Thin Web Server
The ASCO 5500 Series Catalog A5510 Thin Web Server (TWS) provides real-time monitoring and control of ASCO Automatic Transfer Switches and engine-generator sets over the Internet or an intranet. The TWS also logs critical alarms and analog information.
The TWS has a chassis ground point on the top left corner. Back out the screw and connect a braided lead as short as possible to earth ground.
The TWS can be used with ASCO 4000 & 7000 Series and Series 300 Automatic Transfer Switches that have Accessory 72A Communication Interface Modules.
