THIS INSTRUCTION LEAFLET IS NOT A COMPLETE
SOURCE OF INFORMATION ON THE TRANSFER
EQUIPMENT. INSTALLATION SHOULD NOT BE
STARTED UNTIL THE ENTIRE INSTRUCTION BOOK
HAS BEEN REVIEWED AND UNDERSTOOD. FAIL-
URE TO FOLLOW INSTRUCTIONS CAN RESULT IN
DEATH, SEVERE PERSONAL INJURY OR PROPER-
TY 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] Source 1 or Utility Supply (N1,
N2, N3), [3] Source 2 or Generator Supply (E1, E2, E3).
For 4 pole transfer switches, connect load cables (T4),
Source 1 or utility supply (N4), and Source 2 or genera-
tor 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: The Voltage Selector Plug is shipped in the
600Vac position. Move the Selector Plug to the appro-
priate position prior to energizing the switch. Make sure
the selector switch, on the Device Panel, is in the
“Source 1” position. Apply Utility (Source 1) Power. If
the switch is properly applied for the system voltage
selected, the
“Source 1” Available Light,
and
“Source 1”
Connected Light
should illuminate (Figure 5). Using a
voltmeter, check for proper system voltage on the nor-
mal and load terminals. Check all phases on a three-
phase switch. Voltage measurements should be taken
phase to phase and phase to neutral.

The following lights must be ON:
● Source 1 Available
● Source 1 Connected
Step 4: Manually start the engine generator at the gen-
erator controller. Check that the
Source 2 Available
light is lit (Figure 6). Check all Voltages phase to phase
and phase to neutral.
Note: The transfer switch is equipped with a time
delay feature when in the Neutral position. This fea-
ture provides a delayed transition transfer mode for
an Open Transition Transfer Switch. Often used in
systems with inductive loads, a delayed transition
transfer switch may prevent or reduce excessive
inrush currents due to out of phase switching of
loads. This switch provides a time delay in the
Neutral position during the transfer and re-transfer
operations in which both Source 1 and Source 2 are
disconnected from the load circuit. The time delay
is adjustable and is the same for both transfer and
re-transfer operations. The range is from 3-60 sec-
onds.
Step 5: Move the Selector Switch, on the Device Panel,
to Source 2 (Figure 7). The Transfer Switch will move
to the Neutral Position, delay, and then move to the
Source 2 position. Check the
Source 1 Connected
light
and make sure it is extinguished. Check that the
Source 2 Connected
light is illuminated. Return the
Selector Switch to Source 1. Make sure the Transfer
Switch returns to
Source 1
and the
Source 1 Connected
light illuminates (Figure 6). Shut down the Generator
after the manufacturer’s recommended cool down time.

This Transfer Switch may be equipped with a two posi-
tion Keyed Selector Switch that may be used as a
“Service Disconnect” (Figure 8) or as a “Disconnect”
(Figure 9). If this Transfer Switch does have the two
position Keyed Selector Switch, refer to IL01602002E
for proper labeling.
Operation of the Two Position Keyed Selector
Switch:
Operation 1: When the keyed Selector Switch is in the
“Energize” position, the Transfer Switch functions nor-
mally when the Source 1/Source 2 Selector Switch is
used (Figure 8and Figure 9).
Operation 2: To disconnect power from the Load: Turn
the Keyed Selector Switch to the “Disconnect” position
(Figure 10 and Figure 11), then remove the key. The
Transfer Switch will move to the neutral position and
remain there until the Keyed Selector Switch is returned
to the “Energized” position.
Operation 3: To reconnect power to the Load: Reinsert
the key and turn the Keyed Selector Switch to the
“Energize” position (Figure 8and Figure 9). The
Transfer Switch will move to the position indicated by
the Source 1/Source 2 Selector Switch.
