5.4.2 Liebert® IntelliSlot™ Relay Card Jumper Setup
The Liebert® IntelliSlot
™
Relay Card has five jumpers, P3 through P7, as shown in Figure 32. Each
jumper connects two pins.
Figure 32 Jumper location and numbering
By default all five jumpers have shunts installed. The two pins are shunted together to provide the
functions shown in Table 11, allowing relay commons to be tied together.
The jumpers should be removed if there is any external voltage source that may intentionally or
inadvertently be connected to the relay.
Removing the shunt from any two pins breaks the connection between the relay commons so
they are not tied together.
