WARNING!
Do not use the Battery Backup/LVD option “BAT” terminal on
units connected in parallel, as there is a risk that the potential
load current could be higher than the rating of the internal low
voltage disconnect relay.
Otherwise damage to the unit, load, and/or personal injury may
occur if the battery output current through the “BAT” terminal
exceeds the rating for an individual supply.
(Figure: 4 Back Panel Parallel Connections)
1. After configuring each power supply for parallel operation, turn the
Power Switch on all units to the OFF position.
2. Connect the positive terminals (labeled “POS”) of each unit together at
a common positive load point using the optional ICT-PAR parallel
straps. This will provide optimal current sharing between the units. See
figure 4.
3. Connect the negative terminals (labeled “NEG”) of each unit together at
a common negative load point using the other ICT-PAR parallel strap.
4. Using a RJ11 4-wire straight-though cable (Optional accessory part no.
ICT-JMP), connect the SHARE “A” terminal on the first unit to the
SHARE “B” terminal on the second unit. If there will be more than two
units operating in parallel, repeat this step for each unit, as shown in
Figure 4 above.
