1: GENERAL DESCRIPTION 1:1 Switchgear: The OPT2400 transfer switch mechanism consists of a basic mechanical switching assembly that can be configured to satisfy various application requirements. This manual describes the following models: OPT2400-2-120/240V-E OPT2400-3-208/240V-E OPT2400-3-480V-E OPT2400-3-600V-E 1:1:1 Specifications for OPT2400 models Please refer to the following Optimal Series Automatic Transfer Switch rating label located on switch for proper ratings associated with your specific model.
1:1:2 Operation: The OPT2400 includes the suitable sensing circuitry for automatic transfer of an electrical load to a stand-by power supply in the event of a drop or loss of voltage of any or all phases of the normal power supply. Upon the restoration of the normal supply, the electrical load is automatically re-transferred to the normal power supply.
1:2 Relay Board Module: The relay board provides means for automatic transfer of a utility source of power to an emergency source of power, upon loss of the utility, and switches back again, upon restoration of the utility. The relay board has no built in delays for transfer. Any required delays must come from an external source (ie.
1:2:2 System Operation: WARNING: THE RELAY BOARD IS FACTORY SET FOR 12VDC APPLICATIONS. IF INSTALLING IN A 24VDC SYSTEM, TWO JUMPERS NEED TO BE CUT. The relay board module has provisions for 12 and 24 VDC operation. The relay board comes factory set for 12 VDC applications.
All electrical wiring connections have a recommended tightening torque. The following chart shows the required electrical tightening torque to allow safe operation. Wiring Connections Connector Mounting aluminum/copper Screws 300 IN-LBS 132 IN-LBS Wire size range 3/0 to 500MCM copper and 4/0 to 500MM aluminum. 2:3 Open Type Transfer Switches: Open type options allow transfer switches to be shipped with no enclosures.
For models OPT2400-3-480V and OPT2400-3-600V 1. The minimum spacing requirements per UL-1008 must not be less than 3/8” through air and 1/2" over the surface of the insulating material. These measures must exist between any uninsulated live part and another uninsulated live part of opposite polarity, uninsulated grounded part other tan the enclosure or any exposed metal part.

3:1 MAIN SWITCH REMOVAL AND REPLACEMENT WARNING: When replacing any parts of the mechanism, isolate the transfer switch from all possible sources of power. To remove the main normal or emergency switches, first electrically isolate the transfer switch from all power sources. a) Disconnect all cables and wiring from the switch terminals.
3:2 MOTOR REMOVAL AND REPLACEMENT WARNING: When replacing any parts of the mechanism, isolate the transfer switch from all possible sources of power. – Electrically isolate the transfer switch from all power sources. – Remove the top support as in section 3:1 steps a, b and c above . –...
5: RECOMMENDED MAINTENANCE WARNING: When performing any maintenance of the mechanism, isolate the transfer switch from any possible source of power. The OPT2400 transfer switch assembly has been designed to require minimum attention under all environmental conditions normally encountered. All sliding and bearing surfaces have a thin coating of grease applied at the factory.
7: ENGINE EXERCISER Introduction The functions of the exerciser time clock are shown in the diagram below. The time clock has two slide switches with three positions: The switch in the upper right corner is a SET SWITCH used to set the present time and day for your locality, run the program, change an existing exercise cycle or start a new program.
Page 21
Programming the Exerciser Time Clock The mode switch slider is in the O or "disable" position when packaged at the factory. The set switch is in the "run" position. Use the following steps to program the exerciser time clock for a particular exercise day, time, and duration: Move MODE SWITCH to "auto"...

Press the PROGRAM button once more to set the day and time for ending the exercise. A default time AM 12:00 appears in the display. A small 2 appears to the right of the time. The lamp symbol is absent. The 2 (or even number) indicates the end of an exercise or open contacts.
