Chapter 2 Installation CFP2000 2-1 Mounting Clearance Prevent fiber particles, scraps of paper, shredded wood, sawdust, metal particles, etc. from adhering to the heat sink Install the AC motor drive in a metal cabinet (IP41 models). When installing one drive below another one, use a metal separation between the AC motor drives to prevent mutual heating and to prevent the risk of fire accident. Install the AC motor drive in Pollution Degree 2 environments only: Normally only nonconductive pollution occurs and temporary conductivity caused by condensation is expected. The appearances shown in the following figures are for reference only. The actual motor drives may look different.
2-2 Airflow direction: (Blue arrow) Inflow (Red arrow) Outflow (Black) Distance Single drive installation (Frame A–D) Side-by-side horizontal installation (Frame A–D) Figure 2-1 Figure 2-2 Multiple drives side-by-side vertical installation (Frame A–D) Ta: Frame A–D When installing one AC motor drive below another one (top-bottom installation), use a metal separation between the drives to prevent mutual heating. The temperature measured at the fan’s inflow side must be lower than the temperature measured at the operation side. If the fan’s inflow temperature is higher, use a thicker or larger size of metal separator.
Operation temperature is the temperature measured at 50 mm away from the fan’s inflow side. (As shown in the figure below) Ta=50ºC Figure 2-3
