Compliance With Ul Standard And Csa Standard - Toshiba TOSVERT VF-S11 Instruction Manual

EN 50178 applies to electrical equipment intended specially for use in power installations, and sets out the
conditions to be observed for electric shock prevention when designing, testing, manufacturing and installing
electronic equipment for use in power installations.
6.1.4 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.

About the detail, refer to instruction manual E6581158 section 1.4.4 in the CD-ROM E6581167.
6.2.2 Compliance with Connection
Concerning the wires connecting input terminals (R/L1, S/L2, T/L3) and output terminals (U/T1, V/T2, W/T3),
please use the UL conformed cables (Rating 75 °C or more, copper conductor) with round crimp-type terminals.
Please refer to table "AIC, Fuse and Wire sizes" in 6.2.3 for recommended wire sizes.
Concerning the protection of branch cables, for installation in the United States, please follow the National
Electrical Code and local regulations to wire. For installation in Canada, please follow the Canadian Electrical
Code and local regulations to wire.
