 Leave at least 50mm of space between the wiring ducts of the unit and
other devices to allow heat radiation and unit replacement.
 Do not install the units stacked up, horizontally or upside down. Doing
so will prevent proper cooling of the units and cause overheating inside.

 Do not install the unit above devices which generate heat such as heat-
ers, transformers or large-scale resistors.
 Maintain a minimum of 100mm between devices to avoid adverse ef-
fects from noise and heat when installing a device or panel door to the
front of the unit.
