TOSBERT VF-AS3 Industrial Inverter Quick Start Manual

1. Basic information

Product positioning: Used for controlling the speed of three-phase induction motors, built-in permanent magnet synchronous motors (IPMSM), and surface permanent magnet synchronous motors (SPMSM) in industrial scenarios, and cannot drive single-phase motors

Voltage and power range:

500V level: 1.5kW-55kW

600V (575V) level: 2HP-75HP (HD)/3HP-100HP (ND)

690V level: 2.2kW-75kW (HD)/3kW-90kW (ND)

Core features: Supports multiple ratings (HD/ND), V/f control, vector control, PID control, built-in EMC filter and DC reactor

2. Core security standards

2.1 Personnel and Protection Requirements

Qualification requirements for homework types require necessary protective equipment

All qualified installation/maintenance personnel shall wear protective gloves and safety work clothes

Electrical work requires the qualification of insulated gloves, insulated shoes, and anti electric shock clothing

High altitude operations (≥ 50cm) require industrial safety helmets with high-altitude operation qualifications and ladders that comply with ISO14122 standards

Shoes for heavy object transportation (≥ 20kg) without special qualifications but requiring training on anti smashing toe caps

Qualified maintenance personnel with electrician specific protective gloves for maintenance operations

2.2 Key safety taboos

High voltage operation: After power failure, wait for 15 minutes (capacitor discharge), confirm that the charging light is off and the DC voltage is ≤ 45V before operation

Prohibited behavior:

Do not disassemble the front cover/small front cover (including high-voltage components inside) while it is live

Do not connect the power supply to the output terminals [U/T1] [V/T2] [W/T3]

Do not modify equipment or use non specified accessories

Prohibit the use of welding machines in enclosed spaces (to prevent carbon monoxide poisoning)

Power requirement: Do not connect the corner grounding system, IT system needs to disconnect the grounding capacitor

​3. Installation and wiring

3.1 Installation environment and conditions

Remarks on the Range of Environmental Parameter Requirements

If the ambient temperature is between -15 ℃ and+60 ℃ and exceeds 50 ℃, it is necessary to reduce the capacity for operation

Relative humidity 5%~95%, no condensation

Altitude ≤ 2000m>1000m, capacity reduction of 1% per 100m

Vibration ≤ 5.9m/s ² (10-55Hz) Avoid installation in locations with high vibration

Installation location: Indoor, no direct sunlight, no corrosive gas/oil mist, ventilation space needs to be reserved

3.2 Installation and wiring specifications

Installation method:

Wall mounted installation: NEMA Type 1 kit is required (NEM301Z for A1Y, NEM302Z for A2Y)

Multiple parallel devices: A1Y spacing ≥ 11mm, A2Y spacing ≥ 11mm, with a ventilation space of ≥ 10cm reserved above and below

Wiring requirements:

Power terminal: [R/L1] [S/L2] [T/L3] (three-phase input)

Motor terminals: [U/T1] [V/T2] [W/T3] (three-phase output)

Grounding terminal: [PE], wire diameter needs to be matched (such as 600V HD type 12AWG corresponding to grounding 12AWG)

Terminal torque: A1Y 12AWG is 26.5lb · in, A2Y output terminal is 363lb · in

AUL (Multiple Rating Selection): Select HD/ND and voltage levels 2 (ND-600V), 3 (HD-600V), etc. 3 (HD-600V -60Hz)

4.2 Differences in Multiple Rated Values (HD/ND)

Rated Value Type Overload Capacity Applicable Scenario Parameter Setting (AUL)

HD (Heavy Duty) 150% -60s constant torque load (conveyor, crane, etc.) 3 (600V), 15 (500V), 17 (690V)

ND (Normal Duty) 120% -60s variable torque load (fan, pump, blower, etc.) 2 (600V), 14 (500V), 16 (690V)

5. Standard compliance measures

5.1 Main Compliance Standards

Key measures for compliance requirements of standard types

The EMC directive complies with IEC61800-3, CISPR11 with built-in EMC filters, shielded cables, and separate wiring

Low voltage instructions comply with IEC61800-5-1 for installation in cabinets, standardized grounding, and installation of protective devices

UL/CSA standards comply with UL61800-5-1, using UL certified cables and installing specified fuses/circuit breakers

ATEX directive not applied for and cannot be used in explosion-proof scenarios
