(3) Low Voltage Directive
We have self-confirmed our inverters as products
compliant to the Low Voltage Directive (Conforming
standard EN 50178 for ,
EN61800-5-1 for ) and place the CE mark on
the inverters.
Outline of instructions
• Do not use an earth leakage circuit breaker as an
electric shock protector without connecting the
equipment to the earth. Connect the equipment
to the earth securely.
• Wire the earth (ground) terminal independently.
(Do not connect two or more cables to one
terminal.)
• Use the cable sizes of earth cable and main
circuit under the following conditions.
• Ambient temperature : 40 maximum
If conditions are different from above, select
appropriate wire according to EN60204
ANNEX C TABLE 5.
• Use a tinned (plating should not include zinc)
crimping terminal to connect the earth (ground)
cable. When tightening the screw, be careful not
to damage the threads.
For use as a product compliant with the Low
Voltage Directive, use the recommended PVC
cable .
• Use the moulded case circuit breaker and
magnetic contactor which conform to the EN or
IEC Standard. Design notice : Where residual-
current-operated protective device (RCD) is used
for protection in case of direct or indirect contact,
only RCD of Type B is allowed on the supply side
of this Electronic Equipment (EE). Otherwise
another protective measure shall be applied such
as separation of the EE from the environment by
double or reinforced insulation or isolation of EE
and supply system by a transformer. (Extract
from EN51078)
• When using an earth leakage current breaker,
use a residual current operated protective device
(RCD) of type B (breaker which can detect both
AC and DC). If not, provide double or reinforced
insulation between the inverter and other
equipment, or put a transformer between the
main power supply and inverter.
• Use the inverter under the conditions of
overvoltage category II (usable regardless of the
earth (ground) condition of the power supply),
overvoltage category III (usable with the earthed-
neutral system power supply 400V class only)
and pollution degree 2 or lower specified in
IEC664.
• To use the inverter of 30K or more or
37K or more (IP00) under the
conditions of pollution degree 2, install it in
the enclosure of IP2X or higher.
• To use the inverter under the conditions of
pollution degree 3, install it in the enclosure of
IP54 or higher.
• To use the inverter of 22K or less,
30K or less, or (IP20)
outside of an enclosure in the environment of
pollution degree 2, fix a fan cover with fan
cover fixing screws enclosed.
• On the input and output of the inverter, use
cables of the type and size set forth in EN60204
Appendix C.
• The operating capacity of the relay outputs
(terminal symbols A1, B1, C1, A2, B2, C2) should
be 30VDC, 0.3A. (Relay outputs are basically
isolated from the inverter internal circuit.)
• Control circuit terminals are safely isolated from
the main circuit.
• Environment

Conformance Guide" (BCN-A21041-203). Please
