TOSBERT VF-AS3 Industrial Inverter Quick Start Manual

TOSBERT VF-AS3 Industrial Inverter Quick Start Manual

The fast start manual for Toshiba TOSBERT VF-AS3 series industrial frequency converters covers three voltage levels of 500V/600V (575V)/690V and a power range of 1.5kW-75kW/2HP-100HP. The core content includes safety specifications, installation wiring, standard compliance measures, peripheral equipment selection, parameter settings, product specifications, and warranty terms. It emphasizes the need for professional operation, clarifies the compliance requirements for multi rating settings (HD/ND), EMC/UL/CSA, and safety taboos such as high voltage operation and capacitor discharge, and is suitable for controlling the speed of three-phase induction motors, IPMSM, and SPMSM.

1. Basic information

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
