Ambient temperature derating, IP21 (UL Type 1)
In the temperature range +40…50 °C (+104…122 °F), the rated output current is
derated by 1% for every added 1 °C (1.8 °F). The output current can be calculated by
multiplying the current given in the rating table by the derating factor (k, in the
diagram below).
Ambient temperature derating, IP55 (UL Type 12)
IP55 (UL Type 12) drive types, other than the exceptions below
In the temperature range +40…50 °C (+104…122 °F), the rated output current is
derated by 1% for every added 1 °C (1.8 °F). The output current can be calculated by
multiplying the current given in the rating table by the derating factor (k):
IP55 (UL Type 12) drive type -293A-4 and -260A-4
In the temperature range +40…45 °C (+104…113 °F), the rated output current is
derated by 1% for every added 1 °C (1.8 °F). In the temperature range +45…50 °C
(+113…122 °F), the rated output current is derated by 2.5% for every added 1 °C
