Installation
The following types of installation are permissible for contactors and auxil-
iary contactors in ambient temperatures of up to 70 °C:
Frame size S00: installation in series
Frame sizes S0 to S3: The resistor block must be installed on the right next
to the contactor because of the connecting leads there.
Dimensions
When the resistor is mounted, the contactors of frame sizes S0 to S3
become wider (see Section 3.6, Dimensioned drawings).
