Installation, Maintenance & Troubleshooting guide | Version 05

5.4: Installation

• Open the door by rotating the door lock anticlockwise.

• Mount the starter on a vertical wall/ plate free from vibrations with proper nuts and bolts.

Refer operating instruction for mounting dimensions.

• Remove the rubber grommets for the incoming and outgoing cable connections. (Refer Fig. 13)

• Connect incoming and outgoing cables as follows (Refer Fig. 13):

- Use proper cable glands to ensure dust prooﬁng. For conduit entry use packed washers.

- Select correct size of cables from Table 25

- Connect line and motor leads exactly as per wiring diagram pasted inside the cover of the starter.

- Terminate the incoming supply cables on terminal block TB1 & outgoing cables to motor on terminal block TB2,TB3

(Tightening torque -Refer table 25B)

NOTE: LMRA is set in Manual mode (Factory setting)

WLCA is set in Delivery mode (Factory setting)

- Connect the earthing conductor to terminals marked (earth) on the starter body with torque 1.2 to 1.6Nm.

The Starter is now ready for commissioning.

• Initially set the overload relay to 0.58 times the rated motor current.

• Set the timer dial to the nearest value of starting time available on motor nameplate

• If it is not available, then set the dial to approximately 6-8secs.

Installation, Maintenance & Troubleshooting guide | Version 05

•Overload relay setting:

- For closer protection set the overload relay to actual phase current as measured by an ammeter. In the absence of an

ammeter, use the procedure given below:

- Start the motor and let it run for 30 mins. Then gradually reduce the relay settings till it trips. Set the relay at a slightly higher

value than this setting. Overload relay characteristics shown in Fig. 6 can be used to estimate the average tripping time at

diﬀerent multiples of set current.

- Allow a reset time of approx. 4 min. before pressing the blue knob on the relay to reset it.

- Restart the motor after some time. If the relay does not trip then consider it to be properly set. If the relay trips, set at a little

higher value than before and recheck.

• Close the front door.

Commissioning :

For exact setting of timer and overload relay, follow the instruction given

below:

Before switching ON recheck all external connections.

• Star-Delta Timer setting for FASD:

- First Switch ON the Rocker switch.

- Start the motor by pressing the ‘ON’ button shown in Fig. 12

- Measure the time taken by the motor to nearly reach rated speed or

steady state current condition (indicated when the motor reaches a

steady hum).

- Stop the motor. Set the timer to this measured value by rotating the

dial shown in Fig. 13A.
