3-8 Power Connections Revised August-2017
3.6 Wiring Connections
The following paragraphs describe how to connect the FB100 to power,
I/O devices, and communications devices. Use the recommendations
and procedures described in the following paragraphs to avoid damage
to equipment.
Note: Check the input power polarity before turning on the power.
The external connections or field terminals are all located on the
termination board. The terminal block accepts wires up to 16 AWG in
size.
Always turn off the power to the FB100 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.
3.6.1 Wiring Connections
The connectors on the FB100 Termination module use compression
terminals. The input power termination (CHG+ / CHG-) uses a
removable connector and accommodates wiring up to 16 AWG in size.
In all cases, make connections by baring the end (¼ inch maximum) of
the wire, inserting the bared end into the clamp beneath the termination
screw, and then tightening the screw to 0.25 N-m (2.2 lb-in.).
Note: Do not over torque the connector screws.
The inserted wires should have a minimum of bare wire exposed to
prevent short circuits. Allow some slack when making connections to
prevent strain.
3.6.2 Connecting Enclosure Ground Wiring
The FB100 and related components use the National Electrical Code
(NEC) that governs the ground wiring requirements.
Two ground screws are located inside the back of the enclosure. It is
recommended that a minimum of 14 AWG wire be used for the
ground wiring.
