Installation
Power requirements
General
This equipment complies with IEC 61000-3-12 provided that the short-circuit power Ssc is greater than or equal to
5.61 MVA at the 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 5.61 MVA.
All switches, slow-blow fuses and power cables are customer-supplied and must be chosen as outlined by applicable
national and local electrical codes. Installation must be performed by a licensed electrician. Use a separate, primary, line
disconnect switch for the power supply. Recommendations on fuse and circuit breaker sizing are listed below, however
actual sizes required will vary based on individual site electrical line conditions (including but not limited to: source
impedance, line impedance, and line voltage fluctuation), product inrush characteristics, and regulatory requirements.
The main feed protection device (circuit breaker or fuse) must be sized to handle all branch-feed loads for both inrush and
steady-state current. The power supply must be wired into one of the branch-feed circuits. The power supply has a
steady-state current listed in the table below.
Use a motor-start circuit breaker or equivalent if time delay high inrush fuses are not permitted by local and national
codes. Time delay fuses and circuit breakers must be capable of withstanding inrush current that is up to 30 times the
rated input current (FLA) for 0.01 seconds and up to 12 times the rated input current (FLA) for 0.1 seconds.
Note: The table below is for reference only. All local and national electrical code must be followed.
Note: Wire AWG recommendations came from Table 310-16 of the National Electric Code Handbook (USA).
