WARNING

Generator requirements for Emerson Energy Systems Power Systems

For information on selecting ac generators that will effectively maintain peak performance and operating characteristics, for all Astec APS power systems, go to the partners’ section of the Emerson Energy Systems web site at www.EmersonEnergy-NA.com. To obtain access to the partners’ section follow the instructions found on the partner’ page, or dial our nearest local 1− 800 technical support line ( refer to “Appendix C : Technical service assistance” of this manual for the telephone number ).

DANGER

Grounding

The frame ground leads must be connected before any other leads. This is to prevent the cabinets and any other metal structures from carrying dangerous ac or dc voltage levels.

DANGER

Protecting against electrical shocks

The cabling of the power plant, and all other required cabling, must be carried out by qualified personnel and in conformance with local and national electrical codes. AC input voltages to the rectifiers are at a dangerous level. Ensure that the circuit breakers are locked in the OFF position in the ac service panel before working on the power plant. Dangerous voltages may be present at the output dc terminals even if the rectifiers are OFF. Use a voltmeter to verify for the presence of such voltages. Do not put the circuit breakers to ON until the entire system has been assembled and you have been instructed to do so. Verify, and identify with a tag, the proper polarity of the battery leads before connecting them to the power plant.
