Manual Operation | Generac Power Systems 004635-3, 004678-2 instruction

Section 3 — Operation

ATS “HS” Type Transfer Switch

Connect power source load conductors to clearly marked transfer mechanism terminal lugs as follows

1.Connect UTILITY (NORMAL) power source cables to switch terminals N1, N2.

2.Connect EMERGENCY (STANDBY) source power cables to transfer switch terminals E1, E2.

3.Connect customer LOAD leads to switch termi- nals T1, T2.

Conductors must be properly supported, of approved insulative qualities, protected by approved conduit, and of the correct wire gauge size in accordance with applicable codes.

Be sure to maintain proper electrical clearance between live metal parts and grounded metal. Allow at least 1/2 inch for 100-400 amp circuits.

2.5CONNECTING START CIRCUIT

WIRES

Control system interconnections (Section 6) consist of UTILITY 1 (N1) and UTILITY 2 (N2), LOAD 1 (T1) and LOAD 2 (T2), and leads 23 and 194 when used in conjunction with some water-cooled generators. Recommended wire gauge sizes for this wiring depends on the length of the wire, as recommended below:

	MAXIMUM WIRE LENGTH	RECOMMENDED WIRE
		SIZE
	460 feet (140m)	No. 18 AWG.
	461 to 730 feet (223m)	No. 16 AWG.
	731 to 1,160 feet (354m)	No. 14 AWG.
	1,161 to 1,850 feet (565m)	No. 12 AWG.

NOTE:

If there are no matching terminal connections for LOAD 1 (T1) and LOAD 2 (T2) in the generator control panel, do not connect these wires. Failure of the control board will occur if connected.

3.1FUNCTIONAL TESTS AND

ADJUSTMENTS

Following transfer switch installation and inter- connection, inspect the entire installation careful- ly. A competent, qualified electrician should inspect it. The installation should comply strictly with all applicable codes, standards, and regula- tions. When absolutely certain the installation is proper and correct, complete a functional test of the system.

Perform functional tests in the exact order

!presented in this manual, or damage could be done to the switch.

IMPORTANT: Before proceeding with functional tests, read and make sure all instructions and infor- mation in this section are understood. Also read the information and instructions of labels and decals affixed to the switch. Note any options or accessories that might be installed and review their operation.

3.2MANUAL OPERATION

DANGER

Do NOT manually transfer under load.

!Disconnect transfer switch from all power sources by approved means, such as a main circuit breaker(s).

A manual HANDLE is shipped with the transfer switch. Manual operation must be checked BEFORE the transfer switch is operated electrically. To check manual operation, proceed as follows:

1.Turn the generator’s AUTO-OFF-MANUAL switch to OFF.

2.Turn OFF both UTILITY and EMERGENCY power supplies to the transfer switch, with what- ever means provided (such as the main line cir- cuit breakers).

3.Note position of transfer mechanism main con- tacts by observing the moveable contact carrier arm.

•Manual operation handle towards the top of switch mechanism - LOAD terminals (T1, T2) are connected to UTILITY terminals (N1, N2).

•Manual operation handle towards the bottom of switch mechanism - LOAD terminals (T1, T2) are connected to EMERGENCY terminals (E1, E2).

Do not use excessive force when operating

!the transfer switch manually or damage could be done to the manual handle.

◆3.2.1 CLOSE TO NORMAL SOURCE SIDE

Before proceeding, verify the position of the switch by observing the position of manual operation handle in Figure 3.1. If the handle is UP, the contacts are closed in the NORMAL position, no further action is required. If the handle is DOWN, proceed with Step 1.

Step 1: With the handle inserted into the actuating shaft, move handle UP. Be sure to hold on to the handle as it will move quickly after the center of travel.
