Terminals of the SPM have two-wire connection (L1 and N) and ground terminals. The upper
ground terminal is for a load cable and the lower ground terminal is for UPSs. The wiring shall
be done according to the following wiring diagrams. The terminals and cable routing is shown
in Figure Cable routing of the SPM. See also Table 14 for cable and fuse ratings for the different
UPS ratings.
