CONNECTING EXTERNAL DEVICES
Always connect the red (+) positive lead from your charger or other external device (or the included
terminal block) to the red (+) positive terminal on the power supply, and the black (-) negative lead
from your charger or other external device (or the included terminal block) to the black (-) negative
terminal on the power supply.
Note:
The black and red terminal caps can be unscrewed and removed if needed.
WARNING: ALWAYS
ensure polarity is correct when connecting external devices to the power
supply. Reverse polarity will not damage the power supply but it may damage the external device.
WARNING: NEVER
attempt to connect batteries directly to the output of the power supply!
TERMINAL BLOCK ADAPTER
A terminal block adapter is included for convenient
connection of external devices which have alligator clips
on their input power leads. This also allows the adapter
to be located away from the power supply itself which
can be very convenient in crowded work spaces. The
terminal block has two large, metal terminals or “posts”
which are clearly marked for polarity; one terminal is red
for positive (+) polarity, the other terminal is black for
negative (-) polarity. When connecting external devices
to the terminal block, be sure to make a solid physical
connection to avoid intermittent power delivery to the
external device.
WARNING:
Do not allow wires or other metal objects to accidentally make contact simultaneously
with both terminals, as a short circuit condition will exist.
SAFETY FEATURES
The TrakPower 25 Amp Racing Power Supply has a 25 amp solid-state current limiter for overload
protection, plus short circuit protection. If either of these conditions occur, disconnect the supply
from the AC input, wait approximately 15 seconds to allow the device to reset, and then re-connect
to the AC input.
Twin built-in rear mounted cooling fans keep electronics cool to help maintain optimum effi ciency
and extend the life of the power supply.
WARNING:
Do not block the air vents on the power supply. Make sure there is ample room for air to
enter and leave the power supply so heat can dissipate effi ciently.
