Step 1: Install and Mount Control Panel

Mount the enclosure to a non-vibrating surface using the provided mounting brackets. Install the back plate with the four nuts provided.

Step 2: Run and Terminate Single-Phase Input Wiring

Connect both hot conductors (L1 and L2) from your single-phase electrical panel to the terminals marked L1 and L2 on the phase converter input.

Step 3: Install Idler Motor and Connect Motor Wiring

Follow the motor diagram for proper connections. Never use wire nuts on motor connections - use Polaris connectors or bolt-down lugs only.

Step 4: Run and Terminate Three-Phase Output Wiring

Connect the three-phase output (T1, T2, T3) to your load distribution panel or motor starter.

Step 5: Verify All Connections and Torque Specifications

Check all connections for proper torque and electrical continuity before energizing the system.

Step 6: Energize and Test System

Power up the converter first, then connect your load. Never start the phase converter under load.

Identify Full Load Amperage (FLA)

Check the equipment's nameplate or manual for the FLA—this is the current the equipment draws under full load.

Determine Breaker Size Based on NEC Guidelines

Motors: Per NEC Article 430, breakers are sized 125% of the motor's FLA (for inverse time breakers).

Resistive loads: Breaker can be sized at 100% of the rated current (plus safety margin if continuous load).

Use Manufacturer Recommendations

Always refer to the equipment manual. Some equipment may require a dedicated breaker size due to sensitive electronics or startup characteristics.

Add Up All Individual Loads

Calculate the total amperage of all connected equipment. Add the FLA of all machines that can run at the same time. Don't add everything blindly—only count simultaneous loads.

Apply Diversity Factors

If all equipment will not run at once, apply a diversity/load factor (e.g., 70–80%) to total amps. NEC allows certain reductions when sizing for non-continuous loads or when motors start in sequence.

Include Largest Motor Adjustment

Per NEC 430: Add 125% of the largest motor's FLA, then add the FLA of all other motors.

Choose the Right Breaker

Based on total adjusted amperage, choose the next standard breaker size up (per NEC 240.6). Verify the breaker is compatible with the panel and wire size.

Connect Single Phase Input

Run both hot conductors (Line 1 and Line 2) from your single-phase electrical panel and connect them to the terminals marked L1 and L2 on the phase converter input.

Connect Idler Motors

Run a total of four conductors on each idler—three power lines and one ground wire—from each idler motor to the terminal block. Terminate at terminals labeled L1, L2, and L3.

Connect Output Load

Choose between independent operation (single idler) or combined operation (both idlers) based on your load requirements.

Converter Won't Start

• Check: Input voltage and connections
• Check: Control power (if applicable)
• Check: Idler motor connections
• Check: Input breaker sizing

Low Output Voltage

• Check: Input voltage level
• Check: Wire sizing for voltage drop
• Check: Connections for loose terminations
• Check: Load balance across phases

Converter Trips Breaker

• Check: Breaker sizing (use motor load breaker)
• Check: Starting sequence (converter first, then load)
• Check: Load amperage vs. converter capacity
• Check: Short circuit conditions

Poor Load Performance

• Check: Phase converter sizing vs. load
• Check: Voltage balance at load
• Check: Motor starter and overload settings
• Check: Load wiring connections
