5.2.1.4.1 RECOVERY RESISTOR PROTECTION
In order to thermally protect the recovery resistor a set of parameters has been provided
in the menu. These parameters are:
• Resistor (RECOVERY RESIST. RESREC)
• Power (RECOVERY RESIST. POWER)
• And recovery coefficient (RECOVERY RESIST. COEFF)
The parameters to be set with the standard recovery resistors are shown in tab 5.1.

With 230 V
ac
mains power supply a more efficient series of recovery resistors can be used.
These optional resistors with the appropriate parameters are shown in tab 5.2.
