The jacket and shielding of the cable should be stripped back to permit the seal to form around the
individual wires. This will prevent air particles and water leakage through the inside of the shield
and into the enclosure
·
It is recommended that explosionproof drains and conduit breathers be used. In some applications,
changes in temperature and barometric pressure can cause breathing which allows moist air to
enter and circulate inside the conduit. Joints in the conduit system are seldom tight enough to
prevent this breathing
2.4.8 Analog output, isolated supply, non-isolated supply and jumper
configuration
The analog output may be powered from the main instrument power supply or a separate,
independent power supply in which case an isolated wiring configuration is necessary.
To set a Non-isolated or Isolated current output, simply move the Jumpers/shorting jacks (JP3 and JP4)
to either the non-isolated or isolated current position. For non-isolated current output, ensure pins 3 &
2 at JP3 & JP4 location on the main terminal board are jumped (shorted). Factory standard models ship
with jumpers at JP3 & JP4 in the non-isolated current output position.
For Isolated current output, pins 1 & 2 at JP3 & JP4 should be jumped (shorted). Note that JP3 is for
configuring channel 1 and JP4 is for configuring channel 2. Jumpers and pins are located next to the
power and 4-20 output terminals on the main terminal board. See
