2.1. General Precautions
Before using the unit, read all instructions and cautionary markings on:
1. The Power Tower unit
2. The Power Tower Batteries
3. All appropriate sections of this manual
CAUTION - To reduce risk of injury, charge only HPS Power Tower rechargeable batteries. Other
types of batteries may rupture, causing personal injury and damage.
DO NOT expose the unit to rain, snow or liquids of any type. The unit is designed for indoor use
only.
DO NOT disassemble the unit. Take it to a qualified service center when service or repair is required.
Incorrect re-assembly may result in a risk of electric shock or fire.
To reduce risk of electric shock, disconnect all wiring before attempting any maintenance or
cleaning. Simply turning off the unit without disconnecting wiring will not reduce this risk.
CAUTION - Batteries and Inverters may only be installed by a qualified professional (e.g. solar
installer). If you have any questions, please contact HPS.
NEVER charge a frozen battery.
USE CAUTION when working with metal tools on or around batteries. The potential exists to drop a
tool and short-circuit the batteries or other electrical parts resulting in sparks that could cause an
explosion.
Turn OFF Power Tower battery switch and disconnect all wiring before installation or while
performing repairs or maintenance.
When the PV module or panel is exposed to light, it starts to supply high voltage DC power. Be sure
to turn off the DC Breaker switch before commencing maintenance, and make sure the cables from
the PV panel are properly sealed after disconnection.
GROUNDING INSTRUCTIONS - The Power Tower should be connected to a grounded permanent
wiring system. For most installations, the Ground Lug should be bonded to the grounding system at
one (and only one point) in the system. All installations should comply with all national and local
codes and ordinances.
AVOID AC output short-circuit, DC input short-circuit and DO NOT connect the mains while DC input
short-circuit
