The number of LVD Kits used depends on the type of MTS:
• For MTS 2, only one LVD is necessary.
• For MTS 4 with two batteries, two LVD devices have to be used (one LVD for each PSU).
• For MTS 4 powered with a single battery, LVD battery cables should be connected in parallel. LVD
controller cables should be connected to separate PSUs so each PSU controls a LVD.
•
For MTS with XHUB configuration, see the first two points in this list.
