Page 2: Overview
Redundancy • Therefore inclusion of INFORM Static Transfer Switches (STS) in an energy distribution system provides secure protection against any possible faults in the AC power system. STS permits switching between two independent AC power supplies (SOURCE 1 and SOURCE 2) without shutting down the critical load connected to its output. - Page 3 During normal operation, “PREFERRED” network supplies the load when both inputs are available. Selection of the “PREFERRED” network, automatic re-transfer, retransfer delay, overload behavior of STS, alarm hold time, nonsynchronized transfer behavior, overload and transfer inhibit reset modes may be set by the user on the control panel of the unit.
- Page 4 Protections - Two input sources are connected to STS by MCCB’s (S1 and S2) - Suitable rating varistors protect the control circuits from high voltage transients. - All power supply inputs are fuse protected On SCR’s heat-sink, there is a thermal contact to warn the user in case of excessive heat-sink temperature. Protection shield prevents direct touch to live parts, inside the unit.

Page 17: Wiring Procedure
WIRING PROCEDURE Open the STS cabinet front door and remove the metal guard on the lower side to permit access to the connection terminals and busbars (neutral and earth). Before connecting any power cables, please ensure that all the circuit breakers on the STS are in “OFF” position. (S1, S2, S3 and S4) SOURCE 1 Input Power Connections Connect the SOURCE 1 AC power cables to the terminals U1-V1-W1 of the STS (Figure 7,8,9,10) and tighten the connections properly. -
Page 18: Use
DESCRIPTION The purpose of the STS is to select one of two input power lines which is in tolerant with predefined limits. Users must decide that one of the input sources must have priority (preferred source) the other source is alternate source. -
Page 19: Switching On (Normal Operation) The Sts From Off Position
Switching On (Normal Operation) The STS From Off Position Ensure again that the Maintenance Bypass Switch (S4) is in “0” position and it is locked for safety. 1) Ensure that maintenance bypass switch (S4) is in 0 position (center) 2) Turn on input switches (1 position) S1 and S2. The STS control circuits will be energized and will start functioning. -
