Safety Instructions

Caution

Read owners manual BEFORE wiring or powering up the RE-4500.

Caution

DO NOT cover or obstruct ventilation openings. DO NOT mount in

a zero-clearance compartment. Overheating may result.

Warning

Under high ambient temperature / high-power-output conditions

some parts of the inverter may become hot enough to cause

burns. The unit should be installed so that it is not to be contacted

by personnel.

Warning

This equipment employs components that tend to produce arcs

and sparks. To prevent fire or explosion, DO NOT install in

confined areas or compartments that contain batteries or

flammable gases and materials.

Warning

Improper use of this product may result in risk of electrical shock.

Both AC and DC voltage sources are terminated inside this

equipment.

Battery connections are for disconnection only, NOT for current

interruption.

General Precautions Do not expose the inverter/charger to direct water spray, rain, or

snow.

To reduce the risk of a fire hazard, do not cover or obstruct the

ventilation openings.

Do not install the inverter in a zero clearance compartment. This

may result in overheating and/or diminished performance.

To avoid the risk of fire, electrical shock, or injury to persons, do

not use attachments not recommended or sold by Vanner

Incorporated.

Vanner recommends that all AC and DC electrical wiring be

performed by a licensed electrician or a qualified technician to

ensure compliance with all applicable national and local wiring

regulations.

To avoid a risk of fire and/or electrical shock, always verify wiring

connections are in good electrical condition. All external

conductors must use proper wire size to avoid dangerous

overheating and/or diminished performance.

If the inverter has been dropped or damaged in any way, do not

operate the inverter until it has been verified to be safe by a

qualified technician.

To reduce the risk of electrical shock, always disconnect the AC

and DC connections using the code required AC and DC

disconnects. The On/Off switch only turns off the Inverter

electronics. Dangerous AC and DC Voltages Are Still Present!

The inverter must be properly grounded in accordance with local

and national codes and ordinances before operation. For most

installations, the negative (ground) conductor should be bonded

to the grounding system at one and only one point in the system.

For optimum inverter/charger performance, battery temperature

should be above 32 degrees Fahrenheit.

Do not disassemble the inverter/charger. See the service section

of this manual for instructions on obtaining service. Attempting

to service the inverter yourself may result in a risk of electrical

shock, fire and/or loss of warranty.

Always use service disconnects to break the circuit before

attempting any kind of servicing of the RE-4500. DO NOT attempt

to service the unit while still actively connected to a power

source of any kind.

Explosive Gas Precautions

This equipment contains components, which tend to produce arcs

or sparks. To prevent fire or explosion, do not install in

compartments containing batteries or flammable materials, or in

locations that require ignition protected equipment. This includes

any space containing gasoline-powered machinery, fuel tanks, or

joints, fittings, or other connections between components of the

fuel system.

To reduce the risk of battery explosion, follow these instructions,

the battery manufacturer instructions, and the instructions of the

manufacturer of the equipment in which the battery is installed.

Working near a lead-acid battery is dangerous. Batteries generate

explosive gases during normal battery operation.

Battery Precautions

Always have someone within range of your voice to come to your

aid when you work near a lead-acid battery.

Have close access to plenty of fresh water and soap in case

battery acid contacts skin, clothing, or eyes.

Always wear complete eye protection and clothing protection.

Avoid touching eyes while working near batteries.

If battery acid contacts skin or clothing, wash immediately with

soap and water. If acid enters eye, immediately flood eye with

running cold water for at least 20 minutes. Get medical attention

immediately.

NEVER smoke or allow a spark or flame near a battery. Gases

produced by batteries are explosive.

Be careful when working with metal tools around batteries.

Potentials exist for sparks or short-circuit of the battery or other

electrical part which could cause an explosion.

Before attempting any sort of wiring for the DC supply to the

Inverter, turnoff the DC disconnect associated with the Batteries.

For Safety, ALWAYS check the operation of the disconnect with a

voltmeter!

In addition to the lethal current associated with the batteries, care

must be taken to avoid any potential problems or explosions from

the batteries. ALWAYS comply with the battery manufacturer’s

and local code requirements/guidelines for the installed battery

system.

Code Compliance Vanner Model RE-4500 is certified by Underwriter’s
