Chapter 1
1.4 Compliance to European Directive
(CE)
1.4.1 Caution for EMC (Electromagnetic
Compatibility)
The SH1 series inverter conforms to requirements of
Electromagnetic Compatibility (EMC) Directive (2014/30/EU).
However, when using the inverter in Europe, you must comply
with the following specifications and requirements to meet the
EMC Directive and other standards in Europe:
WARNING: This equipment must be installed, adjusted,
and maintained by qualified engineers who have expert
knowledge of electric work, inverter operation, and the
hazardous circumstances that can occur. Otherwise,
personal injury may result.
1. Power supply requirements
a. Voltage fluctuation must be -15% to +10% or less.
b. Voltage imbalance must be ±3% or less.
c. Frequency variation must be ±4% or less.
d. Total harmonic distortion (THD) of voltage must be ±10% or
less.
2. Installation requirement
a. SH1 series (SH1-03160-H(SH1-1320H)and below) includes a
built-in EMC filter. The built-in EMC filter must be activated.
b. According to EN61800-3 it is mandatory to mention that
any inverter with only C3 filter inside may NOT be
connected to a low voltage public power supply in
residential areas since for these installations C1 is required.
c. In case of external filter for C2, an additional note is
required according to EN61800-3 that "this product may
emit high frequency interference in residential areas which
may require additional EMC measures".
d. According to the EN6100-3-12, an additional AC reactor or
DC choke should be installed for reducing harmonics in
power line.
3. Wiring requirements
a. A shielded wire (screened cable) must be used for motor
wiring, and the length of the cable must be according to the
following table (Table 1 on page 1-5).
b. The carrier frequency must be set according to the
following table to meet an EMC requirement (Table1 on
page 1-5).
c. The main circuit wiring must be separated from the control
circuit wiring.
4. Environmental requirements
(When an EMC filter is used)
a. SH1 series inverter (SH1-03160-H(SH1-1320H)and below)
that is activated built-in EMC filter must be according to SH1
series specifications.
