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: EN50178
Electronic equipment for use in power installations
Electronic equipment for use in power installations
Pollution level: 2 (5.2.15.2)
Overvoltage category: 3
200V class - 3.0mm (5.2.16.1)
400V class - 5.5mm (5.2.16.1)
EN 50178 applies to electrical equipment intended specially for use in power installations, and sets out the condi-
tions to be observed for electric shock prevention when designing, testing, manufacturing and installing electronic
equipment for use in power installations.
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)
Do not connect two or more wires to the main circuit earth terminal of the inverter. If necessary, install an
additional earth terminal on the metal plate on which the inverter is installed and connect another cable to it.
Or install the EMC plate (attached as standard) and another cable connect to earth terminal on the EMC
plate. Refer to the table 10.1 for earth cable sizes.
(3)
Install a non-fuse circuit breaker or a fuse on the input side of the inverter.
