AC Power
The 2-610 uses a standard, detachable IEC power cable.
Internal Voltage Selector
The 2-610 can operate at 115V or 230V. To change the mode, wait 5 minutes after power down, unplug
the AC power cord from the rear chassis. Remove the top cover. As shown below, there is a connector
that can be plugged in to one location or another location to configure the unit for 115V or 230V
operation. This figure shows the unit configured for 230V operation. The connector can be identified by
it’s wire colors; Black, Blue, White, Orange. This connector should be plugged into location H8 for 230V
operation and location H6 for 115V operation. The connector is part of the wiring that comes from the
power transformer located at rear center of the 2-610. When changing operating voltage, fuse value
must be changed as well. Make sure the 2-610 is properly set for the voltage in your area before
applying AC power to the unit! Failure to do so may damage the unit.

Fuse/Mains/Bulbs
The AC power fuse is located in the AC power connector block. Remove the power cord before checking
or changing the fuse.
A 400 mA time delay (slow blow) fuse is required for operation at 115 V.
A 200 mA time delay (slow blow) fuse is required for operation at 230 V.
A 6.3 V bulb (1847) is used for the power indicator light.
