(Note 1) The heating amount is the value for the rated output.
(Note 2) When installed in a sealed state, the guide for the heating amount outside the panel must
be calculated with the following expression.
Heating amount outside panel =
(Max. heating amount described in specifications above – 15) × 0.85
Note that the units marked with a * in the above specifications do not have a fin, so the
heating amount is only for inside the panel.
(Note 3) Due to the structure, heat will easily accumulate in each unit. Thus, install a fan in the power
distribution panel to agitate the heat at the top of the unit. (Velocity 2m/s or more)
CAUTION
The MDS-B-V14L-110 and MDS-B-V14L-150 do not have built-in dynamic
brakes. An external dynamic brake unit must be provided.
Refer to the section 5-6 Dynamic brake unit.
