IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS This section contains important instructions that should be followed during the installation and maintenance of equipment and batteries. Please read all of the instructions before operating the equipment, and save this manual for future reference.
Electrical Safety WARNING To avoid a risk of fire and electric shock, make sure that existing wiring is in good condition and that wire is not undersized. Do not operate the inverter with damaged or substandard wiring. Before working with any live battery or power system, follow these precautions: • • • Remove all metallic jewelry; e.g., watches, rings, metal rimmed glasses, necklaces. Wear safety glasses with side shields (and prescription lenses if necessary) at all times during installation.

1 Introduction 1.1 Scope of the Manual This instruction manual explains the features, installation, startup and maintenance of the INEX 100A STS Module and MBS+PDU. NOTE: Images contained in this document are for illustrative purposes only and may not exactly match your installation. 1.2 Product Overview The STS (Static Transfer Switch) module increases system reliability by automatically switching between the inverter output and the AC mains.
1.3 Illustration of Operation STS-100 is designed to avoid operational disruptions of critical loads. This automatic static transfer switch (STS) automatically transfers critical loads from the primary AC power source to an alternative AC power source in the event of interruption or abnormal conditions.

1.5 Voltage and Frequency Range The STS module has two voltage inputs and one voltage output. The two inputs are Mains voltage and Inverter voltage, and the output is System (output) voltage. STS will detect Mains voltage and Inverter voltage in order to decide system’s supply mode when system is running.
2 Inspection 2.1 Packing Materials All Argus products are shipped in rugged, double walled boxes and suspended via solid inserts to minimize shock that may occur during transportation. Packaging assemblies and methods are tested to International Safe Transit Association standards. 2.1.1 Returns for Service Save the original shipping container. If the product needs to be returned for service, it should be packaged in its original shipping container.

Continue the inspection for any internal damage. In the unlikely event of internal damage, please inform the carrier and contact Argus Technologies for advice on the consequence of any damage. Verify that you have all the necessary parts per your order for proper assembly.
3 Installation 3.1 Location Unit is designed for installation in a protected environment. Factors to be considered in selecting a location include ventilation, temperature, humidity, and accessibility. Install the unit in a clean, dry location with an unrestricted air flow and sufficient space for rear and front access. Unit will provide its full capability in ambient temperatures from -5°C to 50°C. Higher ambient temperatures will lead to a shorter life.
3.2.2 Install MBS/PD Chassis 1. The MBS/PD chassis is also pre-installed with 19-inch rack brackets. For 23-inch rack mounting, please exchange with the proper mounting brackets. 2. Put the MBS/PD chassis to the equipment rack horizontally above the STS shelf, and align holes of mounting brackets and rack. Secure the chassis in position with four cross pan type nickel screws as shown: Figure 7–Mounting the MBS/PD chassis to the equipment rack 3.
4 Wiring Before selecting the wiring, consider the following factors: • • • Current carrying capacity of the wire Maximum wire length needed Maximum ambient temperature. IMPORTANT Use the table below as a guide only. Ensure that the installation complies with the specific wiring rules applicable to your country or area of jurisdiction.
4.1 Inverter Shelf Wiring With STS Chassis CAUTION Shut down all the power sources before wiring. Disconnect battery cables from battery. Please follow the wiring instructions for your needs. 1. Locate the CN11 connector on the rear panel of STS shelf and CN7 connector on the rear panel of the inverter shelf.
4. Connect DC input wires – put both wires through the wire hole on the left side of the inverter shelf. Use the cross pan type nickel screws, in the accessory kit, for fixing both DC INPUT wires. 5. Connect AC output/input/ground wires. CAUTION To connect AC output wires onto the system, only one AC line and AC Neutral are necessary to be connected either from STS shelf or inverter shelf. User should knock out the hole for cable on STS shelf and add a protect circuit.

Connect signal cable between MBS/PDU, STS shelf. Connect the 4-pin MBS cable to the CN1 connector on the back PCB of the controller/interface/STS shelf.
3. Connect DC INPUT wires. Put both wires through the wire hole on the left side of the inverter shelf. Use the hex washer type nickel screws, in the accessory kit, for fixing both DC INPUT wires. 4. Connect AC output/input/ground wires. Connect AC input to the terminal on the back left of MBS/PDU according to the position of the silkscreen. Screw the back cover onto the STS & Controller shelf.

5 STS Module Installation 1. To install STS module, slide it into a pre-wired chassis until the face plate is flush with the mounting ears. In order to prevent the STS module from being displaced, turn the lock bolt left to lock position. 2. At power on, the STS unit enters into a self-diagnostic mode. If everything is functioning correctly, the indicator will remain solid green, and STS will detect and transfer the better quality power to the load. 3. Remove the module by pulling outward. 4.
6 Operation The operation mode of STS is closely linked with the position of MBS. MBS has two main connectors and three assistant connectors. The signal generated by three assistant connectors are passed to DSP for position detection. Once an assistant connector is closed, the signal generated is logic 0, in reverse, the signal will be logic 1, the combination of logic 0 and 1 forms eight kinds of status, there are five kinds of valid status.

7 Maintenance and Troubleshooting 7.1 Preventative Maintenance The following preventive maintenance routines should be considered as a minimum requirement. Your installation and site may require additional preventive maintenance to assure optimal performance from your installed inverter and associated equipment. These routines should be performed twice a year (more often if required). We strongly recommend a contract with Customer Support Services for preventive and remedial maintenance.
