Installation
$
Do not connect the ground wire to any pipe
that carries a flammable or explosive sub-
stance – FIRE or an EXPLOSION may result.
Proper grounding helps protect personnel against electrical shock
in the event of a ground fault condition in the generator or in con-
nected electrical devices. In addition, grounding helps dissipate
static electricity that often builds up in ungrounded devices.
GENERATOR AC NEUTRAL
CONNECTIONS
Grounding is recommended only at one point in the system.
Consult local building codes for proper neutral grounding require-
ments.
TRANSFER SWITCH START SIGNAL
CONNECTIONS
If the generator is to be installed with a standard automatic transfer
switch, such as a GTS type switch, it will be necessary to connect
the two-wire start control system.
Connect the two-wire start signal from the automatic transfer
switch to the automatic start connection, which is located in the
lower rear of the AC connection panel. Match wires 178 and 183
in the transfer switch to 178 and 183 on the terminal strip in the
connection box. The conductors for the two-wire start circuit must
be in their own conduit.
If the generator is to be installed with an HTS-type transfer switch,
a different connection method is needed. Use shielded 2-wire
communications cable (such a Belden #9460) to make the con-
nection from the HTS transfer switch to the engine generator
connection panel. This cable is to be routed in a separate conduit
between the HTS transfer switch and the engine generator. The
cable is to be connected as follows:
HTS transfer switch - 4 position terminal block, in the bottom of
the transfer switch enclosure (labeled "comm. Ports").
Engine generator - terminal strip located in the lower rear of the
AC connection panel. Connect the RS485+ and RS485- to the
respective terminals in switch and generator. Do not connect the
shield at transfer switch end.
BATTERY INSTALLATION
Standby generators installed with automatic
‹
transfer switches will crank and start auto-
matically when NORMAL (UTILITY) source
voltage is removed or is below an acceptable
preset level. To prevent such automatic start-
up and possible injury to personnel, do not
connect battery cables until certain that nor-
mal source voltage at the transfer switch is
correct and the system is ready to be placed
into operation.

Storage batteries give off explosive hydrogen
gas. This gas can form an explosive mixture
around the battery for several hours after
charging. The slightest spark can ignite the
gas and cause an explosion. Such an explo-
sion can shatter the battery and cause blind-
ness or other injury. Any area that houses a
storage battery must be properly ventilated.
Do not allow smoking, open flame, sparks or
any spark producing tools or equipment near
the battery.
Battery electrolyte fluid is an extremely
‹
caustic sulfuric acid solution that can cause
severe burns. Do not permit fluid to contact
eyes, skin, clothing, painted surfaces, etc.
Wear protective goggles, protective clothing
and gloves when handling a battery. If fluid
is spilled, flush the affected area immedi-
ately with clear water.
$
Do not dispose of the battery in a fire. The
battery is capable of exploding.
Do not open or mutilate the battery.
‹
Released electrolyte can be toxic and harm-
ful to the skin and eyes.

The battery represents a risk of high short
circuit current. When working on the battery,
always remove watches, rings or other metal
objects, and only use tools that have insu-
lated handles.
VENTED BATTERIES
The electrolyte is a dilute sulfuric acid that is
‹
harmful to the skin and eyes. It is electrically
conductive and corrosive. The following pro-
cedures are to be observed:
• Wear full eye protection and protective cloth-
ing,
• Where electrolyte contacts the skin, wash it off
immediately with water,
• Where electrolyte contacts the eyes, flush thor-
oughly and immediately with water and seek
medical attention, and
• Spilled electrolyte is to be washed down with
an acid-neutralizing agent. A common practice
is to use a solution of one pound (500 grams)
bicarbonate of soda to one gallon (4 liters) 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.

Lead acid batteries present a risk of fire
because they generate hydrogen gas. The
following procedure are to be followed:
