Spring Washers are an essential requirement for installation - see Page 4.
Torque setting for the M5 Power Terminals is 3.4 to 4.5Nm.
Loose terminals will generate excessive heat leading to premature failure and risk of fire.
The maximum torque setting for the M4 mounting bolts (not supplied) is 2.3Nm. to avoid damage to the contactor body.
Please ensure the correct polarity of the wiring to the power terminals. Contact life is greatly reduced if incorrectly connected.
Contact ratings are with #8 AWG wire.
Ensure adequate circuit protection in case of contact malfunction.
The contact chamber contains an inert gas. For maximum life, do not exceed the ambient temperature range of -40 to +85°C.
Contact ratings are based upon a resistive load. For inductive loads an inrush protection device is recommended.
