Installation - Start-up

Mounting the controller

Connecting to the DIN Rails

To connect the controller to DIN rails:

1. Use a flat blade screwdriver to attach the four fastening sliders to the extended position.

2. 

2. Attach the controller to the DIN fails.
3. Press the four fastening sliders to the retracted position.

The controller is connected tp the DIN rails using the fastening sliders.

NOTICE

Combination of DIN and fixed screws

A spacer must be added between the mounting surface and brackets if the controller is attached with screws in addition to the rail fasteners. The customer must provide the spacers since combining rails and fixed screws is not a standard solution.

Surface Mounting

To mount the controller to a surface:

1. Screw the controller at the four brackets (on the device corners) to the mounting surface.

Wiring

Follow these precautions prior to wiring:

DANGER

Turn off the AC motor drive power before doing any wiring. A charge with hazardous voltages may remain in the DC bus capacitors even after the power has been turned off for a short time. Measure the remaining voltage with a DC voltmeter on +1/DC+ and DC- before doing any wiring. For your safety, do not start wiring before the voltage drops to a safe level (less than 25 Vdc). Installing wiring with a residual voltage may cause personal injury, sparks and a short circuit.

Only qualified personnel familiar with AC motor drives are allowed to perform installation, wiring and commissioning. Ensure the power is turned off before wiring to prevent electric shock.

Ensure that power is only applied to the R/L1, S/L2, and T/L3 terminals. Failure to comply may result in damage to the equipment. The voltage and current must be in the range indicated on the nameplate (see the Climatix VFD User Guide, Nameplate Information for details).

All units must be grounded directly to a common ground terminal to prevent damage from a lightning strike or electric shock and reduce noise interference.

Tighten the screws of the main circuit terminals to prevent sparks caused by screws loosened due to vibration.

CAUTION

For your safety, choose wires that comply with local regulations when wiring.

Check the following items after finishing the wiring.

– Are all connections correct?

– Are there any loose wires?

– Are there any short circuits between the terminals or to ground?

1. Pull wiring harnesses from controller to each device and plug in according to diagram provided.

NOTICE

See the Climatix VFD Installation Instructions (A6V12282655) for the full installation instructions for the Climatix VFD.

The instructions below in this document will cover the basics on how to connect the Climatix VFD. See the Climatix VFD User Guide (A6V12384673) for additional information.

Connect the Climatix VFD to the Climatix RT Solution as follows:

1. Connect the VFD to Supply power [R/L1, S/L2, T/L3] using the recommended protected circuit.
2. Connect the motor to the VFD [U, V, W].
3. Connect to the controller using Modbus RS-485 [SGND, SG+, SG-] to your Climatix RT Controller [REF1, A1+, B1-].
4. To enable Safe Torque Off (STO) functionality, remove the STO Jumper [+24V, S1, S2] and install the STO equipment. See the Climatix VFD User Guide (A6V12384673) for additional information.

When using the Climatix RT Solution, connect I/O such as sensors and other devices directly to the Climatix controller to enable remote monitoring in the Climatix IC.
To connect I/O directly to the VFD or to utilize optional VFD accessories, see the Climatix VFD User Guide (A6V12384673) for additional instructions.
For an overview of Climatix VFD wiring, see the RTU Wiring Diagram. For a detailed drawing see the VFD Main Circuit and Control Wiring Diagram.
