What input voltage and fuse size does the XMT 304 require?

The XMT 304 requires 400V input power and draws 17.0 input amperes at rated output. The maximum recommended standard fuse or circuit breaker rating is 30 amperes, per the 1996 National Electrical Code. Note that actual input voltage should not exceed ±10% of the required input voltage, or output may not be available. (Page 17)
