3.2.1
Summary
Using the worksheet, you can determine the day-to-day power
requirements for your intended system as well as how much battery
power you may require to maintain your system in the absence of external
power. By downloading the Excel spreadsheet from SupportNet, you can
then adjust your expectations and requirements to meet your FB107
power needs.
3.3
Wiring Connections
This section describes how to connect the FB107 to power, I/O devices,
and communication devices. Use the recommendations and procedures
described in this section to avoid damage to equipment.
Note:
Check the input power polarity
before
you apply the power.
The external connections or field terminals are located on the CPU or
optional modules. The terminal block accepts wires up to size 16 to 24
AWG.
Caution
Always turn off the power to the FB107 before you attempt any type of
wiring. Wiring powered equipment could result in personal injury or
property damage.
To avoid circuit damage when working inside the unit, use appropriate
electrostatic discharge precautions, such as wearing a grounded wrist
strap.
I/O wiring requirements are site- and application-dependent. Local, state,
or NEC requirements determine the I/O wiring installation methods.
Direct burial cable, conduit and cable, or overhead cables are options for
I/O wiring installations.
Caution
Failure to exercise proper electrostatic discharge precautions, such as
wearing a grounded wrist strap may reset the processor or damage
electronic components, resulting in interrupted operations.
To connect the wire to the removable block compression terminals:
1.
Strip ¼ inch of insulation from the wire.
2.
Insert the bare end into the clamp beneath the termination screw.
3.
Tighten the screw, taking care not to over-torque it.
Expose a minimum of bare wire to prevent short circuits. Allow some
slack when making connections to prevent strain.
Note
:
Twisted-pair cable is recommended for I/O signal wiring.
