12-6 Installation Instructions
Power / Parallel Port Wiring The parallel port data inputs and power inputs are wired by means of
pull-off terminal strips. These strips may be removed and wired separately,
and then inserted onto the unit after the unit is mounted in the enclosure.
1. Connect a 12-24 VDC input voltage source to the DL5 power terminals
(TB2).
•
The hot lead of the power source is connected to terminal #2 (12-24
VDC).
•
The common lead of the power source is connected to terminal #1.
2. Connect the communication lines from the host programmable
controller, computer, or other controlling devices to the DL5 parallel or
serial ports.
Note: To ensure proper connection through the pull-off terminals, strain
relief must be provided for all DL5 wiring.
!
ATTENTION: There are no fuses contained in the DL5.
Therefore, we recommend that external fusing be used to avoid
any possible damage to the DL5 or power supply.
!
ATTENTION: You must connect the common lead of the
power source to the DL5. Failure to connect the common lead
may result in electrical shock. In addition, the common lead
protects the DL5 from electrical noise. Do not apply power to
the display until all wiring to the DL5 is completed.
!
ATTENTION: The common for the parallel port should be
the same common as the power source.
