The unit must be secured to a suitable, non-combustible, vertical surface (a load bearing wall for the
heavier MIDIMASTER Eco range). Depending on frame size, use nuts, bolts and washers as shown in

SAFETY INFORMATION AND
ENVIRONMENTAL REQUIREMENTS
•
This equipment must be earthed
•
Do not energise the equipment with the cover
removed
•
The equipment must be installed and
commissioned only by qualified personnel
•
Obey all general and regional installation and
safety regulations relating to work on high
voltage installations, as well as regulations
covering correct use of tools and personal
protective equipment
•
Make sure that the clearance for cooling inlets
and outlets, above and below the inverter, is at
least 150mm. If the unit is installed in a
cabinet, it may be necessary to install cabinet
cooling fans.
Use the formula below to calculate the air-
flow required:
Air-flow (m
3
/ hr) = (Dissipated Watts /
∆
T) x
3.1
Typical dissipation (Watts) = 3% of inverter
rating.
∆
T = Allowable temperature rise within
cabinet in °C.
3.1 = Specific heat of air at sea level.
•
Use insulated hand tools on mains input and
motor terminals. Dangerous voltages can be
present even when the inverter is not
operating
•
Do not exceed operating temperature range
0°C to 50
°
C for the MICROMASTER Eco, or
0°C to 40
°
C for the MIDIMASTER Eco range
•
De-rate the inverter if operating at altitude
above 1000m
•
Do not install the inverter where it will be
subject to shock, vibration, electro-magnetic
radiation, water hazards, or atmospheric
pollutants such as dust or corrosive gasses
