SETUP

Circuit Breakers

To protect the generator from an overload, a 3-pole, 60 amp, main circuit breaker is provided to protect the UVW output terminals from overload. In addition two single-pole, 20 amp GFCI circuit breakers are provided to protect the GFCI receptacles from overload.Two 50 amp load circuit breakers have also been provided to protect the auxiliary receptacles from overload. Make sure to switch ALL circuit breakers to

the "OFF" position prior to starting the engine.

Lubrication Oil

Fill the engine crankcase with lubricating oil through the filler hole, but DO NOT overfill. Make sure the generator is level. and verify that the oil level is maintained between the two notches (Figure 30) on the dipstick. See Table 11 for proper selection of engine oil.

Fuel Check

DANGER - EXPLOSION/FIRE HAZARDS

Fuel spillage on a hot engine can cause a fire or explosion. If fuel spillage occurs, wipe up the spilled fuel completely to prevent fire hazards. NEVER smoke around or near the generator.

Refilling the Fuel System

CAUTION - REFUELINGTHE GENERATOR

ONLY properly trained personel who have read and understand this section should refill the fuel tank system.

Figure 30. Engine Oil Dipstick

When checking the engine oil, be sure to check if the oil is clean. If the oil is not clean, drain the oil by removing the oil drain plug, and refill with the specified amount of oil as outlined in the Isuzu Engine Owner's Manual. Oil should be warm before draining.

Other types of motor oils may be substituted if they meet the following requirements:

This generator has an internal fuel tank located inside the trailer frame and may also be equipped with an environmental fuel tank (Figure 31). ALWAYS fill the fuel tanks with clean fresh #2 diesel fuel. DO NOT fill the fuel tanks beyond their capacities.

Pay attention to the fuel tank capacity when replenishing fuel.The fuel tank cap must be closed tightly after filling. Handle fuel in a safety container. If the container does not have a spout, use a funnel. Wipe up any spilled fuel immediately.

DCA25USI2XF, DCA25USIXF specifications

Multiquip is a renowned name in the construction and industrial equipment sector, known for delivering high-performance generators that cater to various power needs. Two standout models in their lineup are the DCA25USIXF and DCA25USI2XF, both designed for reliability, efficiency, and versatility.

The Multiquip DCA25USIXF is a compact, industrial-grade diesel generator that delivers a powerful 25 kVA, making it ideal for construction sites, outdoor events, and emergency backup applications. This model is powered by a robust Yanmar diesel engine, which ensures high fuel efficiency and low emissions, adhering to stringent environmental standards. The DCA25USIXF features an advanced digital control panel, providing users with an intuitive interface for monitoring performance, voltage output, and operational status. Its sound-attenuated enclosure significantly reduces noise levels, making it suitable for use in noise-sensitive areas.

On the other hand, the DCA25USI2XF model takes power generation a step further by offering dual voltage capabilities, allowing users to switch between 120V and 240V outputs. This flexibility makes it highly versatile, catering to a broader range of tools and equipment. Like the DCA25USIXF, the DCA25USI2XF is also equipped with Yanmar’s reliable diesel engine, which contributes to its durability and long service life. Both models come with a heavy-duty frame to withstand tough conditions, ensuring durability on job sites.

The technology implemented in these generators includes automatic voltage regulation (AVR), which stabilizes voltage output, protecting sensitive equipment from power surges. Additionally, the generators feature a low oil shutdown system, which prevents engine damage by automatically shutting down the generator when oil levels are low. This protective measure not only enhances the longevity of the generator but also contributes to safer operation.

In terms of portability, both models are equipped with rugged wheels and a lifting eye, facilitating easy transportation to various job sites. With their combination of power, efficiency, and advanced features, the Multiquip DCA25USIXF and DCA25USI2XF generators are excellent choices for professionals seeking reliable power solutions in demanding environments. Whether for construction, events, or standby power, these generators deliver exceptional performance tailored to meet diverse needs.
