Conformity to the Low Voltage Directive in the EU
If installed according to the guidelines given below, inverters marked with CE are considered as compliant with
the Low Voltage Directive.
Compliance with European Standards
Adjustable speed electrical power drive systems (PDS).
Part 5-1: Safety requirements. Electrical, thermal and energy. IEC/EN 61800-5-1
1. The ground terminal G should always be connected to the ground. Do not use only a
residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB)* as the sole
method of electric shock protection. Be sure to use ground wires of recommended size listed on page vii.
*With overcurrent protection.
2. To prevent the risk of hazardous accidents that could be caused by damage of the inverter, install the
specified fuses in the supply side (primary side) according to the following tables.
- Breaking capacity: Min. 10 kA
- Rated voltage: Min. 500 V

*1) Not more than 6A (RMS) fuses or not more than 5A (RMS) breakers for 24V power supply and
control power supply (R0 and T0). Fuse class: IEC/EN 60269-1 or 60269-2
*2) The recommended fuse type is applicable to the inverter equipped with a DC reactor only.
Be sure to use a DC reactor.
3. When used with the inverter, a molded case circuit breaker (MCCB), residual-current-operated protective
device (RCD)/earth leakage circuit breaker (ELCB) or magnetic contactor (MC) should conform to the EN
or IEC standards.
4. When you use a residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB)
for protection from electric shock in direct or indirect contact power lines or nodes, be sure to install type B
of RCD/ELCB on the input (primary) of the inverter.
