4.2 Mounting Procedure for Two Load Centers

When the main service is 400A or more and/or 2 or more load centers will be installed, dedicate one load center to non-emergency loads (not connected to generator power) and the 2nd load center as an OVATION™ Model 1001 or 2001D/R load center/transfer switch for generator back-up circuits. Follow 4.1 Standard Mounting Procedures for installation.

4.3 Connecting the Low Voltage Cable to the OVATION™ Series ATS

The low voltage cable delivers important signaling information between the generator and the OVATION™ ATS for generator startup, running and shutdown and powers the Control Module with the generator battery. Some generators utilize all four wires for signaling while others use only three or two wires. Since no two generators are alike, the termination of the low voltage cable to the generator will be different from manufacturer to manufacturer. Refer to the generator manufacturer’s installation instructions and visit http://www.gen-tran.com/support/installation instructions for additional information for proper connection of low voltage wiring.

Three or four-conductor, UL listed, 300V, 18 AWG (Type TC recommended) wire minimum is required.

Low voltage wire cannot be installed in the same conduit as the generator wires UNLESS at least 300V rated.

The low voltage cable will be terminated in the transfer switch on the control module. There is a small black 4-position terminal connector (delivered plugged into J6 on the Control Module) that is labeled to indicate how to connect the low voltage cable. The low voltage cable should be stripped about ¼” and inserted in the terminal block and tightened as shown in Figure 4.3. A 12 VDC contact closure is provided between Pin 1&3 (close to run). If a voltage free contact closure is required to start/run/stop the generator, terminate Pin 1&3 to the coil side of the ATSRK Relay Kit and terminate the primary side of the relay to the generator control.

Table 4.3

PIN NUMBER on J6	FUNCTION
1	Ground (-12VDC)
2	Battery + (+12VDC)
3	ON/OFF (RUN)
4	Crank/Start

Note: Pin 1 is located towards the top of the Control Module.

IMPORTANT: The OVATION™ Series ATS is powered by the 12VDC battery located in the generator. The + and -12VDC MUST be brought over from the generator. If the generator is a 2-wire control system, use a 3-wire conductor to ensure a -12VDC signal is wired to the transfer switch on PIN 1. If 3-wire conductor is not available, install a jumper between PIN 1 and the ground bar in the

OVATION™ ATS.
