Eaton EMR-3MP0 - Page 187

The optical 󰊎ber is the only method of transmitting temperature data from the URTDII
Module to the protective device.
Preassembled plastic optical 󰊎bers with connectors can be ordered from Eaton, or from
any distributor of Agilent Technologies® optical 󰊎ber products. In addition, these same
distributors o󰊍er long rolls of cable with connectors that can be installed in the 󰊎eld.
Some distributors will make custom lengths to order.
NOTICE!
Force is 11 pounds (50 Newtons).
Surplus length of a pre-cut 󰊎ber does not cause a problems. Simply coil and tie the excess
󰊎ber at a convenient point. Avoid high tie pressure. Bending radius of the 󰊎ber should be
greater than 2 in. (50.8 mm).
The 󰊎ber termination at the URTDII simply snaps into or out of the connector. To connect
the 󰊎ber termination at the protective device, push the plug of the 󰊎ber optic onto the
device interface then turn it until it “snaps”.
CAUTION!
The protective device as well as the URTDII have various power supply options. Make
certain that the power supply is acceptable for both units before connecting the same
power supply to both devices.
