Use an SEL Transceiver Mounting Kit and adapter cable when connecting the transceiver to IEDs with an RJ-45 male serial connector or when the mounting depth is an issue (e.g., in switchgear applications). The following kits provide a simple and secure way to remote-mount the transceiver away from the host connector:
