WARNING

•Read and understand this manual before installing, operating, or servicing this Drive. All warnings, cautions, and instructions must be followed. All activity must be performed by qualified personnel. The Drive must be installed according to this manual and local codes.

•Do not connect or disconnect wiring while the power is on. Do not remove covers or touch circuit boards while the power is on. Do not remove or insert the digital operator while power is on.

•Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the power supply is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50Vdc. To prevent electric shock, wait at least five minutes after all indicators are OFF and measure DC bus voltage level to confirm safe level.

•Do not perform a withstand voltage test on any part of the unit. This equipment uses sensitive devices and may be damaged by high voltage.

WARNING

•The Drive is suitable for circuits capable of delivering not more than 100,000 RMS symmetrical Amperes, 240Vac maximum (200-240V Class) and 480Vac maximum (380-480V Class). Install adequate branch circuit short circuit protection per applicable codes. Failure to do so may result in equipment damage and/or personal injury. Refer to Appendix E for further details.

•Do not connect unapproved LC or RC interference suppression filters, capacitors, or overvoltage protection devices to the output of the Drive. These devices may generate peak currents that exceed Drive specifications.

i

• To avoid unnecessary fault displays caused by contactors or output switches placed between Drive and motor, auxiliary contacts must be properly integrated into the control logic circuit.

•YASKAWA is not responsible for any modification of the product made by the user; doing so will void the warranty. This product must not be modified.

•Verify that the rated voltage of the Drive matches the voltage of the incoming power supply before applying power.

•To meet CE directives, proper line filters and proper installation are required.

•Some drawings in this manual may be shown with protective covers or shields removed, to describe details. These must be replaced before operation.

•Observe electrostatic discharge procedures when handling circuit boards to prevent ESD damage.

•The equipment may start unexpectedly upon application of power. Clear all personnel from the Drive, motor, and machine area before applying power. Secure covers, couplings, shaft keys, and machine loads before energizing the Drive.

•Please do not connect or operate any equipment with visible damage or missing parts. The operating company is responsible for any injuries or equipment damage resulting from failure to heed the warnings in this manual.

Checking and Controlling the Installation Site

Install the Drive in the installation site described below and maintain optimum conditions.

Installation Site

Install the Drive to a non-combustible surface under the following conditions in UL Pollution Degree 2 environments. This excludes wet locations where pollution may become conductive due to moisture, and locations containing conductive foreign matter

		Table 1.5 Installation Site
Type	Ambient Operating Temperature					Humidity
NEMA Type 1	14° F to	104°F	(-10 to	+ 40 °C)		95% RH or less (no condensation)
Open chassis	14° F to	113°F	(-10 to	+ 45 °C)		95% RH or less (no condensation)

Protective covers are attached to the top and bottom of the Drive. It is recommended to remove the protective covers before operating a NEMA Type 1 Drive (Models CIMR-G7U2015/4015 and smaller) in a panel to obtain the 113° (45°C) ambient operating temperature.

Observe the following precautions when installing the Drive. Make sure to install:

•In a clean location which is free from oil mist and dust.

•In an environment where metal shavings, oil, water, or other foreign materials do not get into the Drive.

•In a location free from radioactive materials and combustible materials (e.g. wood).

•In a location free from harmful gases and liquids.

•In a location free from excessive vibration.

•In a location free from chlorides

•In a location away from direct sunlight.

Controlling the Ambient Temperature

To enhance the reliability of operation, the Drive should be installed in an environment free from extreme temperature variation. If the Drive is installed in an enclosure, use a cooling fan or air conditioner to maintain the internal air temperature below 113°F (45°C).

Protecting the Drive from Foreign Matter

During Drive installation and project construction, it is possible to have foreign matter such as metal shavings or wire clippings fall inside the Drive. To prevent foreign matter from falling into the Drive, place a temporary cover over the Drive.

Always remove the temporary cover from the Drive before start-up. Otherwise, ventilation will be reduced, causing the Drive to overheat.

1-10

Installation Orientation and Space
