Installation and Startup 2-3
Electrical Precautions Install the DL5 Slave display conforming to NFPA 70E, Electrical Safety
Requirements for Employee Workplaces. In addition to the NFPA general
guidelines, refer to the following:
Careful cable routing helps minimize electrical noise. Route incoming
power to the module by a separate path from the communication cables.
Do not run communications wiring and power wiring in the same
conduit!
Where communication and wire paths must cross, make their intersection
perpendicular.
Grounding helps limit the effects of noise due to electromagnetic
interference (EMI). To avoid problems caused by EMI, properly ground all
equipment and use shielded cables.
Input Voltage Requirements Before connecting the DL5 Slave to the incoming power, verify that the
power source provides:
Voltage: 12-24 Volts DC
Current: 250 milliamperes at 12V DC (300mA inrush)
125 milliamperes at 24V DC (300mA inrush)
Fusing: External fuses should be used
Important: Power, input and output (I/O) wiring must be in accordance
with Class I, Division 2 wiring methods [Article 501-4(b) of the
National Electrical Code, NFPA70] and in accordance with the
local authority having jurisdiction.
