• Switches. These devices are rated for operating volt-ages up to 600 VAC, 50/60 Hz.

INSTALLATION

• FD frame devices are for use in individual enclosures, panel boards, switchboards or other approved equipment.
• The installation procedure consists of inspecting, attaching required accessories, mounting the device and connecting and torquing the line and load wire connectors.
• Mounting hardware and unmounted wire connectors (where required) are available as separate catalog items.
• Note: Trip unit and accessory installation should be completed before the device is mounted and connected. (See installation instructions supplied with trip unit and accessory before proceeding).
• Note: Motor circuit interrupters and molded case switches are supplied as complete devices only.
• Note: Molded case switches do not have a PUSH-TO-TRIP button.
  • Turn off and lock out all power before installing or servicing.
  • Make sure that the device is suitable for the installation by comparing nameplate ratings with system requirements. Inspect the device for completeness and check for any damage before mounting.
  • Device must be in “Tripped” or “OFF” position prior to mounting.

To mount the device perform the following steps:

1. For individual enclosures, panelboards and switch-boards manufactured by Siemens Energy & Automation, Inc., follow the instructions provided with this equipment.
2. For those applications where mounting is on a flat surface of the customers equipment, drill and tap mounting bolt holes according to the drilling plan in Fig. 2. For handle escutcheon cut out plans refer to Fig. 3.
3. If device contains internal accessories, make sure terminals can be connected when the circuit breaker is mounted.
4. Position device on mounting surface.
5. Install mounting screws and washers. Tighten hardware securely.
6. After mounting the device, line and load terminals and accessory terminals should be connected.
7. After the device is installed, check all mounting hardware for secureness. Check wire connectors for correct torque requirements. Torque values for line and load connectors are provided on the device name-plate.

MANUAL OPERATION
Manual operation of the device is controlled by the circuit breaker handle and the PUSH-TO-TRIP button. The device handle has three indicating positions, two of which are molded into the handle to indicate ON and OFF. The third position indicates a TRIP position and is between the ON and OFF positions. (See Fig. 4)

• Device Reset
  • After tripping, the device is reset by moving the device handle to the reset position and then moving the handle to the ON position.
• NOTE: In the event of a thermal trip, the circuit breaker cannot be reset until the thermal element cools.
• PUSH-TO-TRIP Button
  • The PUSH-TO-TRIP button checks the tripping function and is used to manually exercise the operating mechanism.
  • NOTE: Do not spray or allow any petroleum based chemicals, solvents or paints to contact the molded parts or nameplates.
