DEVR40 Electric Vehicle Contactor Fig. 3 Overall Dimensions Optional auxillary switch wires White, 2 x 22AWG Ø 1.2 mm +ve Coil Wire Red, 22AWG Ø 2.4 mm -ve Coil Wire Black, 22AWG Ø 2.4 mm Stainless Steel Mounting Hardware (not supplied) 2 x M5 Bolt 2 x M5 Lockwasher 2 x M5 Narrow Washer Torque: 15 to 30IN-LB (1.7 to 3NM) A1 +VE Terminal A2 -VE Terminal All dimensions are in mm Notes: 1) Spring Washers for the power terminals are an essential requirement for installation. 2) Torque setting for the M8 Power Terminals is 8.8 to 11Nm. Exceeding the maximum torque may lead to product failure. 3) Loose terminals will generate excessive heat leading to premature failure and risk of fire. 4) The maximum torque setting for the M5 mounting bolts (not supplied) is 1.7 to 3.3Nm. to avoid damage to the contactor body. 6) For polarity conscious versions, please ensure the correct polarity of the wiring to the power terminals. Contact life is greatly reduced if the power terminals are incorrectly connected. 7) The contactor coil terminals are polarized. Please ensure they are connected the correctly. This contactor has an Energy Optimizer control PCB with an integral surge absorption circuit. external diodes are unneccessary and may degrade performance. The Energy Optimizer actuates approximately 0.1s after power is applied to the coil terminals, do not repeat on/ off or switch off during this time as damge to the contactor may occur. the available coil drive circuit power must exceed the contactor coil power requirements. 8) Ensure adequate circuit protection in case of contact malfunction. 9) The contact chamber contains an inert gas. For maximum life, do not exceed the ambient temperature range of -40 to +85°C. 10) Contact ratings are based upon a resistive load. For inductive loads an inrush protection device is recommended. 11) Avoid installing in a strong magnetic field (motor, transformer, external magnet etc.) and protect from heat radiation from nearby objects. The contactor coil performance changes with temperature (like all relays and contactors), this might occur from selfheating or from an external source, and it will affect the pull-in (operate) performance.
