a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.

do not lift heavy objects unassisted.

Installation

Read the installation instructions before commencing installation activities. For electrical work, follow the local national wiring
standard, regulation, and this installation instructions. The installation shall be in accordance with the Canadian Electrical Code,
Part 1. The wiring methods shall be in accordance with the National Electrical Code, ANSI/NFPA 70.

This product is a safety class I device (supplied with a ground terminal for safety purposes). 

Its AC input and/or output

terminals must be provided with uninterruptible grounding for safety purposes. An additional grounding point is located
on the outside of the product. The ground conductor should be at least 4mm².

 If it can be assumed that the grounding

protection is damaged, the product should be taken out of operation and prevented from accidentally being put into operation
again; contact qualified maintenance personnel.

Ensure that the connection cables are provided with fuses and circuit breakers. Never replace a protective device by a
component of a different type. Refer to the manual for the correct part.

Do not invert neutral and phase when connecting the AC.

Check before switching the device on whether the available voltage source conforms to the configuration settings of the product
as described in the manual.

Ensure that the equipment is used under the correct operating conditions. Never operate it in a wet or dusty environment. Ensure
that there is always sufficient free space around the product for ventilation, and those ventilation openings are not blocked. Install
the product in a heatproof environment. Ensure therefore that there are no chemicals, plastic parts, curtains or other textiles, etc.
in the immediate vicinity of the equipment.

This inverter is provided with an internal isolation transformer providing reinforced insulation

Transport and storage

On storage or transport of the product, ensure that the mains supply and battery leads are disconnected.

No liability can be accepted for damage in transit if the equipment is not transported in its original packaging.

Store the product in a dry environment; the storage temperature should range from –20°C to 60°C.

Refer to the battery manufacturer's manual for information on transport, storage, charging, recharging, and disposal of the battery.
