MDS-D-SVJ3/SPJ3 Series Instruction Manual
1-4 Installation of the drive unit
1-4-2 Installation direction and clearance
Wire each unit in consideration of the maintainability and the heat dissipation, as well as secure sufficient
space for ventilation.
Installation clearance
- For the heat radiation, secure the following dimensions around the unit.
- Secure the distance shown below for clearance between the unit side face and the device which is a
noise source of power wire or relay, etc.,.
- Secure clearance for installing the unit so that the connector can be inserted or pull out.
(1) Installation of one drive unit
(2) Installation of two or more drive units
Leave a large clearance between the top of the drive unit and the internal surface of the control box, and
install a fan to prevent the internal temperature of the control box from exceeding the environmental
conditions.
1. The ambient temperature condition for the drive units is 55°C or less.
2. Because heat can easily accumulate in the upper portion of the units, give sufficient consideration
to heat dissipation when designing the panel. If required, install a fan in the panel to agitate the
heat in the upper portion of the units.
