CAUTION

1.

SAVE THIS INSTRUCTIONS-

This manual contains important safety and operating instructions for the 3PA5015 battery charger.

Please read the caution of batteries or devices you want to charge firstly!

2. When charging, batteries can emit explosive gases, therefore it is essential to prevent flames and sparks. The charger is designed for charging lead-acid batteries from 2 to 90 Ah. Do not use for any other purpose.

3. Always provide good ventilation when charging.

4. Use of an attachment not recommended or sold by Shenzhen GRN may result in a risk of fire, electric shock or serious injury to persons.

5. To reduce risk of damage to electric plug and cord, pull by the plug rather than by the cord when disconnecting charger.

6. An extension cord should not be used unless absolutely necessary. Use of an improper extension cord could result in a risk of fire and electric shock. If extension cord must be used, make sure that: a) Pins on plug of extension cord are the same number, size and shape as those of plug on charger; b)

Extension cord is properly wired and in good electrical condition; and c) Wire size is large enough for ac ampere rating as specified in “technical data”.

7. Do not operate charger with a damaged cord or plug-return the charger to the place where purchased.

8. Never operate the charger if it has received a sharp blow, been dropped or otherwise damaged in any way; take is to a qualified serviceman.

9. Do not disassemble the charger; take it to a qualified serviceman when service or repair is required. Incorrect reassembly may result in a risk of electrical shock or fire.

10. To reduce risk of electric shock, unplug charger from AC outlet before attempting any maintenance or cleaning. Turning off controls will not reduce the risk.

3PA5015R 12V Lead-Acid Battery Charger

User’s Manual

March, 2007 Second Version

Brief Introduction

3PA5015 is a new member of a family of professional chargers from

Shenzhen GRN. It represents today’s new technology for lead-acid type battery charging. 3PA5015R programmed four auto stages ( Ud-I-Uo-Up) charging process，It is designed for all kinds of 12V 2~90Ah lead-acid battery, such as SLA, AGM and Gel battery. Stage “Ud” desulfurating the battery through 20V pulse，When the battery recovered, stage “I” will give bulk current charging( 0.8A or 3.5A, defined by user, for 2~8Ah 0.8A is prefer, 12~90Ah should select 3.5A). Then, “Uo” stage is followed, the output voltage is fixed on

0.4A；stage”Up” will turn on duty. At this stage, the battery is charged completely and the charger give some pulse to maintenance the battery.

Connect positive charger clip (red) to positive battery terminal, the black clip to negative. (You can use other appendix wires to connect battery)

Connect the AC cord to the socket, The red alarm indication light will indicate a battery which is connected to reverse polarity.

Pressing the “MODE-button” and stepping forward one press at a time until the required mode is reached, the button is then release

When the “charging finished” led lights up, the battery is fully charged.

When disconnecting charger, disconnect in reverse sequence from connecting procedure

The table shows the duration of the Bulk stepup to about 80% state of charge.
