„ Controlling the Ambient Temperature
To enhance the reliability of operation, the VS-656DC5 should be installed in an environ-
ment free from extreme temperature increases. If the VS-656DC5 is installed in an enclosed
environment, such as a box, use a cooling fan or air conditioner to maintain the internal air
temperature below 45
°C.
„ Protecting the VS-656DC5 from Foreign Matter
Place a cover over the VS-656DC5 during installation to shield it from metal powder pro-
duced by drilling.
Always remove the cover from the VS-656DC5 after completing installation. Otherwise,
ventilation will be reduced, causing the VS-656DC5 to overheat.
2.2 Clearances
Install the VS-656DC5 vertically and allow sufficient clearances for effective cooling as
shown in Fig. 3.
