AC LINE Receptacle: This connects the accessory power cord.
⑪
TIME LAG FUSE Holder: This holder contains a time lag fuse in a glass
tube. The amperage of the fuse must agree with the local AC line
voltage from which the unit is powered.
AC Line Voltage Fuse Amperage
100 V/120 V 0.4 A
220 V/240 V 0.2 A
⑫
LINE SELECTOR Switches: These two switches are to be set in
accordancewith the local AC line voltage (50 or 60 Hz) for the
instrument. For a proper setting, see 1.3 Setting LINE SELECTOR
Switches.
For line voltage change between 100 V/120 V and 220 V/
240 V, thepower fuse amperage must be also changed accordingly.
Note: When the AC line voltage for the unit is changed after
receipt of The shipping carton box of your super megohmmeter,
check the fuse amperage.
⑬
HV-EN (High Voltage Enable) Interlocking Connector: This connector is
provided for connection of an external interlocking switch on the
measuring jig designed to block the application of a high voltage
across the Rx
+/‑
measuring terminals for safety of the operator
when the switch is in the off position.
