Hitachi S1 Series User Manual

S1 series standard inverter
-203-
Inverter categories
C1: Rated voltage lower than 1000 V, applied to environments of Category I.
C2: Rated voltage lower than 1000 V, non-plug, socket, or mobile devices; power drive systems that
must be installed and operated by specialized personnel when applied to environments of Category I
Note: The EMC standard IEC/EN 61800-3 no longer restricts the power distribution of inverters, but it
specifies their use, installation, and commissioning. Specialized personnel or organizations must
have the necessary skills (including the EMC-related knowledge) for installing and/or performing
commissioning on the electrical drive systems.
C3: Rated voltage lower than 1000 V, applied to environments of Category II. They cannot be applied
to environments of Category I.
C4: Rated voltage higher than 1000 V, or rated current higher or equal to 400 A, applied to complex
systems in environments of Category II.
10.6.1 Inverter category of C2
The induction disturbance limit meets the following stipulations:
1. Select an optional EMC filter according to Chapter 12 and install it following the description in the
EMC filter manual.
2. Select the motor and control cables according to the description in the manual.
3. Install the inverter according to the description in the manual.
4. For the maximum length of the motor cable, see section "EMC compatibility and motor cable
length".
 Currently in environments in China, the inverter may generate radio
interference, you need to take measures to reduce the interference.
10.6.2 Inverter category of C3
The anti-interference performance of the inverter meets the requirements of environments Category II
in the IEC/EN 61800-3 standard.
The induction disturbance limit meets the following stipulations:
1. Select an optional EMC filter according to Chapter 12 and install it following the description in the
EMC filter manual.
2. Select the motor and control cables according to the description in the manual.
3. Install the inverter according to the description in the manual.
4. For the maximum length of the motor cable, see section "EMC compatibility and motor cable
length".
 Inverters of C3 category cannot be applied to civilian low-voltage common
grids. When applied to such grids, the inverter may generate radio frequency
electromagnetic interference.
