Safety Section
D9124 and High Voltage
The D9124 System connects directly to a 20 Amp, single phase circuit breaker. The high
voltages at these connections are extremely dangerous. Only licensed electricians should
make or service these connections.
Ground the System First
For safety and to help prevent damage from
electrostatic charges or other transient
electrical surges, connect the green
ground wire for the 120 VAC to the
stud shown in Figure 6 before making
any other connections to the panel.
Also connect the two green panel
earth ground wires to the earth
ground stud. All connections to the
ground stud must be made exactly
as shown in Figure 5 .
All connections to the 120 VAC
terminals should be performed
as directed by NEC 70.
Safety Precautions While
Handling High Voltage
Danger! High voltage is present
at the AC Power input terminals,
at Fuse F1, and at connector J8,
near the lower right corner of the
D9142 Power Supply (see
Figure 1 ). Always use the dedicated circuit breaker to remove 120 VAC before removing
the covers to the fuse or terminals block. The terminals and fuse must be covered after
making connections or testing these connections.
Safety Precautions While Handling Batteries
Wear rubber gloves and safety goggles while connecting batteries together. Mixing
batteries of different battery capacities, or mixing batteries from multiple manufacturers is
not recommended.
Unplug the D9142 battery connector J7 before attaching or removing wires at the D9142
Power Supply’s terminals.
Refer to battery manufacturer instructions for further information about batteries and
applicable safety precautions.
