PCH-202
Please read all warnings and safety guide before operating PCH-202. Operator is
responsible for any regulations required by special applications. Please do not
connect AC power before installation. Warranty voids if instructions are not followed
and may risk of electrical shock, fire or injury.
。
Important Safety Guide
1. Do not place charger under rain, sunlight, dust condition, acidic or corrosive gas
environment.
2. To prevent overheating, do not block ventilation fan.
3. PCH-202 is equipped with automatic charging loop detection. Charger does not need to
be turned off or disconnected from the battery, it enters maintenance mode after the
battery has been fully charged.
4. Please use only factory parts and suggested accessories. Unauthorized parts may risk
of shock, fire, or injury.
5. Please do not disassemble PCH-202. Attempting to repair may risk of fire and electrical
shock.
6. PCH-202 contains residual power even after removed from the battery and AC power.
7. Please make sure the AC ground wire from PCH-202 is properly installed. Improper
connection may risk of electrical shock, fire, or injury.
8. Please remove ac power and battery first and then perform maintenance.
9. Please use supplied wires or same grade wires.
10.Due to the nature of lead acid battery, hydrogen and oxygen gas are been released during
charging. Please operate charger in a well-ventilated area.
11.Please do not press DC start output button for a long period of time. DC start is designed
as force output when battery is below 6V and charger cannot automatically start
charging.

1、Installation
1. To prevent sparks during power up, please make sure the power switch is in off position
before plug-in the ac power cord.
2. Connect positive and negative wires to the battery before switch the power to “ON”
position.
3. PCH-202 is equipped with short circuit, over load, and reverses polarity protections.
4. When the battery is below minimum charging voltage, charger ceases the output. Press
DC start button, PCH-202 starts charging regardless of battery voltage. If error LED
is ON, the overload or reverse polarity is present, please check the wire connections.
5. The minimum charging voltage of a 24V battery must be greater than 6V, otherwise the
PCH-202 detects as battery error and cease the output. Press DC start to force charge
battery.
6. PCH-202 automatically switches between float and equalized mode according to the battery
condition.
7. Only supply AC input between 110V (90~130V)/220V(190~240V),50-60Hz, exceeding the range
might cause error or damage the charger.
8. Avoid rain, sun light, dust, flammable material, and acidic gas.
9. To maintain the best performance of the charger, please keep the environment between
-25℃ to 35℃, cooler the better.
10.Please make sure the charger is installed in a well-ventilated area. To avoid bad
circulation and prolong the life of charger, keep at least 10CM between wall and
ventilation fan.
