generator set as follows: (1) Move the generator set master
switch to the OFF position. (2) Disconnect the power to the
battery charger. (3) Remove the battery cables, negative (--)

Introduction

Read and follow the safety precautions included in this
manual. Pay attention to the decals on the equipment
and follow the instructions below.
All personnel involved in handling, site preparation,
D
installation, testing, operation, and maintenance
should be thoroughly familiar with the information in
this manual and the customer drawings provided
before working on this equipment.
Never make interlocks inoperative or operate the
D
equipment with any safety barriers removed.
Always assume that all high-voltage parts are
D
energized until it is certain that they are de-energized.
Use only test equipment rated for the service
D
intended.
Check interconnection diagrams and make sure
D
there are no potential backfeed sources.
Never disconnect the main trip source of energized
D
equipment.
Use out-of-service tags and padlocks when working
D
on equipment. Leave tags in place until the work is
completed and the equipment is ready to be put back
into service.
The complete assembly arrangement determines if
D
the top or bottom contacts are the line side; both can
be energized when the circuit breaker is removed
from the compartment.
Do not use liquid fire extinguishers or water on
D
electrical fires. Before extinguishing fires within the
assembly, be absolutely certain that the main power
source is disconnected and the main and all feeder
breakers are tripped.
The Decision-Makerr 3500 generator set controller
provides generator set advanced control, system
monitoring, and system diagnostics for paralleling
multiple generator sets.
The Decision-Makerr 3500 interfaces the generator set
to other power system equipment and other network
management systems using standard industry network
communications.
The controller uses unique software logic to manage
sophisticated functions, such as voltage regulation,
synchronizing and load-sharing controls, and protective
relays for paralleling up to eight generator sets.
