factor of the entire run. The length of the run in feet and the power factor of the run

should be used in the following resistance equation to calculate the value on the right

side of the equation.

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 below.

NOTE: All network wiring must consist of two twisted-pairs. One twisted pair is

the +24V conductor and the ground (G) 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.

Rack Mounting

WARNING: To prevent bodily injury when mounting or servicing this unit in a

rack, you must take special precautions to ensure that the system remains stable. The

following guidelines are provided to ensure your safety:

4 The unit should be mounted at the bottom of the rack if it is the only unit in the

rack.

4 When mounting this unit in a partially filled rack, load the rack from the bottom

to the top with the heaviest component at the bottom of the rack.

4 If the rack is provided with stabilizing devices, install the stabilizers before

mounting or servicing the unit in the rack.
