1. Voltage range
- Units are suitable for use on electrical systems where voltage supplied to unit terminal is not below or above listed range
limits
2. Maximum allowable voltage variation between phases is 2%.
3. Wire size & type must comply with the applicable local and national code.
- Wire size : Based on the value of MCA.
- Wire type : 60245 IEC57(IEC) or H05RN-F(CENELEC) grade or more.
4. MFA is used to select the circuit breaker and the ground fault circuit interrupter (earth leakage circuit breaker).
5. MCA represents maximum input current.
MFA represents capacity which may accept MCA
Abbreviations
- MCA : Min. Circuit Amps. (A)
- MFA : Max. Fuse Amps. (A)
6. This equipment complies with IEC 61000-3-12 provided that the short-circuit power Ssc is greater than or equal to Ssc(*2)
at the interface point between the user’s supply and the public system. It is the responsibility of the installer or user of
the equipment to ensure, by consultation with the distribution network operator if necessary, that the equipment is
connected only to a supply with a short-circuit power Ssc greater than or equal to Ssc(*2).
