If the Inverter is to be installed at an altitude >1000m,
derating will be required. (Refer to DA64 Catalogue)
Do not drop the inverter or expose to sudden shock.
Do not install the inverter in an area where it is likely to
be exposed to constant vibration.
Do not install the inverter near sources of electro-
magnetic radiation.
Do not install the inverter in an environment, which
contains atmospheric pollutants such as dust,
corrosive gases, etc.
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. Avoid installing
the inverter where excessive humidity and
condensation may occur.
Mount the inverter vertically to ensure optimum
cooling. Additional ventilation may be required for
horizontal mounting.
Ensure that the inverter’s air vents are not obstructed,
including the air vent at the front of the unit, which
should be at least 15mm from any obstruction
Make sure that there is an adequate air-flow through
the cabinet, as follows:
1. Using the formula below, calculate the air-flow
required:
Air-flow (m
3
/ hr) = (Dissipated Watts /
∆
T) x 3.1
2. If necessary, install cabinet cooling fan(s).
Note
:
Dissipation (Watts) = 3-5% of inverter rating.
∆
T = Allowable temperature rise within cabinet in °C.
3.1 = Specific heat of air at sea level.

Note: The Plastic Material of the case can be degraded by oil or grease. Care should be taken to
ensure that the mounting surface and fixings are thoroughly degreased before use.
