4.2 Grounded Power Feeds
Where the return side of a site-supplied power feed is grounded, provision is made on all versions of the
lightning arrestor units to link the return feed to the integral grounding lug on the unit. A shorting link is
stored on J4. When grounding is required, this is transferred to J5 (see Figure 4-6).
Figure 4-6 Grounded Power Return Link
On earlier models of both the indoor and outdoor lightning arrestors, the shorting link feature is not
present. To ground the return side of the power supply for the earlier models, connect a shorting wire
between the “RTN” connection on the power connection block and the grounding point on the PCB as
shown in Figure 4-7.
