Relevant for North America:
The torque for tightening the supply voltage terminal block on the device is
4.5 lb-in (0.51 Nm).
The terminal blocks for devices with power unit characteristic value M or L
are coded to prevent them from being accidentally connected to devices with
power unit characteristic value L or M, respectively.
