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 this manual and local codes. Do not connect or disconnect wiring while the power is on. Do not remove covers or uch circuit boards while the power is on. Do not remove or insert the digital operar while power is on. Before servicing, disconnect all power the equipment. The internal capacir remains charged even after the power supply is turned off. The charge indicar LED will extinguish when the DC bus voltage is below 50Vdc. To prevent electric shock, wait at least five minutes after all indicars are OFF and measure DC bus voltage level 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 00,000 RMS symmetrical Amperes, 40Vac maximum (00-40V Class) and 480Vac maximum ( V Class). Install adequate branch circuit short circuit protection per applicable codes. Failure do so may result in equipment damage and/or personal injury. Refer Appendix E for further details. Do not connect unapproved LC or RC interference suppression filters, capacirs, or overvoltage protection devices the output of the Drive. These devices may generate peak currents that exceed Drive specifications. i

3 To avoid unnecessary fault displays caused by contacrs or output switches placed between Drive and mor, auxiliary contacts must be properly integrated in 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, describe details. These must be replaced before operation. Observe electrostatic discharge procedures when handling circuit boards prevent ESD damage. The equipment may start unexpectedly upon application of power. Clear all personnel from the Drive, mor, 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 heed the warnings in this manual. Intended Use Drives are intended for installation in electrical systems or machinery. The Drives are designed and manufactured in accordance with applicable UL and cul standards, and CE directives.

23 Checking and Controlling the Installation Site Install the Drive in the installation site described below and maintain optimum conditions. Installation Site Install the Drive a non-combustible surface under the following conditions in UL Pollution Degree environments. This excludes wet locations where pollution may become conductive due moisture, and locations containing conductive foreign matter Protective covers are attached the p and botm of the Drive. It is recommended remove the protective covers before operating a NEMA Type Drive (Models CIMR-G7U05/405 and smaller) in a panel obtain the 3 (45 C) ambient operating temperature. Observe the following precautions when installing the Drive. Make sure 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 in 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. Table.5 Installation Site Type Ambient Operating Temperature Humidity NEMA Type 4 F-- 04 F ( C) 95% RH or less (no condensation) chassis 4 F-- 3 F ( C) 95% RH or less (no condensation) 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 maintain the internal air temperature below 3 F (45 C). Protecting the Drive from Foreign Matter During Drive installation and project construction, it is possible have foreign matter such as metal shavings or wire clippings fall inside the Drive. To prevent foreign matter from falling in 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 overheat. -0

24 Installation Orientation and Space Installation Orientation and Space Install the Drive vertically so as not reduce the cooling effect. When installing the Drive, always provide the following installation space allow normal heat dissipation..97in * (50mm) minimum 4.7in (0mm) minimum Air.in (30.5mm) minimum.97in (50mm) minimum.in (30.5mm) minimum 4.75in (0mm) minimum Air Horizontal Clearance Vertical Clearance * For Drive model G7U4300, this clearance dimension is.8in (300mm) minimum. All other models require.97in (50mm) minimum. Fig.8 Drive Installation Orientation and Space IMPORTANT. The same space is required horizontally and vertically for both Chassis (IP00) and Enclosed Wallmounted (IP0, NEMA Type ) Drives.. Always remove the protection covers before installing a or V Class Drive with an output of 5 kw or less in a panel. Always provide enough space for suspension eye bolts and the main circuit lines when installing a or V Class Drive with an output of 8.5 kw or more in a panel. -

47 Wiring the Main Circuits This section describes wiring connections for the main circuit inputs and outputs. Wiring Main Circuit Inputs Observe the following precautions for the main circuit power supply input. Installing a Molded-case Circuit Breaker Always connect the power input terminals (R/L, S/L, and T/L3) and power supply via a molded-case circuit breaker (MCCB) suitable for the Drive. Choose an MCCB with a capacity of.5 times the Drive's rated current. For the MCCB's time characteristics, be sure consider the Drive's overload protection (one minute at 50% of the rated output current). If the same MCCB is be used for more than one Drive, or other devices, set up a sequence so that the power supply will be turned OFF by a fault output, as shown in Fig.5. Power supply 0P4 030: 3-phase, Vac, 50/60 Hz 037 0: 3-phase, Vac, 50/60 Hz 40P4 4300: 3-phase, Vac, 50/60 Hz Drive R/L S/L T/L3 Fault output (NC) * For V class Drives, connect a 460/30 V transformer. Fig.5 MCCB Installation Installing a Ground Fault Interrupter Drive outputs use high-speed switching, so high-frequency leakage current is generated. Therefore, at the Drive primary side, use a ground fault interrupter detect only the leakage current in the frequency range that is hazardous humans and exclude high-frequency leakage current. For the special-purpose ground fault interrupter for Drives, choose a ground fault interrupter with a sensitivity amperage of at least 30 ma per Drive. When using a general ground fault interrupter, choose a ground fault interrupter with a sensitivity amperage of 00 ma or more per Drive and with an operating time of 0. s or more. -6
