5. Be sure all connections are tight and coat the terminals and
cable ends with dialectic grease.
WARNING – The electrolyte is a diluted sulfuric acid that is
harmful to the skin and eyes. It is electrically conductive and
corrosive. The following precautions must always be taken:
* Always wear full eye protection and protective clothing
* Where electrolyte contacts the skin, wash off immediately
with water.
* If electrolyte contacts the eyes, flush thoroughly and
immediately with water and seek immediate medical attention
* Spilled electrolyte is to be washed down with an acid neutral
izing agent. A common practice is to use a solution of one
pound of bicarbonate of soda (baking soda) to one gallon of
water. The bicarbonate of soda solution is to be added until
the evidence of reaction, foaming, has ceased. The resulting
liquid is to be flushed with water and the area dried.
DANGER – Explosive Fire Risk
* Never smoke when near batteries
* Do not cause a flame or spark in the battery area
* Always discharge static electricity from your body before
touching batteries by first touching a grounded metal surface
SERVICING BATTERIES
Batteries used on these units may, over time, lose water. This is
especially true if you are using a trickle charger to maintain your
battery. When refilling the battery with water use only distilled
water. Tap water will shorten the service life of the battery.
Never fill the battery above the fill line. Over filling above the
upper level line may cause the electrolyte to overflow, resulting in
corrosion to the engine or nearby parts. Immediately wash off any
spilled electrolyte following the procedure above.
NOTE: Always make sure that a new battery is fully charged
before installing it on a generator set. Failure to do so can cause
damage to the engine control module in the generator set.
All connections must be clean and tight. Check the electrolyte
(fluid) in the battery periodically to be sure it is above the plates.
Never allow the battery to remain in a discharged condition.

CONNECTIONS
NOTICE - CLASS 1 WIRING METHODS ARE TO BE USED FOR
ALL FIELD WIRING CONNECTIONS TO TERMINALS OF A
CLASS 2 CIRCUIT
Note: This symbol always indicates ground where shown.
All wiring must be completed in accordance with the Nation
Electric Code as well as any state or local codes.
You must pay particular attention to wire size requirement for
the amperage of service you are dealing with. The table below
provides you guidance on wire sizing based on both wire type
and amperage. Wire amperage’s have been derated for 40
o
C ambient temperatures operation. See page 8 for wiring
schematic.

***** WARNING *****
*************
A main line circuit breaker has been provided inside the
generator housing. During all wiring installations make
sure the breaker is in the OFF position and the generator
operation switch is in the OFF position.
Neutral Lugs - DE20 has 100 amp neutral lugs. These lugs are
isolated from ground and provided for you to connect your neutral
wires to, from the transfer switch or load distribution center. The
lugs will accommodate #12 AWG to #1/0 Awg and should be
torqued to 50 in. lbs. The DR30 and larger have 225 AMP neutral
lugs and will accommodate #4 AWG to 300 MCM and should be
torqued to 250 in. lbs. The exception is the DE65 single phase
unit which has a 400 amp neutral block. The 400 amp terminal
block lugs will handle wire sizes #1 AWG to 400 MCM and should
be torqued to 300 in. lbs.
Generator Circuit Breaker, This circuit breaker provides overload
protection for the generator. Your power feeds from the load
panel will connect to the open lugs on the circuit breaker. The
generator power feeds have already been wired into one set of
lugs.
The table below gives you the circuit breaker size, lug wire sizes
and torque specification. (see the actual breaker for additional
information and restrictions)
