Rice Lake CW-90X Over/Under/Washdown Checkweigher - Ethernet - Manual (Page 6)

2 Ethernet TCP/IP Card Installation Manual
2.0 Installation
Rice lake indicators have no on/off switch. Before opening the unit, ensure the power cord is
disconnected from the power outlet.
The Ethernet card should NOT be used to communicate between buildings. The Ethernet port is not
suitable for connection to circuits used outside the building and is subject to lightning or power
faults.
Use a wrist strap to ground yourself and protect components from electrostatic discharge (ESD)
when working inside the indicator enclosure.
This unit uses double pole/neutral fusing which could create an electric shock hazard. Procedures
requiring work inside the indicators must be performed by qualified service personnel only.
The indicator enclosure must be opened to install the Ethernet card.
