Note:
Note: If the system has a power failure transfer (PFT) unit that uses ground start trunks,
you must install a temporary ground wire to the PFT units. This action allows the
units to operate correctly when the cabinet is turned off. The AUX cable, that
usually supplies the ground, will be disconnected.
2. Connect a 10 AWG (#25) (2.6 mm
2
) wire to pin 49 of the connecting block that is associated
with the PFT panel.
3. Route the opposite end of the wire to an approved ground and connect the wire to the
ground.
