Specifications for INEX 100A STS Module and MBS+PDU
DC Auxiliary Power Input
Operating Range: 40 to 60Vdc within rated limits
AC Input
Voltage Range: 110/115/120Vac: 89 to 138Vac

Under Voltage Threshold: 176 / 89Vac
Back-feed Protection: Comply with safety requirement
Redundant Power Supply Design: Startup by priority source or alternative
NOTE: the over/under voltage must be set by controller, if there is no additional setting, STS will adopt the widest range
to set over/under voltage in order to guarantee its performance, for 110/115/120Vac system, the range is 89Vac
(under voltage point) to 138Vac (over voltage point), for 208/220/230/240Vac system, the range is 176Vac (under
voltage point) to 276Vac (over voltage point). But once the STS is set by user, it will keep the setting whether a
controller exists or not, until such time that the STS is set by user again or next time the source connected to STS
is changed from 120V (110/115/120) to 230V (208/220/230/240) or 230V (208/220/230/240) to 120V

Before using the product, read all instructions and cautionary markings on the product and any equipment
connected to the product.
This unit is designed for indoor use only. Do not expose the product to rain or snow; install only in a clean, dry
environment.
CAUTION – To reduce the risk of fire hazard, do not cover or obstruct the ventilation openings. Do not install the
inverter in a zero-clearance compartment.
CAUTION – Unless otherwise noted, use of an attachment not recommended or sold by the product manufacturer
may result in a risk of fire, electric shock, or injury to persons.
CAUTION – Do not operate the product if it has received a sharp blow, it has been dropped, or otherwise
damaged in any way – return it to a qualified service center for repair.
CAUTION – Do not disassemble the product – call our qualified service centers for servici ng. Incorrect
reassembling may result in a risk of electrical shock or fire.
WARNING – The input and output voltages of the product are hazardous. Extreme caution should be maintained
when servicing or touching conductive components conne cted to the product.
Mechanical Safety
Power equipment can reach extreme temperatures under load.
Use caution around sheet metal components and sharp edges.
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.
• Use OSHA approved insulated hand tools.
Do not work alone under hazardous conditions.
Ensure no liquids or wet clothes contact internal components.
Battery Safety
Servicing and connection of batteries shall be performed by, or under the direct supervision of, personnel
knowledgeable of batteries and the required safety precautions.
Never reverse DC+ and DC- to battery.
Keeps the battery away from heat sources including direct sunlight, open fires, microwave ovens and high-voltage
container. Temperatures over 60ºC may cause damage. Make sure the area around the battery is well ventilated.
Always wear eye protection, rubber gloves, and a protective vest when working near batteries. Remove all
metallic objects from hands and neck.
Use OSHA approved insulated hand tools. Do not rest tools on top of batteries.
Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
Batteries contain or emit chemicals known to the State of California to cause cancer and birth defects or other
reproductive harm. Battery post terminals and related accessories contain lea d and lead compounds; wash hands
after handling (California Proposition 65).
If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters your eye,
immediately flood it with running cold water for at least twenty minutes and get medical attention immediately.
If you need to remove a battery, always remove the grounded terminal from the battery first. Make sure all
accessories are off so you don’t cause a spark.
WARNING
Follow battery manufacturer’s safety recommendations when working around battery systems.
WARNING
Do not smoke or present an open flame when batteries (especially vented batteries) are on
charge. Batteries vent hydrogen gas when on charge, which creates an explosion hazard.
Batteries are hazardous to the environment and should be disposed of safely at a recycling facility. Consult the
battery manufacturer for recommended local authorized recycl ers.

1.2 Product Overview
The STS (Static Transfer Switch) module increases system reliability by automatically switching between the
inverter output and the AC mains. By setting up the priority of operation mode, users can change the system
status of “on line mode” or “off line mode”. The on line mode will keep the input power provided by inverter line
and when inverter fails, the line will switch to AC utility line. In off line mode, the system power is always
connected to the AC utility line and will switch to inverter power line when AC utility fails. The transfer time is less
than 1/4 cycle which can avoid the power interruption. The reliable performance of the STS module can provide
the maximum protection to the connected telecommunication equipment against possible da mage caused by the
system power failure.
STS Module Features:
• Small footprint and weight
• Universal input range
• Hot-swap replacement in shelf (w/ MBS option)
• Back-feed protection
• Redundant fan design
• Fast transfer time, typically less than 1/4 cycle
• Low audible noise <55dBa
• No cross connect
• Optional maintenance bypass switch function
• Operation Priority Setup of transfer side by setting in Control Module
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.

STS-100 transfers the critical load between power sources in less than 1/4 cycle upon loss of sou r ce. The fast
transfer enables further redundancy in distribution, adding level of availability, flexibility and reliability to our
customer’s power infrastructure.
