Table 8 – Voltage Ranges (Typical)
The typical voltage range is (+/-) 10 % from rated voltage with the exemption of the 208/230 dual rated **V
models which are -5% +10% (197 min to 253 max voltage)from nominal as shown in the above table. The
following ZS**KAE models are now approved to operate within the full (+/-)10% range with a minimal voltage of
187 and a maximum voltage of 253 (ZS09,11,13,15,19, 21, 26KAE-PFV). The following models are not qualified
to the full (+/-) 10% at this time, ZS29KAE-PFV and ZS33KAE-PFV.
