TOSHIBA VF-S15 Inverter Complete Guide

If it is necessary to apply a lift, a mechanical brake must be added, and it cannot rely solely on the electrical brake of the frequency converter.

For situations where the automatic restart (F301) or retry function (F303) is activated, a warning label must be posted on the motor and equipment stating 'sudden start danger'.

CE/UL Compliance and EMC Measures

For equipment exported to the European or North American markets, VF-S15 must comply with the corresponding directives.

CE (EMC Directive 2004/108/EC):

Emission standard: IEC61800-3 C1 or C2 category (depending on motor wire length and filter).

Measure: Shielded motor cables and control cables must be used. Install EMC filters on the input side (some models have built-in filters, such as single-phase 240V and three-phase 500V). The grounding of the EMC board (optional) and shielding layer must be reliable (fixed with metal clamps, with a large contact area).

Leakage current impact: When there is a long line or high carrier, the leakage current increases, which may cause misoperation of the leakage protector. It is recommended to use high-frequency countermeasure type residual current circuit breakers or reduce the carrier F300.

UL/cUL：

Applicable models: All models with UL/CSA markings.

Branch circuit protection: UL certified Class J or Class CC fuses must be used (see Table I-7 in the manual). For example, the 200V 4.0kW model requires a Class J 45A fuse.

Environmental temperature: 240V 0.75kW and below models, UL compliance requires environmental temperature ≤ 40 ℃.

Short circuit withstand current (SCCR): It needs to be matched with a specified type of circuit breaker or fuse to reach 100kA.
