AV2 & PRO2
Resistance Equation
R = Resistance (refer to table below).
L = Length of run (or chain) in feet.
PF = Power factor of entire run (or chain).
R < L x PF
40,000
Where:
The required wire gauge should be chosen such that the resistance value is less than
the value calculated in the resistance equation. Refer to the table after this paragraph.

NOTE:
All network wiring must consist of two twisted-pairs. One twisted pair is
the +24V conductor and the GND conductor and the other twisted pair is the Y
conductor and the Z conductor.
NOTE:
When daisy chaining network units, always twist the ends of the incoming
wire and outgoing wire which share a pin on the network connector. After twisting
the ends, tin the twisted connection with solder. Apply solder only to the ends of the
twisted wires. Avoid tinning too far up or the tinned end becomes brittle and breaks.
After tinning the twisted ends, insert the tinned connection into the network
connector and tighten the retaining screw. Repeat the procedure for the other three
network conductors.
Hardware Hookup
Refer to the hookup diagram on the next page and aside from attaching power last,
complete the connections in any order. Refer to "Network Wiring" on page 14 when
making network connections.
NOTE:
To prevent overheating, do not operate this product in an area that exceeds
the environmental temperature range listed in the table of leading specifications.
Consideration must be given if installed in a closed or multi-unit rack assembly since
the operating ambient temperature of the rack environment may be greater than the
room ambient. Contact with thermal insulating materials should be avoided on all
sides of the unit.
NOTE:
The maximum continuous current from equipment under any external load
conditions shall not exceed a current limit that is suitable for the minimum wire
gauge used in interconnecting cables. The ratings on the connecting unit's supply
input should be considered to prevent overloading the wiring.
NOTE:
Since the plug on the power supply cord is used to disconnect power from
the unit, the socket-outlet shall be installed near the equipment and shall be easily
accessible.
