Siemens also does not recommend using copper Ethernet ports to interface with devices in the field across distances that could produce high levels of ground potential rise (i.e. greater than 2500 V), during line-to-ground fault conditions.
This product contains no user-serviceable parts. Attempted service by unauthorized personnel shall render all warranties null and void. Changes or modifications not expressly approved by Siemens Canada Ltd could invalidate specifications, test results, and agency approvals, and void the user's authority to operate the equipment.
Section 2.3 Installing the Device in Hazardous Locations The RUGGEDCOM RS920W is designed to comply with the safety standards for Class I, Division 2 hazardous locations where concentrations of flammable gases, vapors or liquids may be present, as opposed to normal operating environments.
Section 2.4 Mounting the Device The RUGGEDCOM RS920W is designed for maximum mounting and display flexibility. It can be equipped with adapters that allow it to be installed on a 35 mm (1.4 in) DIN rail or affixed to a panel.
Section 2.4.2 Mounting the Device to a Panel For panel installations, the RUGGEDCOM RS920W can be equipped with panel adapters on the top and bottom of the chassis. The adapters allow the device to be attached to a panel using screws.
Control of the failsafe relay output is configurable through ROS. One common application for this relay is to signal an alarm if a power failure occurs. For more information, refer to the ROS User Guide for the RUGGEDCOM RS920W. To connect the failsafe alarm relay, do the following: Insert the failsafe alarm relay terminal block into the device and tighten the screws.
