ABB 1912JA001100000 One Year Warranty
Description
Single point grounding of the Type SLC controller provides an analog
and digital DC grounding system free of circulating currents. Jumper
W106 on the power supply board (Fig. 2-3) connects the DC system
common to the AC grounding conductor terminal TB3-2 ( ). Jumper
W106 can be cut and removed to isolate DC system common from
AC ground.
Multiple Controllers If several Type SLC controllers are connected through the module bus
communication link, then the system commons are also connected. For
a single point grounding system, system common must be tied to earth
ground only at one point. Cut and remove jumper W106 (Fig. 2-3) on
the power supply board of all controllers that are to be linked together
via the module bus. Use a separate 14 AWG jumper wire to connect the
DC system common (TB2-1) of each controller to an isolated system
common bus. From one point on the DC system common, use an eight
AWG wire to connect to a dedicated earth ground (Fig. 2-4). This dedicated earth ground should connect to the same grounding point as
the AC safety ground (typically the site grounding grid). There should
be no more than one-ohm resistance between the DC system
grounding conductor and the AC safety conductor.
