1 SEL-3421 Motor Relay HMI (With LCD) Quick-Start Guide Overview The SEL-3421 Motor Relay HMI can: Read metering and monitoring data. Inspect targets. Control relay operations. Display diagnostics. Display, trigger, or clear events. The SEL-3421 has ten LEDs, eight of which are tricolor and programmable, with configurable labels. ENABLED and TRIP are the two fixed LEDs. This module has a graphical display with six pushbuttons for navigation, five soft keys for functions, and four pushbuttons for control. What s in the Box?

This manual uses three kinds of hazard statements, defined as follows: DANGER Indicates an imminently hazardous situation that, if not avoided, will result in death or serious injury. WARNING Indicates a potentially hazardous situation that, if not avoided, could result in death or serious injury. CAUTION Indicates a potentially hazardous situation that, if not avoided, may result in minor or moderate injury or equipment damage. WARNING To avoid the risk of electrostatic discharge when using the SEL-3421 HMI, take one of the following precautions: 1) touch the front panel with an insulated object, 2) use ESD shoe covers to insulate shoes from the ground before touching the front panel, or 3) step on an insulated mat before touching the front panel.

5 5 Gasket Installation for the SEL-3421 Panel Mount Step 1. Remove the inner rectangular section from the gasket. Step 2. Peel off the paper to expose the adhesive. Step 3. Position the gasket, with the adhesive side to the rear of the SEL-3421, so that the gasket is inside the outer edge of the plastic casing and the four screw holes are inside the inner rectangle of the gasket. Step 4. Press the gasket to the rear of the SEL-3421 to create a seal around the edge of the SEL Date Code SEL-3421 Motor Relay HMI

6 6 DIN Rail Mount Connection The RJ45 port on the rear of the SEL-3421 connects to the HMI port on the SEL-849 Relay and receives power from the HMI port. Connection to the relay requires an RJ45 Ethernet cable, such as the SEL-C627M, double-shielded, 600 V, MCC-rated, category 5e Ethernet cable, with a maximum length of 7.62 meters (25 feet). When the relay is turned on, the HMI displays the status of each LED, as shown in the product photo in Overview. Refer to Section 8: Human Machine Interface and Section 1: Introduction and Specifications, in the SEL-849 Instruction Manual for more details on the HMI operation and specifications. NOTE: Make sure the relay, HMI, and SELBOOT firmware revisions are compatible. Refer to Appendix A: Firmware and Manual Versions in the SEL-849 Instruction Manual. Accessories For customizing the LED labels on the SEL-3421/SEL-3422 modules, order Configurable Label Kit, P/N Order P/N for replacement screws, DIN rail clips, and DIN rail supports for as many as five SEL-3421/SEL-3422 HMIs. The SEL-3421 does not ship standard with an SEL-C627M Ethernet cable. To purchase an SEL-C627M cable, please visit SEL-3421 Motor Relay HMI Date Code
