WCL488 The “IEEE-488” Connector (RS232 Optional)
This is used for computer control and uses a standard IEEE-488 cable (refer to Figure 10).
WCL488 AC Input
This connection provides the Dynaload with its operating power and its safety ground (refer to
Figure 11). Power requirements are user selectable and described below in Table E.

110V
103.5 Vac – 126.5Vac at 1.5A
220V
187 Vac – 242Vac at 0.8A
NOTE: The operational frequency range is 47Hz – 63Hz.
Figure 11 WCL488. AC Input, Fuse and Input Voltage Selector
WCL488 Input Voltage Selector
The Input Voltage Selector (refer to Figure 11) is mounted on the rear panel immediately above
the AC input and fuse assembly.
WARNING:
Ensure that the power cord is removed before making changes to the
voltage selector tab.
WCL488 Fuse Replacement
Referring to Figure 11, the AC input fuse is located above the AC Input and below the Input
Voltage Selector. The fuse replacement part numbers for the Dynaload are MDA-3 (3 Amp, 250
