iDryrInverter Inspection and Installation
Introduction
Use this sheet to inspect and connect a replacement iDry inverter assembly.
The inverter should always be inspected before being installed to make sure
all wiring is connected properly and securely.
Safety
Qualified Personnel
Equipment owners are responsible for making sure that Nordson equipment
is installed, operated, and serviced by qualified personnel.
Qualified personnel are those employees or contractors that
Shave experience operating and maintaining high-power and high-voltage
electrical equipment.
Scan safely perform their assigned tasks.
Sare familiar with all relevant safety rules and regulations and are
physically capable of performing their assigned tasks.
WARNING: The control enclosure and coil tray contain high voltages and
high power levels. Failure to ensure and employ all appropriate safety
measures may result in serious injury or death.
WARNING: HIGH VOLTAGE! Disconnect and lockout all power to the
system before perfoming any of the procedures in this section. Electrical
repairs should always be done by a qualified electrician with knowledge of
high voltage systems. Failure to observe this warning may result in fatal
injury to personnel.
WARNING: Never disarm any diagnostic device including but not limited to
the current sensor, overtemperature switches, air pressure switch, or coil
tray lid safety switches. Disarming diagnostic devices will void the warranty
and may cause equipment failure.

Unpacking
The inverter assembly is shipped up-side down in the box, bolted to a wood
panel and secured with a custom foam insert. Loose cables are looped and
secured to the assembly.
1. Open the box, then open the anti-static bag without cutting it, and lift the
wood panel and inverter assembly straight up and out of the box.
2. Remove the bag from the inverter assembly and place it right-side up on
a clean workbench. Remove the screws, lock washers, and flat washers
securing the inverter assembly to the wood panel.
3. Save all of the shipping materials and box to re-use if shipping a failed
inverter assembly back to Nordson Corporation.
Contact Nordson Customer Support at (800) 433−9319 for information on
returns and shipping.
Inspection
Inspect the inverter assembly for loose connections or damage before
installing it into the induction dryer.
1. See Figure 1. Check the indicated harness connectors at Q1, Q2, Q3,
and Q4 and the circuit board. Make sure they are connected properly
and securely according to the labeling on the IGBT Driver board, IGBT
Equalizer boards, and heatsink.
Q1 to J9 and J10 Q2 to J3 and J4
Q3 to J5 and J6 Q4 to J7 and J8
CAUTION: If the harness terminals are disconnected from Q1, Q2, Q3, and
Q4, do not touch the blade-type terminals. Skin oils and other contaminants
can affect the quality of the connection and lead to component failure.
2. See Figure 2. Cut the cable ties securing the two coiled cables and
three coiled harnesses to the inverter.
3. Check the harness connections to T1, TS1, and SC1.

WARNING: Turn off and lock out power at the plant disconnect to the iDry
Induction Dryer before opening the enclosure base doors. The dryer
internal disconnect does not remove all power to the unit. Wait 10 minutes
for the dryer’s internal capacitors to discharge. Failure to observe this
warning could result in personal injury or death.
NOTE: Remove the rear panel from the base to acess the inverter
assembly. Open the front doors to access the distribution board.
1. Turn off electrical power to the system at the plant disconnect and lock it
out. Wait 10 minutes for the dryer’s internal capacitors to discharge.
2. Open the back panel and verify that incoming power has been removed.
Turning off the front panel disconnect does not remove all power from
the system.
3. See Figure 2. At the inverter assembly terminal block TBM, disconnect
the coil tank capacitor cables 409, 410, and GND.
4. See Figure 3. Label and disconnect the two fiber-optic cables (A1, A2)
from the inverter assembly driver board. The cables are grey and blue,
and are polarity sensitive.
5. Disconnect the blue and white twisted pair 15V power cable from the
inverter assembly driver board terminal J11.
6. See Figure 4. Label and disconnect the cables and harness from the
following components:
SCable 407 at PCB8 (−), cable 408 at PCB9 (+).

Inverter Replacement (contd)
8. Remove the fasteners securing the inverter assembly from the
enclosure. Save the fasteners for use with the new inverter.
9. Install the new inverter assembly and secure it in place with the
fasteners removed in step 8.
10. See Figure 3. Connect the blue and grey fiber-optic cables to the new
inverter assembly. Push the connectors into the receptacles until they
click.
NOTE: If you connect the fiber-optic cables incorrectly you will get an
Out of Lock fault. Reverse the cables to clear the fault.
11. Connect the blue and white twisted pair 15V power cable to the inverter
assembly driver board terminal J11.
12. See Figure 2. Connect the coil tank capacitor cables 409, 410, and
GND to the terminal block (TBM) on the inverter board. Make sure you
do not connect either the 409 or 410 cables to the ground terminal.
13. See Figure 4. Connect cable 407 to PCB8 (−) and cable 408 to
PCB9 (+).
14. Connect the inverter assembly harnesses to the Distribution Board
terminal block J5 as described in the table on page 4, step 6.
15. See Figure 1. Connect the system ground wire (heavy green and yellow
wire) to the ground screw at the corner of the heat sink.
16. Install the rear panel on the base. Make sure to connect the panel
ground wire to the base.
17. See Figure 5. If shipping the old inverter assembly back to Nordson
Corporation:
a. Secure the assembly to the wood panel (1) with the shipping screws,
flat washers, and lock washers (2, 3, 4).
b. Pull the anti-static bag (5) over the assembly.
c. Turn the inverter assembly upside down and place it into the custom
foam insert (6) in the shipping box.
d. Close the anti-static bag and tape the opening shut. If removed,
place the bag of silica gel dessicant (7) in the box.
