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-

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 generator supply (E4). Refer to Figure 2 for 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 3 and 4).

Step 3: The Voltage Selector Plug is shipped in the
600Vac position. Move the Selector Plug to the appropriate 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 normal and load terminals. Check all phases on a threephase 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 generator 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 feature 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 seconds.
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.
The following lights should be ON:
● Source 1 Available
● Source 1 Connected
● Source 2 Available

Transfer Switch
Quick Start Instructions
This Transfer Switch may be equipped with a two position 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 normally when the Source 1/Source 2 Selector Switch is

Effective: June 2003 Page 5 used (Figure 8 and 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 8 and Figure 9). The
Transfer Switch will move to the position indicated by the Source 1/Source 2 Selector Switch.
