2.2 Mechanical Installation

WARNING
THIS EQUIPMENT MUST BE EARTHED.
To guarantee the safe operation of the equipment it must be installed and commissioned properly
by qualified personnel in compliance with the warnings laid down in these operating instructions.
Take particular note of the general and regional installation and safety regulations regarding work
on dangerous voltage installations (e.g. VDE), as well as the relevant regulations regarding the
correct use of tools and personal protective gear.
The mains input and motor terminals can carry dangerous voltages even if the inverter is
inoperative. Use insulated screwdrivers only on these terminal blocks.
Environmental Requirements

Temperature
Max. = 50 C
Altitude
If the Inverter is to be installed at an altitude >
1000 m, derating will be required.(Refer to DA 64
Catalogue).
Shock
Do not drop the inverter or expose to sudden
shock.
Vibration
Do not install the inverter in an area where it is
likely to be exposed to constant vibration.
Electro-Magnetic
Do not install the inverter near sources of
Radiation
electro-magnetic radiation.
Atmospheric
Do not install the inverter in an environment
Pollution
which contains atmospheric pollutants such as
dust, corrosive gases, etc.
Water
Take care to site the inverter away from potential
water hazards. e.g. Do not install the inverter
beneath pipes that are subject to condensation.
Overheating
Ensure that the inverter's air vents are not
obstructed.
Make sure that there is an adequate air-flow
through the cabinet, as follows:
1. Using the formula below, calculate the airflow
required.

2. Install cabinet cooling fan(s) if necessary,
Note:
Typical dissipation (Watts) = 3% of inverter
rating.
T = Allowable temperature rise within cabinet
