Rockwell Automation 2706-F11J_F11JC_F21J_F21JC DL50 INSTALLATION MANUAL - Manual (Page 34)

Chapter 4
Installing the DL50
4–9
Careful wire routing helps cut down on electrical noise. To reduce electrical
noise, the DL50 should be connected to its own branch circuit. (See the next
section for power requirements in the European Union or EFTA regions.)The
input power source should be protected by a fuse or circuit breaker rated at
no more than 15 Amps. Route incoming power to the DL50 by a separate
path from the communication cables.
!
ATTENTION: Do not run signal wiring and power wiring in
the same conduit!
Where power and communications lines must cross, they should cross at
right angles. Communications lines can be installed in the same conduit as
low level DC I/O lines (less than 10 Volts).
All communications lines should be shielded. The shield should be connected
to ground only at the transmitting device.
