if load is less than 50 mA a resistor
must be installed across the load.
these relay contacts must be force
guided contacts.

WArning: Arc suppression devices
should only be installed across the
coils of the machine control relays.
never install Arc Suppression
devices directly across the control
output contacts of the BeamSafe.
An arc suppression device installed
accros the contacts may fail with a
short circuit and will result in an
unsafe condition.
