> CJX7 Series AC contactor

> Common Work Condition and Installing Condition
The installation site elevation does not surpass example, 90% at 20˚C, It must take the
2000m; mesures on the product occuring dew because
Ambient air temperature should not over of the change of temperature.
+40˚C, also not over +35˚C with in 24h, the The installation site pollution class is 3;
lower limit of ambient air temperature is -5˚C; The contactor can be mounted vertically or
The air relative humidity at installation site horizontally. If vertically mounts, the gradient
should not over 50% when the maximum tem- between the mounted surface and the perpen-
CJX7-63 perature is +40˚C; the higher relative humidity dicular plans is not bigger than= 30%; (See
are allowed under lower temperature, for Fig 1)
