1.5 Warranty Static Power operating through its authorised agents warrants that the standard products will be free of defects in materials and workmanship for a period of 24 months after the date of invoice, or such other period as may be specified. -
Page 6: System Overview & Operation
2. SYSTEM OVERVIEW & OPERATION 2.1 Description A Static Transfer Switch (STS) provides seamless switching between two power sources to provide interrupted power to a critical load. The iSTS continuously monitors the supply sources for failure or degeneration and switches automatically to the alternate source as required to protect the load against failure. -

3.3 Installation ▪ The STS unit should be bolted to the floor using the provided mounting rails. The STS should have at least 100mm of space between the back, sides and any walls, with 1400mm in front of the ▪ STS, as shown in the diagram below 100mm 100mm... -
Page 11: Cable Termination To The Ists
G 3.4 Cable Termination to the iSTS It is important that the cables are run in accordance with any local regulations. The cable entry space may be at the top or bottom depending on the unit. The gland plate covering the cable entry space must have a hole cut into it to fit the cable runs. - Page 12 12. Confirm these values on the UI LCD. 13. Simulate supply failures and observe the unit transfer: ie. While on S1, fail S1; while on S2, fail S2. Observe that the STS transfers okay. 14. Review the event list. Taking note of any COMMS or SCR events. After initial power up: After a few seconds the display screen will power up and you will be prompted to enter the date and time.

G 4. USER INTERFACE 4.1 Preferred Switch This switch allows the preferred source to be set to Supply 1, Supply 2 or None (0), which will take affect only when the preferred source is set to None (0) on the iSTS software. Refer to the Web Interface section for instructions on changing the preferred source through LAN connectivity. -

G 5. DISPLAY SCREEN 5.1 Home Screen A colour touch-screen LCD provides the user with an easy to navigate real-time information and control interface. Touch feedback is indicated by an audible ‘beep’. 5.2 Status & Alarms The Home/Status screen shows a mimic diagram and status indication as text. This is the default screen, and a period of inactivity will result in the LCD returning to this location. -

5.4 Manual Transfers Press and hold the transfer button for 3 seconds to affect a transfer. This transfer touch zone can be removed if desired (to make the install more secure) via the “Control” menu and selecting the “Allow Transfer”, “OFF” option. The unit can still be transferred using the priority switch at the rear of the STS. -
Page 17: Events
G 5.6 Events Up to 200 events can be stored. Once the list is full, the oldest events are pushed from the bottom of the list and are replaced by any new events. See the Fault Codes section for more information. -
Page 18: Settings
The settings should not be changed unless the user has a full understanding of the consequences. Consult Static Power prior to changing any settings. All iSTS settings always must be wider than the source that is supplying the iSTS. -

Entering the IP address into the web browser address bar brings up the web server home page. If the DHCP/address have not yet been registered on your network you may need to remove the cable for 5 to 10 seconds and reconnect the cable, this in turn should re-register the device on the network. -

Page 27: Advanced Settings
G 6.6 Advanced Settings SETTINGS SCREEN NOTE: The STS has been shipped with factory defaults. These are the most reliable settings for correct stable operation. These settings should only be changed under the certain operating conditions, and it is advised that you consult with us before doing so, as wrong settings can make the system unstable and damage equipment. -
Page 28: Input Steady State Settings
6.7 Input Steady State Settings These figures define the upper and lower limits of deviation from the nominal voltage and current of the input power that creates the fault condition to trigger the alarm and record the event. S1 steady state high value (%) Default value of 115%, can be changed from a nominal value of 105 to 125. -

6.9 Output Settings Output steady state high value (%) The default value of 118%, can be changed from a nominal value from 105 to 135. This number will be set as a percentage. Averaging time constant for this parameter is defined by “Steady-state failure time” typically 1.5 seconds. Set as a percentage from nominal –... - Page 31 G Transfer timer The default setting value is “0” which disables this function. This parameter sets a period in seconds that the STS will undertake a test transfer to the alternate source. After a delay, the load will be returned to the original source. This function is used to test functionality and protections within the STS.

Page 32: Maintenance Bypass
7. MAINTENANCE BYPASS 7.1 Overview Maintenance bypass mode allows the load to be connected to one supply without going through the power circuit of the iSTS. In this mode, transferring the load to an alternate supply is not possible. The maintenance bypass mode should only be used to select the presently operating source. -
