GASKET-COVER 4N0508 - Caterpillar

The Generator Set Start Module should be installed per the National Electrical Code (NEC) and other applicable codes. The size of the following components should be based on the specifications for the Generator Set Start Module: cable and conduit. Class 1 wiring methods should be used.Electrical Disconnect Switch
A Disconnect Switch (Three-Phase AC) must be installed prior to the Generator Set Start Module. The size of the disconnect switch should be based on the specifications for the Generator Set Start Module.The Caterpillar UPS can optionally be equipped with breakers (supply) that are wired to the output bus of the UPS in order to supply AC power to the Generator Set Start Module.Electrical Conduit
Requirements for the Conduit
Note: The size of the conduit is based upon the size of the wire. The size of the conduit must be in accordance with the National Electrical Code (NEC) and other applicable codes.The following types of conduit may be used: electrical metallic tubing, liquid-tight flexible metallic conduit and nonmetallic conduit. Use suitable waterproof fittings. The holes for the conduit must be punched into the cabinet. The size of the holes for the conduit must reflect the size of the waterproof fittings for a proper seal. Use care when you are making the holes in order to ensure that the interior components are not damaged, and that metal shavings are kept from contaminating the electrical connections and hardware. All metal shavings must be removed from the cabinet before power is applied.Grounding
Requirements and Instructions
The ground wire must be connected before continuing with the installation.
Failure to connect the unit to a suitable grounding electrode can result in electrical shock and may cause injury or death.
Use the same size of conductors and the same number of conductors for each polarity of DC wiring. A single 4/0 wire is the minimum that is required. Route the ground wire from the ground stud of the Generator Set Start Module to a suitable grounding electrode or equivalent. This must be done in accordance with national codes and local codes and ordinances.Note: The maximum length for the ground wire should not exceed 3.05 m (10.00 ft). Refer to the manuals for the generator set for specifications on distances.Electrical Connections and Torque Values
Note: The recommended hardware requirements ensure successful installation and operation of the Generator Set Start Module.24 VDC Connections
Personal injury or death can result from high voltage.When power generation equipment must be in operation to make tests and/or adjustments, high voltage and current are present.Improper test equipment can fail and present a high voltage shock hazard to its user.Make sure the testing equipment is designed for and correctly operated for high voltage and current tests being made.When servicing or repairing electric power generation equipment:
Make sure the unit is off-line (disconnected from utility and/or other generators power service), and either locked out or tagged DO NOT OPERATE.
Remove all fuses.
Make sure the generator engine is stopped.
Make sure all batteries are disconnected.
Make sure all capacitors are discharged.Failure to do so could result in personal injury
