Accessories 8.9 Phase barriers Procedure 1. Shorten the phase barriers for the transfer switching equipment sizes 3 and 4 if necessary. 2. Insert the phase barrier into the appropriate mounting channel on the transfer switching equipment. – With 3-pole types, insert 6 phase barriers per side in each case. You will need a total of 12 phase barriers per device.
Accessories 8.10 Terminal cover 8.10 Terminal cover Function Terminal covers are used as touch protection for the MTSE with flat terminal. If additional touch protection is required for the terminals (e.g. IP20 degree of protection from the front), terminal covers can be used instead of phase barriers. Phase barriers and terminal covers cannot be connected simultaneously.
Accessories 8.10 Terminal cover 8.10.1 Installing the terminal covers Requirement Note If bridging bars are used, mount them first. You can find more information in chapter Bridging bars (Page 58). The following steps are necessary for fitting the terminal covers. ●...

ESD guidelines Introduction to ESD Observe the ESD guidelines described in this chapter when handling the 3KC0 transfer switching equipment. Electrostatic sensitive devices (ESD) Electrostatic sensitive devices are destroyed by voltage and energy levels far below the limits of human perception. Voltages of this kind occur as soon as a device or an assembly is touched by a person who is not electrostatically discharged.
