Safety information

Safety Information

This chapter provides very important information so that you can use the SDS Open Chassis Star-Delta Starter
safely, prevent injury or death, or damage to equipment. Please read this information thoroughly and make
sure you observe all the safety information shown below and elsewhere in this manual. Please make this User
Guide available for the end user.

Safety symbols

• The SDS Open Chassis Star-Delta Starter should ONLY be installed, commissioned and maintained by
qualified and competent personnel.

• The OC SDS must be installed to the latest IEE wiring regulations taking into account local
regulations.

• Dangerous voltages are present when the input power supply is connected to the OC SDS. Before
attempting any work on the OC SDS or motor, isolate and lock off the input power supply. Prove
dead using a voltage tester. The voltage tester itself should be proved immediately before and after
testing using a proving unit with a low power output.

• The OC SDS backplate must be connected to system ground using the earth terminals. The size of
the earth conductor and earth loop impedance must comply with national and local electrical
regulations.

• The SDS is a non-field repairable unit. Contact the supplier of the SDS.

• The mains supply and control supply to the OC SDS must be protected by suitable rated

fuses/MCBs.

• All machinery, in which this OC SDS is used, within the European Union, must comply with directive
98/37/EC, Safety of Machinery.

• Do not install the OC SDS in an explosive environment.

• The motor must be used within the manufacturers guidelines.

• Do not allow conductive material to enter the components within the OC SDS, e.g. from drilling

during installation.

NOTE: The thermal overload setting is set to minimum as default. It should be adjusted to suit the motor
used.

To calculate the thermal overload setting = Actual motor nameplate current ÷ 1.7 x 1.1 (10% safety margin to
prevent spurious tripping).

NOTE: Due to the large range of the thermal overloads on the Trip Class 20 star delta starters, please make
sure the thermal overload is adjusted correctly to suit the motor.

NOTE: Starting the motor more than once every 10 minutes will alter the thermal overload tripping
characteristic by heating the current sensing elements, making the overload trip more quickly for a given
setting.

NOTE: The above dimensions are only approximate and do not take into account the size of the thermal
overload on the trip class 20 star delta starters.

NOTE: The contactor sets between the Trip Class 10 and Trip Class 20 open chassis star delta starter may differ
hence the physical size of the trip class 20 may be larger than the equivalent trip class 10 model.

NOTE: The open chassis star delta starters are supplied pre-wired on a back plate. The starting and stopping
method will need wiring into the star delta starter. See Control Connections & Operation section of this User
Guide for example connections.

NOTE: The thermal overload is fitted into the output of the main contactor on the Trip Class 10 product. The
Trip Class 20 thermal overload is supplied as a separate module which will need to be mounted separately
from the contactors and wired into the output of the main contactor.
