4.3.1 Paralleling Cable Kit
Module-to-module communication cables are required for 1+N parallel systems. A kit with RJ-45
connectors ships with each multi-module EXL S1 UPS. At least one kit is required for each added UPS
module; the number of kits required is one fewer than the number of UPS modules in the 1+N system (for
example, six UPS modules would require five kits).
NOTE: Verify appropriate strain relief for all parallel communication cables to ensure no tension or
pressure on the RJ-45 to AP30-XP71 and AP30-XP72 connections.
Parallel communication cables must be selected from one of the suppliers to be compatible with the RJ-45
connector on the EXL S1. Vertiv Part # 564556P1 supplied or ordered with multi-module systems. Contact
factory for details. Approved CAT6 cable suppliers:
• ABA, Part #TSR2404N70GY
• Belden, Part #7953A
• Comtron Cable LLC, Part #CAT 6 Plenum F/UTP
• Primus, Part #CAT 6 FTP
4.3.2 Multi-Bus Synch Module (MBSM)
This module is available to support six or up to 11 UPS modules, and is generally configured to synchronize
all modules to a reference bus (e.g., bypass line). See the manual for this module for more details.
