2.1 Installation Precautions

CAUTION



Handle the inverter with care to prevent damage to the plastic components. Do not

hold the inverter by the front cover. It may fall off.

 Install the inverter in a place where it is immune to vibration (5.9 m/s2 or less). The

inverter is under great influence of ambient temperature.

 Install in a location where temperature is within the permissible range (-10~50°C).

Maximum Surrounding Air Temperature is 50°C. Models SV004iC5-1, SV004iC5­1F, SV008iC5-1, and SV008iC5-1F can be used in Ambient 40°C. (UL 508C)

<Ambient Temp Checking Location>

 The inverter will be very ho t duri ng oper ation . Inst all it on a non-comb ustibl e surfac e.
 Mount the inverter on a flat, vertical and level surface. Inverter orientation must be

vertical (top up) for proper heat dissipation. Also leave sufficient clearances around

the inverter.

 Protect from moisture and dir ect su nl ight.
 Do not install the inverter in any environment where it is exposed to waterdrops, oil

mist, dust, etc. Install the inverter in a clean place or inside a “totally enclosed” panel

which does not accept any suspended matter.

 When two or more inverters are installed or a ventilation fan is mounted in

inverter panel, the inverters and ventilation fan must be installed in proper
positions with extreme care taken to keep the ambient temperature of the
inverters below the permissible value. If the y are installed in improper positions,
the ambient temperature of the inverters will rise and ventilation effect will be
reduced.

 Install the inverter using screws or bolts to insure the inverter is firmly fastened.

LS inverters are tested to meet Electromagnetic Compatibility (EMC) Directive
89/336/EEC and Low Voltage (LV) Directive 73/23/EEC using a technical
construction file. However, Conformity of the inverter with CE EMC requirements
does not guarantee an entire machine installation complies with CE EMC
requirements. Many factors can influence total machine installation compliance.

Essential Requirements for CE Compliance
Following conditions must be satisfied for LS inverters to meet the CE EMC

requirements.

1. CE compatible LS inverter

2. Installing inverter in an EMC enclosure

3. Grounding enclosure and shielded parts of wire

4. Using shielded cable

5. Use it under industrial environment.

6. It is important that all lead lengths are kept as short as possible and that
incoming mains and outgoing motor cables are kept well separated.
