Installing the Bulletin 2705 Keypad Module
This chapter lists electrical precautions and power and grounding
requirements for installing the Bulletin 2705 RediPANEL Keypad Module.
Topics also include selecting NEMA enclosures, the mechanical installation
of the module, and connecting to remote I/O links and to scanner modules.
Install the Bulletin 2705 Keypad Module using publication NFPA
70E,Electrical Safety Requirements for Employee Workplaces. In addition
to the NFPA general guidelines, we have added some specific guidelines.
Do not program any of the function keys on the Keypad
Module as emergency stop switches. Emergency stop
switches must be hard–wired to the master control relay of the
system in order to turn off all machine power completely.
ATTENTION:
!
Careful routing helps cut down on 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 wire paths must cross, make their intersection perpendicular.
With solid state systems, grounding helps to limit the effects of noise due to
electromagnetic interference (EMI). To avoid problems caused by EMI, use
shielded cables.
Before connecting the Keypad Module to the incoming power, verify that the
power source and module type (AC or DC) are in agreement.
The Keypad Module will operate from these sources:
•
90–265 Volts AC, switch selectable, 47–63Hz
•
18–30 Volts DC
