3.4 Preparing for Power/Signal Connection
Reference Drawings:
Shop Drawings ......................................................... Refer to Appendix A
If the display needs openings for the power
and signal, punch out the knockouts in the
lower right corner from the rear. Refer to the
Shop Drawing for your display.
Figure 15: Opening the Display for Power and Signal
1. With a 7/32" nutdriver, apply
pressure to latch and turn it a
quarter-turn counter-clockwise. The
module door will swing open to the
left.
2. Route power to the display through
a fused disconnect switch capable of
opening all ungrounded power
conductors. Locate this disconnect
within the line of sight of any
personnel performing maintenance
on the display. If the disconnect is
located out of sight of the display, it
must be capable of being locked in
the open position.
3. Power conductors from the disconnect to the display must route through
conduit in agreement with local codes.
4. You may also route the signal cable from the control computer to the
display at this time.
Be sure to run the power and signal cables in
separate conduit.
