3.4: 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. 8)
• Connect incoming and outgoing cables as follows (Refer Fig. 8):
- Use proper cable glands to ensure dust proofing. For conduit entry use packed washers.
- Select correct size of cables from Table 15
- 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,(Tightening torque -Refer table 15B)
NOTE: LMRA is set in Manual 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.
Commissioning :
Installation, Maintenance & Troubleshooting guide | Version 03
Operating Characteristics:
The given characteristics (Fig. 6) are average values of all ranges and sizes of bimetal relays and are mainly intended to indicate
the inverse time current characteristics & tripping times of the same. The tripping times shown are for relays starting from the cold
state. At operating temperatures (heated at rated current) these are reduced to about 25% of the value obtained from the
characteristics.
Caution
• During commissioning or maintenance always ensure that the main supply is disconnected by switching
off the main switch & Rocker switch.
• If the relay trips even when set at rated motor current the suitability of the starter/relay for the particular application
should be checked with the nearest Siemens office.
For exact setting of overload relay, follow the instruction given below:
Before switching ON recheck all external connections.
• 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.

Table: 15B Terminal torque values
Operation:
• Ensure the door is closed.
• Rotate the Latch away from OFF push button
• Switch On the rocker switch.
• Check the status of amber LED. Wait till amber LED is continuously ON then only proceed.
• Depending upon Selector switch knob position for phase selection, Indication of incoming power
supply voltage can be seen on Dual VA meter.
• For starting the motor, press Green push button marked ‘I’ (Fig. 7)
• Line current of R phase is indicated by Dual VA meter.
• Indication of Motor ON can be seen on starter door through green LED.
• For stopping the motor press Red push button marked ‘O’ (Fig. 7)
Reset Operation
– If the overload relay trips, Reset manually.
(Allow a reset time of approx. 4 min.)

3.8: Troubleshooting Guidelines in case
any fault is at load side
Thermal overload relay provide protection from:
a) overload condition at Motor
b) single phasing at load side
a) overload condition at Motor: check the suitable Motor current rating and adjust the overload relay setting
dial as per the requirement.
b) Single phasing at load side – Overload relay tripped as inbuilt feature to protect from single phase faults.
Check the single phasing condition at Motor side terminal TB2,TB3 to Motor.
For both conditions restart the Starter after proper reset time of approx. 4 min.
