When using MDS-C1-CV-185, MDS-C1-SPA[]-185[]
Total heating value = (33+162) + (62+280)
= 537 [W]
Heating value in panel = (33) + (62)
= 95 [W]

1-2-6 Heat radiation countermeasures
In order to secure reliability and life, design the temperature in the panel so that the ambient
temperature of each unit is 55°C or less.
If heat accumulates at the top of the unit, etc., install a fan so that the temperature in the panel remains
constant.
(Note) Due to the structure, heat easily accumulates at the
top of the unit. Install a fan in the power distribution
panel to circulate the heat at the top of the unit.
