SAFETY INSTRUCTIONS
Warning !
Read all the instructions and cautions before using the PowerMon device. Thornwave Labs Inc
does not assume responsibility for any injury or property damage caused by improper installation, bad
wiring or use of PowerMon outside of its intended purpose. The device should be installed by a
professional.
Warning !
The PowerMon device should not be used for any medical purposes, life sustaining equipment,
safety applications or any application where equipment failure can cause injury, death, fires, or any other
hazard.
Warning !
There are no serviceable parts or fuses inside the power meter! Do not disassemble or attempt
to repair! The unit operates with voltages up to 75V which can be lethal or cause serious and permanent
injury.
Warning !
Do not submerge under water or other liquids. The device is weatherproof but not waterproof.
Warning !
The device is to be connected to DC circuits only, not exceeding 75V and 60A (using the integrated
current shunt). Failure to do so will result in equipment damage. Higher currents are supported when
using an external current shunt. Confirm that all connections are tight to avoid excessive heating and
sparks. Never connect the V1 or V2 terminals to a power source without using a fuse or circuit breaker.
A 0.1A to 2A fuse or circuit breaker is required.
Warning !
Batteries are dangerous! Do not short-circuit a battery or the power meter. Batteries can produce
flammable and explosive gases and can generate extremely high currents that can lead to serious
consequences including explosion, fire, damage to equipment, personal injury and even death. It is the
user’s responsibility to operate the equipment in a safe manner. Do not charge batteries in an enclosed
environment unless allowed by the manufacturer of the battery. Never connect a load to a battery
without using fuses or circuit breakers properly sized for the wires/ equipment.
