•The AC connection system on all air-cooled PRIMEPACT series generators uses a GROUNDED neutral.

•A separate green ground wire is connected to the recreational vehicle’s junction box.

•Loads connected across T1 (Red) to T2 (White), and T3 (Black) to T2 (White), must not exceed rat- ings for your specific generator (see Section 1.6.3).

NOTE:

Do NOT connect loads in excess of circuit breaker ratings.

6.1LOCATION AND SUPPORT

◆6.1.1 GENERATOR LOCATION

The most desirable location for the generator set is between the vehicle's main frame members. However, this is seldom possible. Most units must be installed on the side of the vehicle and are difficult to reinforce.

Many recreational vehicles have been factory equipped with an area for the generator set. Some vehicles may even have a generator compartment provided by the vehicle manufacturer.

Plan the generator location based on the following:

•The generator set must be installed on a frame- work that is part of the recreational vehicle, as out- lined in Section 6.1.2.

•The location must provide an access opening that is large enough to permit generator removal (unless the generator is to be removed from under- neath the supporting framework).

•The location must provide easy access to frequent- ly serviced components, such as filters, oil drains, spark plugs and other common maintenance parts.

◆ 6.1.2 GENERATOR SUPPORT

The generator must be securely attached to a metal framework that has been made part of the vehicle frame structure by bolting or welding. The metal framework on which the generator will rest and which will restrain the generator set should consist of at least two horizontal beams. These beams should consist of (a) 1-1/2-inch square, 11-gauge steel tubing OR (b) 1-1/2-inch, 11-gauge angle iron. A typical sup- porting frame with horizontal support tubing, is shown in Figure 6.1.

The generator can be installed so that it sits on top of the horizontal support tubing if the vehicle design permits. Another method is to suspend the generator below the horizontal support tubing by means of suit- able, structurally sound metal framework. The fol- lowing general rules apply:

•Vehicle construction MUST be capable of support- ing the weight of the generator.

•Whether the generator is mounted above the hori- zontal support tubing or suspended below the tub- ing, the supporting frame used must be structural- ly sound.

•If the generator cannot be bolted directly to the supporting frame or support tubing, consider using additional tubing, angle brackets or other supports to give the supporting frame sufficient strength.
