3.2 Installation Procedures (LES301A-KIT or LES301AE-KIT)

Step 1: Connect an LES301A to the included power supply (PS012 or PS012E) or to a 9–30 VDC source.

Step 2: Connect the LES301A to an Ethernet network. Use a standard straight-through Ethernet cable to connect to a hub/

switch, or connect it to a PC’s Ethernet port via a cross-over Ethernet cable.

NOTE: The PC must be in the same subnetwork as the LES301A.

Step 3: Connect the LES301A’s serial port to a serial device.

NOTE: You may need an adapter (LES30X-TB5) for RS-485 or RS-422 applications.

Step 4: Mount the LES301A to a wall or panel using the included mounting screws. Or, mount the unit to a DIN rail rack using

the DIN Rail Kit (LES30X-DR).

NOTES: Disconnect the device from power source completely before installing and wiring the server.

Do not exceed the maximum allowable current of the power cord and common wire. If you don’t, the wire might overheat

and cause serious damage to the connected and neighboring equipment.

The casing will be too hot to touch when operating in harsh environments. Please handle with care.

NOTE: Ground the LES301A properly through frame ground.
