Даже если устройство плавного пуска выключено, в цепи электродвигателя может присутствовать напряжение опасное для жизни. Рекомендуется использовать разделительный контактор, который предназначен для автоматической изоляции при выключенном двигателе. В блоке может быть несколько цепей, находящихся под напряжением. Перед установкой и техническим обслуживанием отсоедините цепи питания и управления.

Compiled in this manual is a comprehensive set of documentation for your purchase. Please note that all equipment shall be installed in accordance with the edition of NFPA 70 National Electric Code along with applicable local codes. See the appropriate Outline drawing for recommended conduit locations. Allow for input and output power wiring to be located in separate conduit. No conduit holes are provided in the enclosure except knockouts for Type-1 Enclosures; therefore the customer must install all conduit holes.
Locate terminals T1, T2, and T3 in the panels and use these terminals to connect the motor wires. Depending on actual panel configuration, motor cables should be terminated on the load side lugs provided with the core Softstater non-bypass panel , Power Distribution blocks AC1 Bypass panel and Overload relay AC3 Bypass contactor configurations.
All field signal wiring must be twisted and shielded. All shields must be grounded at one point ONLY. Avoid routing signal wiring with power wiring. If signal wiring is routed with control wiring a minimum separation of one 1 inch is required.
Operator Devices page 3 2. Customer Terminal Board page 5 3. Adjustments page 8 5. Operator Devices Your Bypass and Non-Bypass panel is equipped with several panel door mounted operator devices, which may include the following: one 1 through-the-door, lockable, input device disconnect handle; two 2 operator selector switches; two 2 push buttons; three 3 meters; one 1 door mounted keypad and three 3 indicator lights.
Based on the selection, these components may or may not present in the panel. The operations of these devices are explained in this section. It should be noted that this will not cause AC input power to be removed from the Soft Starter. An open circuit between these positions will cause the Soft Starter to drop out resulting in power being removed from the motor.
These positions come jumpered together from the factory and require removal of the factory jumpers prior to connecting customer normally closed contacts. These contacts are utilized to energize an interposing relay for Starter control logic and to energize Isolation and Bypass Contactors via higher rated normally open contacts than those inherent to the Soft Starter.
Adjustments The Solid State RVSS panel has several user settable adjustments, which allow it to be tailored specifically for your 3-phase induction motor. Setting these adjustments appropriately is an important factor in ensuring that applicable safety codes are met and that your panel, wiring, and motor are adequately protected. Make sure there is not an unintended additional loading on the motor resulting in the excessive current.
Try another OL relay. Perhaps the tolerances on the one included with your panel are unfavorable. If the overload relay dial is set correctly but tripping occurs on across-the-line starts this is probably due to a large load inertia which results in high starting current being applied for a longer time to accelerate the motor from a stopped to full speed condition. These instructions do not purport to cover all details or variations in equipment nor to provide for every possible contingency to be met in connection with the installation, operation, or maintenance.
Refer to Electric Schematic and Outline drawing, which are included with the unit, for wiring and mounting details.
