6. For 4-channel (single-board) relay options,
mount the relay board to the U-brackets as
shown in Figure 3 and secure with two of the
screws provided. Use the remaining two
screws to attach the second protective shield to
the opposite side of the U-bracket.
For 8-channel (two-board) options, mount the
second relay board to the U-brackets in place
of the second protective shield.
7. Reinstall wired connector (J8, or J7 and J8) to
the indicator CPU board.
8. Use cable ties and mounts to secure cabling to
the inside of the indicator enclosure as shown
in Figure 3.
9. Position backplate over the enclosure and
reinstall the backplate screws. Use the torque
pattern shown in Figure 4 to prevent distorting
the backplate gasket. Torque backplate screws
to 10 in-lb (1.13 N-m).
10. Ensure no excess cable is left inside the
enclosure and tighten cord grips. Make cable
connections to external equipment as required.
