Dc Output Power; Alarms And Utility Input - Generac Power Systems APS 6.0 Operating & Installation Manual

When replacing the battery, use the following type of
battery: Group 26/26R 12-volt battery with a rating of
525 cold-cranking amps minimum at -17.8º C (0º F).
When using a maintenance-free battery, it is not nec-
essary to check the specific gravity or electrolyte level.
Have these procedures performed at the intervals
specified in the "Service Schedule." A negative ground
system is used. Battery connections are shown on the
wiring diagrams. Make sure the battery is correctly
connected and terminals are tight. Observe battery
polarity when connecting the battery to the generator
set.
DANGER
Do not dispose of the battery in a fire. The
battery is capable of exploding.
A battery presents a risk of electrical shock
and high short circuit current. The following
precautions are to be observed when working
on batteries:
• Remove watches, rings or other metal objects;
• Use tools with insulated handles;
• Wear rubber gloves and boots;
• Do not lay tools or metal parts on top of the
battery; and
• Disconnect charging source prior to connecting or dis-
connecting battery terminals.
Do not open or mutilate the battery. Released
!
electrolyte has been known to be harmful to
the skin and eyes, and to be toxic.
The electrolyte is a dilute sulfuric acid that is
!
harmful to the skin and eyes. It is electrically
conductive and corrosive.
The following procedures are to be observed:
• Wear full eye protection and protective clothing;
• Where electrolyte contacts the skin, wash it off
immediately with water;
• Where electrolyte contacts the eyes, immediately
flush thoroughly 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 1 pound (500 grams) bicarbonate
of soda to 1 gallon (4 liters) or water. The bicar-
bonate 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 procedures are to be followed:
• DO NOT SMOKE when near the battery;

• DO NOT cause flame or spark in battery area; and
• Discharge static electricity from your body before
touching the battery by first touching a grounded
metal surface.
Be sure the Auto/Off/Manual switch is set to
!
the OFF position before connecting the battery
cables. If the switch is set to AUTO or MANUAL,
the generator can crank and start as soon as
the battery cables are connected.
Be sure the utility power supply is turned off,
or sparking may occur at the battery posts as
you attach the cables and cause an explosion.

3.2.2 DC OUTPUT POWER

The DC output from the unit is taken from two 3/8"
terminals located along the bottom edge of the con-
trol panel. There is sufficient thread on these termi-
nals to add the customer power leads and extra lock
nuts without loosening the factory connections
should these connections become loose, ensure the
cables are routed exactly as supplied from the facto-
ry. A short on either of the output cables could dam-
age components within the unit (Figure 3.2).

3.2.3 ALARMS AND UTILITY INPUT

The unit has a number of alarm outputs which can be
monitored via an external source to give information
on the status of the unit (see pages 11 and 12). These
alarm connections are located on the left hand side of
the control panel enclosure. Also on this connection
block are terminals for utility input. The unit
requires a 240V utility input to monitor. During
installation, alarms to be monitored and utility input
connections should be made at this connection block
(Figure 3.3).
