WCS Input Voltage Selector
The Input Voltage Selector (refer to Figure 21) is mounted on the rear panel immediately above
the AC input and fuse assembly.
NOTE:
Each WCS (slave) Input Voltage Selector
MUST be set the same as the master WCL488.
WARNING:
Ensure that the power cord is removed before making changes to the
voltage selector tab.
