Separate acceleration and deceleration ramps can be selected by connecting this terminal to +24. These ramps are programmed by parameters 41, 44 and 45. See 21-MODE for more information on when this function is active. 49, 52, 52 MOL Motor Overload input terminal. Requires N.C. contact for operation, referenced to +24. Connected to +24 by a jumper wire at the factory. 10, 60, 72, 73 CTS Coast to Stop. Connecting this terminal to +24 VDC turns the drive output OFF, allowing the motor to coast to a stop. The inverter’s output is cut off, not ramped to a stop. When the terminal is set to 0 V (open), the drive output is reinstated and the output will ramp to the programmed frequency. This function may be used when electro-mechanical brakes are required. This feature can also be accessed in programming by the 41-RSEL parameter to automatically coast to a stop on a stop command. 52, 72, 73 RST External Fault Reset input terminal. After a fault, connecting this terminal to +24 VDC will reset any fault. ST1 ST2 ST3 Open collector NPN transistor output connections. Each output can be individually programmed to respond to any one of eleven conditions (See parameters 72-ST1, 73-ST2 and 74-ST3. Each output can sink up to 50 mA from a 24 VDC source. 6FS This terminal provides a 24 VDC pulse train output which is 6 times or 48 times the output frequency of the inverter. Selected by parameter 88-FRO. 65, 73 COM Control circuit common, electrical isolated from the AC line terminals. 66, 72 SIO+ Positive connection for the Serial Input/Output Operation communication link. Responds to RS 485 protocol (see Section 5). SIO- Negative connection for the Serial Input/Output Operation communication link. Responds to RS 485 protocol (see Section 5). Normally open contact for the Auxiliary Relay. Will close when the relay is activated. Rating is 115 VAC at 1 Amp. 72 59, 72, 73 59 Auxiliary Relay Common terminal. May release by appropriate adjustment at one of eleven preset conditions (see parameter 75-STR). Normally Closed contact for the Auxiliary Relay. Will open when the relay is activated. Rating is 115 VAC at 1 Amp. Table 2.7 2.8 Environmental Considerations The BERGES ACP 6000 Inverter is rated IP 54 (through 37 kW), indoor or outdoor use. This is a sealed unit providing a degree of protection against falling rain, splashing water and hose-directed water. If your inverter will be subjected to high-pressure wash-down or atmospheric contaminants such as acid or caustic vapours, or carbon, metallic, or corrosive dust, contact BERGES for specific instructions. In order to maintain the IP 54 (NEMA 4) integrity of the ACP inverter enclosure, some care must be exercised when the cover is installed. With the smaller chassis configurations (ACP 6000 thru 15 kW), the following cover installation procedure shall be employed: 1. Snug each of the four (4) cover screws into place. 2. Sequentially tighten each screw until the gasket is compressed evenly. Tighten first one corner then the opposing corner to minimize the chance of pinching the gasket. 30.10.97 05_GB Operating manual ACP 6000SLV — 0.75–55 33
