Safety Section 1 Safety 1.1 — General Read the following information carefully before attempting to install, operate or service this equipment. Also read the instructions and information on tags, decals, and labels that may be affixed to the transfer switch. Replace any decal or label that is no longer legible. These safety warnings cannot eliminate the hazards that they indicate.
Safety • Keep the transfer switch enclosure door closed and bolted at all times. Only qualified personnel should be permitted access to the switch interior. • In case of an accident caused by electric shock, immediately shut down the source of electrical power. If this is not possible, attempt to free the victim from the live conductor but AVOID DIRECT CONTACT WITH THE VICTIM. Use a nonconducting implement, such as a dry rope or board, to free the victim from the live conductor.
General Information Section 2 General Information 2.1 — Introduction Thank you for purchasing a Generac transfer switch. This manual has been prepared especially for the purpose of familiarizing personnel with the design, application, installation, operation and servicing of the applicable equipment. Read this manual carefully and comply with all instructions.
General Information 2.3.2— Utility Service Circuit Breaker (if equipped) The utility service and generator disconnect circuit breakers for 100 amp models are: • • • • • Type BQ, 2-pole 120/240VAC, 100A 50/60 Hertz Wire range: #1 - #8 AWG (Cu/Al) The conductor tightening torque is 50 in-lbs. (5.6 Nm).
General Information Four LEDs, located on the Smart A/C Module (B in Figure 2-2), illuminate when a load is connected and powered. The Smart A/C Module has a test button used to simulate an overload condition. This button operates even when the transfer signal is inactive. 0 GROUND Generator overload condition is determined by generator frequency. Loads are shed when frequency is less than 58 Hz for three seconds or less than 50 Hz for ½ second (for 60 Hz systems).

Installation Section 3 Installation 3.1 — Introduction to Installation This equipment has been wired and tested at the factory. Installing the switch includes the following procedures: • • • • • Mounting the enclosure. Connecting power source and load leads. Connecting the generator start and sensing circuit. Connecting any auxiliary contact (if needed). Testing functions. 3.2 — Mounting Mounting dimensions for the transfer switch enclosure are in this manual. Enclosures are typically wallmounted.
Installation 3.5.1— Control of Air Conditioner Load Maximum Wire Length Recommended Wire Size 1-115 ft (1-35m) No. 18 AWG. 116-185 ft (36-56m) No. 16 AWG. 186-295 ft (57-89m) No. 14 AWG. 296-460 ft (90-140m) No. 12 AWG. Exception: Conductors of AC and DC circuits, rated 1000 volts nominal, or less, shall be permitted to occupy the same equipment, cable, or conduit.
Installation 3.6 — Auxiliary Contacts If desired, there are Auxiliary Contacts 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 (D). See Figure 3-2. Contact operation is shown in the following chart: Switch Position Utility Standby Common to Normally Open Open Closed Common to Normally Closed Closed Open NOTE: Auxiliary Contacts are rated 10 amps at 125 or 250 volts AC.

Operation Section 4 Operation 4.1 — Functional Tests and Adjustments • Manual operation handle in the DOWN position LOAD terminals (T1, T2) are connected to EMERGENCY terminals (E1, E2). 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.
Operation contacts are closed in the GENERATOR (STANDBY) position. No further action is required. If the handle is UP, proceed with Step 1. 1. With the handle inserted into the movable contact carrier arm, move the handle DOWN. Be sure to hold on to the handle as it will move quickly after the center of travel. 2. Remove manual operating handle from movable contact carrier arm. Return handle to storage bracket. 3. DANGER Electrocution. High voltage is present at transfer switch and terminals.
Operation • With maximum rated load applied, check voltage • After approximately 15 seconds, the switch should and frequency across transfer switch terminals E1 and E2. Voltage should be greater than 230 VAC (240 VAC system); frequency should be greater than 59 Hz. • Verify that the gas pressure remains within acceptable parameters (see the generator Installation Guidelines manual). • Let the generator run under rated load for at least 30 minutes.
Operation 5. After five (5) minutes verify A/C 1 is energized and Status LED A/C 1 is ON. 6. After another 15 seconds, verify A/C 2 is energized and Status LED A/C 2 is ON. 7. After another 15 seconds, verify Load A/C 3 is energized and Status LED Load A/C 3 is ON. 8. After another 15 seconds, verify A/C 4 is energized and Status LED A/C 4 is ON. 4.9 — Testing The Smart Management Module Refer to the SMM Owner’s/Installation Manual for testing that product.
