Mechanical Configuration of an Automation System with SIMATIC S7 Ex Modules 1-10 If you maintain these minimum spacing dimensions then: you will guarantee heat dissipation of the S7-300 modules you will have sufficient space to insert and remove the S7-300 modules you will have sufficient space for installing lines Note If you use a shield support element, the specified dimensions apply as from the lower edge of the shield support element. The L+/M lines on the Ex modules can be wired directly or via connection elements. For direct wiring, route the L+/M lines from the cable duct (if a line chamber is used, see Section 1.2 ) directly to the terminals of the module front connector. You can route the Ex process lines directly from the front connector to the items of apparatus. You can use commercially available clamp-type distributors for wiring via connection elements. You then have the option of disconnecting the L+/M supply lines module by module by means of a plug connector (see Fig. 1-6).
