilize shielded twisted-pair (STP) cabling. Connect the shield braid strictly to the physical ground terminal at the drive end only. Avoid routing control circuit wiring in the same conduit or parallel cable tray as the main R\/L1-S\/L2-T\/L3 input lines.
