Toshiba VF-nC1 Compliance with UL Standard and CSA Standard, Compliance with Installation

E6581090

9.1.5Compliance with Low voltage directive

Please carry out the below mentioned countermeasures for the Low Voltage Directive in case of using VF-NC1 as components of your products.

(1)Inverter should be installed in a panel. Pay attention to wiring openings, so that it should prevent someone from touching live parts through the opening in case of maintenance.

(2)No more than 1 cable should be connected to one earth terminal of the main terminal board. In this case, other cables for ground should be grounded on the metal back plate and/or in the cubicle. The cross-sectional area of grounding cable shall be, in any case, not less than;

(3)MCCB or fuse should be connected to the input side of the EMI filter.

9.2Compliance with UL Standard and CSA Standard

The VF-NC1 models, that conform to the UL Standard and CSA Standard have the UL/CSA mark on the nameplate.

9.2.1Compliance with Installation

The VF-NC1 inverter must be installed in a panel, and used within the ambient temperature specification.

They can be used at ambient temperature of up to 50 degrees by peeling off the label on the top of the inverter.

9.2.2Compliance with Connection

Use the UL conformed cables (Rating 75℃ or more) with the ring terminal at wiring to the inverter input/ output terminals (R/L1, S/L2, T/L3, U/T1, V/T2, W/T3).

9.2.3Compliance with Peripheral devices

Use the UL listed fuses at connecting to power supply.

Refer to the instruction manual about selecting the rating of them.

Short circuit test is performed under the condition of the power supply short-circuit currents in below.

These currents and fuse currents depend on the applicable motor capacities.
