4.4.4 Ballast Resistor Connection
♦ The size of the ballast resistor
should be agreed with the
manufacturer.
♦ Monitoring the ballast resistor by
means of a thermal protection
contact is recommended.
If no thermal protection contact is
used, input X5-3 must be bridged to
HIGH potential e.g. +15V X6-3.
