Safety Information And Environmental Requirements - Siemens Midimaster Eco Reference Manual

The unit must be secured to a suitable, non-combustible, vertical surface (a load bearing wall for the
heavier MIDIMASTER Eco range). Note that the frame size 9 MIDIMASTER Eco units are floor
mounted. Depending on frame size, use nuts, bolts and washers as shown in the following table:
Frame size A
Bolt size M4
Quantity 2
Torque (Nm) 2.5
 22
Use the formula below to calculate the air-
flow required: Air-flow (m
(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.

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 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.
