I would like to ask everyone: for the 220V UPS circuit in the instrument cabinet of the new installation, the management requires that the neutral wire be grounded, but the design does not specify such a requirement. Is this requirement reasonable?

The HG_T20509-2014 Specification for Instrument Power Supply does not require the neutral wire to be grounded; generally, the negative terminal of a 24V supply is grounded
