9.1.3 About the Low Voltage Directive
The Low Voltage Directive provides for the safety of machines and systems. All Toshiba inverters are CE-marked
in accordance with the standard EN 50178 specified by the Low Voltage Directive, and can therefore be installed
in machines or systems and imported without problem to European countries.
Applicable standard: IEC61800-5-1
Pollution level: 2
Overvoltage category: 3
9.1.4 Measures to satisfy the Low Voltage Directive
When incorporating the inverter into a machine or system, it is necessary to take the following measures so that
the inverter satisfies the Low Voltage Directive.
(1) Install the inverter in a cabinet and ground the inverter enclosure. When doing maintenance, be extremely
careful not to put your fingers into the inverter through a wiring hole and touch a charged part, which may
occur depending on the model and capacity of the inverter used.
(2) Connect earth wiring to the earth terminal on the EMC plate. Or install the EMC plate (attached as
standard) and another cable connect to earth terminal on the EMC plate. Refer to the table in 10.1 for
details about earth cable sizes. A minimum wire size of 10mm
2
may be required to meet standards limiting
leakage current.
(3) Install a non-fuse circuit breaker or a fuse on the input side of the inverter. (Refer to section 10.1 and 9.2.3)
9.2 Compliance with UL Standard and CSA Standard
This inverter that conform to the UL Standard and CSA Standard based on the rated current of the nameplate
have the UL/CSA mark on the nameplate.
9.2.1 Compliance with Installation
A UL certificate was granted on the assumption that the inverter would be installed in a cabinet. Therefore, install
the inverter in a cabinet and if necessary, take measures to maintain the ambient temperature (temperature in the
cabinet) within the specified temperature range. (Refer to section 1.4.4)
9.2.2 Compliance with Connection
Use the UL conformed cables (Rating 75 °C or more, Use the copper conductors only.) to the main circuit
terminals (R/L1, S/L2, S/L2/N, T/L3, U/T1, V/T2, W/T3).
For instruction in the United States, Integral solid state short circuit protection does not provide branch circuit
protection. Branch circuit protection must be provided in accordance with the National Electrical Code and any
additional local codes.
