If the generator is received during cold weather, allow the unit to reach room temperature before you remove the protective packing material. Warming the generator to room temperature will prevent the following problems:
- Water condensation on cold surfaces
- Early failures due to wet windings
- Early failures due to wet insulating materials
 |
|
Improper lift rigging can allow unit to tumble causing injury and damage. |

|
Do not use the engine lifting eyes to remove the engine and generator together. |
Unpack the equipment with care in order to avoid scratching painted surfaces. Move the unit to the mounting location. Follow the instructions under the "Product Lifting" topic. The hoist and the hoist cables should have a rating that is greater than the weight of the generator.
If the generator is not installed immediately, refer to the "Product Storage" topic for the proper considerations for storing the unit.
The location of the generator must comply with all local regulations. The location of the generator must also comply with all special industrial regulations. Locate the generator in an area that meets the following requirements:
- Clean
- Dry
- Well ventilated
- Easily accessible for inspection and maintenance
- Open generator sets shall be installed and located in a manner that contact with people is minimized.
Do not obstruct air inlet openings. Do not obstruct discharge openings. Air flow must reach these openings. If the generator is exposed to harsh environmental conditions, the generator can be modified in the field in order to add filters and space heaters. In addition, a more rigid periodic maintenance schedule should be established.
Note: For further information concerning the installation of this generator set, see the appropriate Application and Installation Guide.
IMPORTANT SAFETY INSTRUCTIONS - SAVE THESE INSTRUCTIONS
This manual contains important instructions that shall be followed during installation and maintenance of the generator and batteries.
Factory UL Listed option requires generator set be installed to the minimum UL requirements contained in this section. Installation and sizing shall be performed by qualified personnel. Other installation site requirements may apply in addition to those contained in this section.
Load Connections – Generator Set Output
For units equipped with P– frame breaker: Installer shall connect conductors in accordance with separate P-frame breaker terminal instruction provided with unit. All conductors shall be sized based upon the
Unit ground bar shall be connected in accordance with National Electrical Code, ANSI/NFPA 70, Article 250. Installer shall use UL Listed terminal connectors and install in accordance with terminal connector manufacturer instructions. Terminal connectors shall be used within UL rating limit and suitable for the application. A field wiring ground terminal shall be sized for the connection based on the minimum ground conductor size required by UL as shown in Column 4 of Table 1.
Over-current protection devices
For units without installed circuit breaker over-current protection option, installer shall use off package mounted UL Listed circuit breaker within 7.6 m (25 feet) of generator set. Circuit breaker shall be sized to a minimum of 100% of package rated current as shown in Column 2 of Table 1. The circuit breaker shall not exceed 125% of the package rating as shown in Column 3 of Table 1.
| Generator AC Voltage Output | Package Rated Current | 125% Rated Current | Minimum size of equipment grounding conductor | |
| AWG or kcmil | ||||
| (Volts) | (Amps) | (Amps) | Copper | Aluminum or copper-clad aluminum |
| 600 | 600 | 750 | 1/0 | 3/0 |
| 480 | 750 | 930 | 2/0 | 4/0 |
| 208 | 1730 | 2160 | 350 | 600 |
Field Wiring – EMCP 4.2 and 4.4 Controller Interface
Installer shall use Class 1 wiring methods for all controller (customer) connections with following exception. Class 2 wiring methods shall be allowed for Class 2 controller interface wiring when Class 2 conductors are shielded with UL Listed/recognized insulation sleeve or conduit rated to 600V for each individual circuit.
