I. Application Scope
iTAC120M series intelligent phase-adjustable module is applicable to data center and other power distribution systems.

II. Structure Composition

iTAC120M series intelligent phase-adjustable module is mainly comprised of pluggable phasing part of the incoming line, outgoing line part and base.

Therein, the connection between incoming line part and incoming line of main power source is provided with the live pluggable phasing function; except that the power source is supplied to loading end on the outgoing line part, the built-in acquisition module can also acquire various electricity parameters for feeder on this branch circuit and implement the information interaction for communication baseplate of base and backstage so as to realize the system’s remote management.

▶Pluggable maintenance in live doesn’t affect other branch circuits’ power supply;
▶Easy phase selecting, three-phase loading for balanced system, onsite display for phase sequence;
▶RS485 communication function;
▶Support OF and SD of auxiliary installation contact;
▶Monitor the current, voltage, power, power factor, active and reactive power, power factor, electrical degree, harmonic wave and switch temperature, etc;
▶The rated current of components is designed to meet the application demand of 63A rated current rating and below;
▶All miniature circuit breakers both domestic and abroad as ABB, Schneider, Nader and Dem are compatible, and can be flexibly assembled as required.

1. The product can’t be exposed to rain during transportation & safekeeping and shall be placed or installed free from the invasion of rain.

2. The product shall be regularly inspected during operating, and the inspection period depends on the work condition, and the power supply shall be cut off during the inspection. The inspection items mainly include:

A. Remove the dust and dirt, and particularly remove the dirt between incoming and outgoing line levels.

B. Tighten the binding screws.

XI. Safety Precautions

1. While installing the products, the operation in live isn’t allowed so as to prevent the electric shock:

2. The live wire ( phase wire) to earth short-circuit or null wire ( neutral wire) and live wire touching method is not employed to test the product performance so as to avoid endangering the personal safety.

3. While installing, the wiring screw should be screwed up tightly, and the lead wire can’t loosen or pulled out easily, the cross section of lead wire should be selected strictly according to the requirement specified in this instruction;
