contaminants found in the application.
• In applications where fluids or moisture may be present,
seal the fitting threads with a product such as Teflon tape
or pipe dope.
Failure to comply with these instructions could result in
death or serious injury.

AWG) or solid wire (0,75 mm² - 1,5 mm², 18 AWG-16 AWG)
to desired connector terminals. Use 90 °C [194 °F] rated
wire when ambient temperature is to exceed 75 °C [158 °F]:
• Torque switch terminal screws to 0,8 N m to 1,0 N m
[7.1 in lb to 8.9 in lb]
