Hardware Installation (DIN-Rail Mount) (Optional Wall Mount) The switches with DIN-Rail bracket has a steel spring in the upper rail of the bracket. This spring is compressed for mounting and un-mounting by applying downward force. (Mounting) (Un-Mounting) 2-6.2 Wiring The Power Input A removable terminal block on the top panel provides both power and alarm connections.
Hardware Installation The two power connections are shown in the above graphic. The device has clearly printed on the case the locations of the two power inputs, their DC polarity as well as the alarm connection. 2-6.3 Wiring The Alarm Relay The single electrical relay can be wired into an alarm circuit and under normal condition it is connected as Normally Closed (will open upon alarm condition).
Hardware Installation Ring-type Fork-type terminal terminal 2-6.5 Ethernet Cabling For RJ-45 port connection, prepare twisted-paired, straight through Category 5/5e or above cables for Ethernet connection. The linking distance between the switch and the network device must be less than 100 meters (328 ft.).
