Installation and wiring

1. Installation requirements

Environmental temperature conditions: 0-40 ° C (working), -5-40 ° C (storage); Humidity: 5-95% RH (no condensation) Avoid dust, corrosive gases, and vibration (<0.5G)

The installation spacing should be ≥ 25mm (1 inch) on both sides and ≥ 100mm (4 inches) on both sides to ensure heat dissipation. Multiple units should be placed side by side with gaps left

Cooling direction: The ribs of the cooling fins are vertically installed to assist with fan cooling, ensuring smooth airflow

The shell requirement is that open models should be installed in NEMA 1 (indoor) or NEMA 12 (dustproof and splash proof). The size of the inner and outer shells of the shell should meet the requirements of heat dissipation: for example, the shell volume of 18-481 should be ≥ 0.05m ³

2. Wiring configuration (key terminals)

(1) Power wiring (main circuit)

L1/L2/L3 (R/S/T) main power input three-phase 208-600VAC, requires circuit breaker/isolation switch TE2-18-BP: 10AWG, torque 35in lbs (M5 bolt)

T1/T2/T3 (U/V/W) motor output is connected to a three-phase motor, and reverse input/output TE2-1250-BP: 4 × 500kCMIL, torque TBD is strictly prohibited

The grounding terminal equipment shall be grounded according to NEC specifications, with a wire diameter not less than 1/2 of the phase wire. For example, a 10AWG phase wire shall be paired with an 8AWG grounding wire

(2) Control wiring (TB1 DC 24V, TB2 AC 120/240V)

TB1 (DC 24V) 1-3 3-wire control (Start/Stop) 1 connected to Start (NO), 2 connected to the common terminal, 3 connected to Stop (NC)

External interlock (NC) 4-5 connected to low oil level/high temperature switch, factory jumper needs to be removed

6-7 dual slope switch to external contacts, close and activate slope 2

7-8 Jog: Connect to external contacts, close to activate Jog (requires Start command)

9-10 analog output (4-20mA) connected to PLC/instrument, monitoring current/voltage/thermal capacity (F108 setting)

11-12 fault output (optocoupler Triac) connected to PLC, conducting in case of fault (240VAC/50mA max)

TB2 (AC control power supply) 21-22 (A1-A2) control power supply input 120VAC (standard), requires 1A fuse connection

Parameter programming

1. Core mandatory parameters

The rated current (FLA) of F001 motor must be set to the FLA on the motor nameplate, otherwise the soft starter will not operate. Range: 50-100%. The maximum current of the soft starter is 9-18A, such as TE2-18-BP

The service factor (SF) of F002 motor is set according to the motor nameplate, affecting the FLA upper limit 1.0 range of 1.00-1.30. If SF ↑, F001 can be set within the range ↓

F003/F004 Start/Run Overload Level NEMA Class 5-30, Match Motor Overload Capacity 10 (Class 10) Set High Level (e.g. Class 20) during Start to Avoid False Alarm

F010 Slope Type Selection: Choose Voltage/Current Slope and Double Slope Combination 1 (VR1+VR2). For heavy loads, choose CR, and for light loads, choose VR

F014/F018 maximum current limit limits the starting current and protects the power grid and motor by 350%. When the FLA power grid capacity is small, set it low (such as 250%), and when overloaded, set it high (such as 500%)
