Screw Terminal Connectors
The next step is to connect the screw terminal connectors. The screw terminals
accept 0.22mm – 3.3mm (22 – 12AWG) gauge solid wire. The optimum
tightening torque for the screw terminals is 0.75 Newton-meters (6 lbs.(f)- in.)
maximum. The ideal flathead screwdriver tip width for use with the screw
terminal connectors is 3mm (0.12”). Wires should be stripped to a length of 7mm
(0.28”). It may be useful to use a soldering iron to tin the stripped lengths of any
stranded wires to prevent fraying and inadvertent contact with adjacent
terminals, although this is not required.
The screw terminal connectors can be divided into seven groups, as listed below.
These are described in detail in the following sections.
•
High Voltage Mains Power
• LONWORKS Network
• Dry Contact Relay Outputs
• Pulse Meter Inputs
• Digital Inputs
• LONWORKS Network
• +12V < 20mA Output
When reviewing these sections, it is important to remember that you must wire
the mains power screw terminal connectors in order to supply power to the
i .LON
100 server. In addition, if you are using a TP-FT/10 model pair (Models 72101
and 72102)
i .LON 100 server, you must connect the LONWORKS network screw
terminal connectors to a L
ONWORKS TP/FT-10 channel in order to access a
network with the
i .LON 100 server. All other screw terminal connectors are used
for optional features.

Safety Warning
When connecting a unit, always connect earth ground first, then Neutral, and
then Line. This minimizes the risk of shock or damage should power
inadvertently be present on Line.
