Safety Information And Environmental Requirements - Siemens MICROMASTER 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). 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
Frame size A units can be DIN rail Mounted.
Frame size 7 units should be lifted using lifting
lugs provided.
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
9-2

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:
/ hr) = (Dissipated Watts / ∆T) x

Air-flow (m
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
