Covering Caps
2-14
Terminal covering caps are available for the screw terminal modules, to increase the
protection of personnel against hazardous voltages (degree of protection against ac-
cess to dangerous parts) on the terminal modules. The degree of protection is in-
creased from the standard "back of the hand protection" (IP1x)" to „finger protection
(IP2x)".
The terminal covering caps provide an enclosure which securely covers all voltage
carrying components. They are simply snapped onto the terminal module. It must be
noted that all screws on the terminal module must be screws in before snapping the
cover on. The terminal covering cap can simply be removed with a screw driver 6x1
mm.
There are two types of covering caps, as shown in Figure 2-13. Ordering information
is provided in Section 1.1 in the Appendix A.
