NOTE: For branch circuits over 50 amps, only listed Siemens or Murray circuit breakers shall be used. Transfer Switch Data Decal A data decal is permanently affixed to the transfer switch enclosure.
Installation Section 3: Installation Introduction to Installation Connecting Power Source and Load Lines This equipment has been tested at the factory. Installing the switch includes the following procedures: • Mounting the enclosure. • Installing the circuit breakers. • Connecting power source and load leads. • Connecting the generator control wiring. • Connecting branch circuit wiring. Mounting Mounting dimensions for the transfer switch enclosure are in this manual.
Installation 6. Connect utility (normal) and generator ground cables to ground connection and neutral cables to the neutral bar. 7. Customer LOAD leads are not pre-wired at the factory. 8. Neutral and Ground Bars Accept #4-#14 AWG Cu/ Al cable. If a larger Neutral or Ground Cable is required for the Generator Connection, Please utilize Lug Kit Siemens ECLK2 or Generac part number 10000006293 which accepts #4-2/O Cu/Al cable. Replace with Littlefuse® 021606.3MXHP, Optifuse® FCD-6.
Installation Installing Branch Circuit Conductors – USA Installations 1. Select which branch circuits will be protected by the generator in the normal power panel board. 2. Turn the circuit breaker in the normal power panel board to the off position. 3. Remove the ungrounded (hot) conductor from the circuit breaker and neutral conductor from the neutral terminal bar in the normal power panel board.
Installation Auxiliary Contact Fault Current Label See Figure 3-3. If desired, there is one normally-closed Auxiliary Contact (A) on the transfer switch to operate customer accessories, remote advisory lights, or remote annunciator devices. A suitable power source must be connected to the common terminal. If needed, an extra auxiliary contact can be added. A See Figure 3-4.
Operation Section 4: Operation Functional Tests and Adjustments Following transfer switch installation and interconnection, inspect the entire installation carefully. A competent, qualified electrician should inspect it. The installation should comply strictly with all applicable codes, standards, and regulations. When absolutely certain the installation is proper and correct, complete a functional test of the system. CAUTION Equipment damage.
Operation Return to Utility Source Side . Frequency 60-62 Hz 1. Manually actuate switch to return manual operating handle to the UP position. Terminals E1 to E2 240-246 VAC Remove manual operating handle from movable contact carrier arm. Return handle to storage bracket. Terminals E1 to NEUTRAL 120-123 VAC 2. Terminals E2 to NEUTRAL 120-123 VAC 5.
Operation Move the main switch contacts back to the utility position. 8. NOTE: See Manual Operation. Handle and operating lever of transfer switch should be UP. 9.
