The dc supplies from the PSU are fed to the power distribution PCB. The optional PSU monitor
board, which enables monitoring of the power supplies, is mounted on the power distribution PCB.
An E Stop loop, front cover interlock, rear cover interlock/interlock blanking plug and E Stop relay
are fitted to ensure motor power is removed if the printhead cover or rear cover is opened or the
machine is crash stopped by pressing an E Stop button.
A two handed safety relay, left jog button and right jog button are fitted to enable certain functions
to be performed with the printhead cover open.
The M37 power supply crate has mains power available; when access to the components of the
enclosure is required, observe the following warning:
