THIS INSTRUCTION IS NOT A COMPLETE SOURCE
OF INFORMATION ON THE TRANSFER EQUIP-
MENT. INSTALLATION SHOULD NOT BE STARTED
UNTIL THE ENTIRE INSTRUCTION BOOK HAS
BEEN REVIEWED AND UNDERSTOOD. FAILURE TO
FOLLOW INSTRUCTIONS CAN RESULT IN DEATH,
SEVERE PERSONAL INJURY, OR PROPERTY
DAMAGE.
Step 1: Mount the transfer switch on a flat rigid surface
(Figure 1). Shim if necessary. For seismic mounting
requirements, check the instruction book.

Step 2: Install power cables. Cables shall be sized and
installed per National Electrical Code, refer to NFPA70.
The cable must be sized within the specified cable size
range on the side of the cable connectors.
Connect cables and torque to correct value indicated on
the label near the lugs in the following order: [1] Load
Cables*(T1, T2, T3), [2] Normal or Utility Supply (N1,
N2, N3), [3] Emergency and Generator Supply (E1, E2,
E3). For 4 pole transfer switches, connect load cables
(T4), normal or utility supply (N4), and emergency or
generator supply (E4). Refer to Figure 2for the location
of all parts discussed in this document.
* Load cables on switches using the vertical design MUST be
connected and torqued BEFORE installing the SUPPLY
cables (Figures 3and 4).

Step 3: Turn generator OFF at the Generator Control
Panel. This will prevent unexpected activation of the
generator.
Step 4: Connect Engine Generator Control to
Terminals 51, and 52 (Red) (Figure 5). This contact is
CLOSED whenever the engine generator is needed,
and should be connected to a generator controller.
NEVER connect directly to a starter solenoid or ignition
system.

Step 5: Apply Utility (Normal) Power. If the switch is
properly applied for the system voltage ordered, the dis-
play should work and the Normal Source (Source 1)
Available LED should light (Figure 6). Using a voltmeter,
check for proper system voltage on the normal and load
terminals. Check all phases on a three-phase switch.
Voltage measurements should be taken phase to phase
and phase to neutral.

Step 7: To change or add a setpoint, place the <Run -
Program> switch on the rear of the IQ Transfer Logic
unit in the Program position (Figure 7). The red LED
next to Program on the front display will flash (Figure 6).
Figure 7 IQ Transfer Logic (Rear View)
Press the <Display Select> pushbutton until the Set
Points LED lights. Use the <Step> pushbutton to step
through the setpoints.
Use the <Increase> and <Decrease> pushbuttons to
change the setpoint.
When finished changing setpoints, return the <Run-
Program> switch to the Run position and wait. The dis-
play should display the word Program and the red LED
next to Program will go out. When the display goes
blank, the setpoints have been changed to their new
values.

Step 8: Manually start the engine generator at the gen-
erator controller (Figure 8). With the generator running,
check that the Emergency Source (Source 2) Available
LED is lit. Press the <Display Select> pushbutton to
display the voltage and frequency on Source 2. Then
using the <Step> pushbutton, step through the phase
voltages, frequency and message display. If the source
message indicates that the source is Good, shut down
the generator and place the genset controller in the
Auto operating position. If the message indicates a
problem with the source, the setpoints should be
reviewed, and the generator checked for proper voltage
and frequency output.
Step 9: Initiate a Load Test from the front panel of the
IQ Transfer (Figure 9). This may be done by making the
TMODE setpoint 1 and pressing the <Engine Test>
pushbutton. The generator should start, the ATS should
transfer and run on the generator for the set test inter-
val, then proceed to a TDEN countdown and return to
NORMAL. While the tansfer switch is connected to
emergency, use a voltmeter to check for correct system
voltage on the load terminals of the transfer switch.
Check all phases on a three-phase system. Voltage
measurements should be taken phase to phase and
phase to neutral. A load test will cause a momentary
power outage during transfer.

Generator Running) Figure 9 IQ Transfer Logic (During Test)

Step 10: ATHI/ATVI Power Failure Test - Initiate a Load
Test by simulating an actual power failure.
(1) This should be done by opening the upstream
breaker or fused disconnect switch.
(2) If the ATS is Service Equipment Rated with no
upstream disconnect, use the Normal Control Circuit
Disconnect to simulate a power failure (Figure 10).
This can be found in one of two places. The first
would be located directly beside the normal breaker.
The second would be located on the transformer
panel/customer connection panel. The normal con-
trol circuit disconnect is the disconnect marked
Normal. The disconnect switch should be in the ON
position for normal operation. Turning the switch to
the OFF position will simulate a normal power out-
age.
Figure 10 Control Disconnect
(3) The generator should start and the ATS should
transfer to Emergency.
(4) After transfer, close the upstream breaker, or
close the Normal Control Circuit Disconnect. The
TDEN timer should begin counting, and, when com-
plete, the ATS should transfer to Normal. The En-
gine Cooldown Timer should time out and shut the
emergency power unit down.
NOTICE
While performing testing, if an undesired or undoc-
umented result occurs, first contact the local
Genset dealer. If the result is not corrected, contact
the Cutler-Hammer Product Integrity Center at
