CAUTION
•Lift the cabinet by the base. When moving the VS-656DC5, never lift by the front cover or the front panel.
Otherwise, the main unit may be dropped causing personal injury or damage to the VS-656DC5.
•Mount the VS-656DC5 on nonflammable material (i.e. metal).
Failure to observe this caution may result in a fire.
•When mounting several Units in an enclosure, install a fan or other cooling device to keep the intake air temperature below 45 °C.
Overheating may cause a fire or damage to the VS-656DC5.
This chapter describes the configuration, location, and space when mounting the VS-656DC5.
2.1Checking Installation Site
Installation Site
Install the VS-656DC5 under the following conditions.
Type |
Ambient Operating Temperature |
Humidity |
|
|
|
Open chassis |
-10 to + 45 °C |
90 % RH or less (no condensation) |
|
|
|
To ensure proper performance and long operating life, follow the recommendations below when choosing a location for installing the VS-656DC5. Make sure the VS-656DC5 is protected from the following conditions:
• Extreme cold and heat
Use only within ambient temperature range: -10 °C to +45 °C
•Rain, moisture
•Oil sprays, splashes
•Salt spray
•Direct sunlight (Avoid using outdoors.)
•Corrosive gases or liquids
•Dust or metallic particles in the air
•Physical shock, vibration
•Magnetic noise (Example: welding machines, power devices, etc.)
•High humidity
•Radioactive materials
•Combustibles: thinners, solvents, etc.
E-5
Controlling the Ambient Temperature
To enhance the reliability of operation, the VS-656DC5 should be installed in an environment free from extreme temperature increases. If the VS-656DC5 is installed in an enclosed environment, such as a box, use a cooling fan or air conditioner to maintain the internal air temperature below 45 °C.
Protecting the VS-656DC5 from Foreign Matter
Place a cover over the VS-656DC5 during installation to shield it from metal powder produced by drilling.
Always remove the cover from the VS-656DC5 after completing installation. Otherwise, ventilation will be reduced, causing the VS-656DC5 to overheat.
2.2Clearances
Install the VS-656DC5 vertically and allow sufficient clearances for effective cooling as shown in Fig. 3.

WARNING
•Only commence wiring after verifying that the power supply is tunred OFF.
Failure to observe this warning may result in an electric shock or a fire.
•Wiring should be performed only by qualified personnel.
Failure to observe this warning may result in an electric shock or a fire.
•Make sure to ground the ground terminal 
before connecting the other terminals. (200 V class: Ground to 100 Ω or less, 400 V class: Ground to 10 Ω or less).
Failure to boserve this warning may result in an electric shock or a fire.
CAUTION
•Verify that the VS-656DC5 rated voltage coincides with the AC power supply voltage.
Failure to observe this caution may result in personal injury or a fire.
•Do not perform a withstand voltage test of the VS-656DC5.
Failure to observe this caution may result in damage to the semi-conductor elements.
•Connect the input AC reactor, harmonics filter reactor, and the harmonics filter capacitor as described in this instruciton manual.
Failure to observe this caution may result in a fire.
•Verify that the rated voltage of the VS-656DC5 coincides with the rated voltage of the Inverter to be connected.
Failure to observe this caution may result in a fire.
•Tighten terminal screws.
Failure to observe this caution may result in a fire.

*1. Be sure to attach the input AC reactor (reactor) and harmonics filter (capacitor).
*2. For models CIMR-D5A2022 to -D5A2075 of the 200 V Class and CIMRD5A4022 to
-D5A4300 of the 400 V Class, the wiring was done prior to shipment. Connections are not needed for CIMR-D5A2015 and -D5A4015.
The terminals r/
1 and 
/
2 in the above diagram are the terminal names for 200 V Class VS-656DC5 with 37 to 75 kW. The terminal names are as follows respectively for each VS656DC5 capacity:
y 200 V Class 22 kW, 400 V Class 22 to 45 kW: |
/ |
2, t/ 3 |
( |
/ |
2 and 1/ 21, t/ 3 and t1/ 31 are |
connected respectively.)
y 400 V Class 75 and 160 kW: r/
1, 
400/
2400
*3. When a noise filter is attached on the VS-656DC5 power supply side, use a noise filter of the reactor type (without a capacitor) such as finemet zero-phase reactor, and attach it behind the MCCB at the power supply side. Do not use a capacitor-built-in type noise filter since the harmonic components may overheat or damage the capacitor.
