Connecting the Power

The AC power is supplied to the ASMi-31 unit through the 1.5m (5 ft) standard power cable terminated in a standard 3-prong plug (see Figure 2- 2). The cable is provided with the unit.

The rated fuse for the unit is 250V / 0.1A slow-blow for 230V, or 250V / 0.2A slow-blow for 115V.

The unit has no power switch. Operation starts when the power is applied to the rear-panel POWER connector.

Warning Before switching on this instrument, the protective earth terminals of this instrument must be connected to the protective ground conductor of the power cord. The power plug shall only be inserted in a power outlet provided with a protective earth contact. The protective action must not be negated by use of an extension cord (power cable) without a protective conductor (grounding).

Make sure that only fuses with the required rated current, as marked on the ASMi-31 rear panel, are used for replacement. The use of repaired fuses and the short-circuiting of the fuse holders is forbidden.

Whenever it is likely that the protection offered by fuses has been impaired, the instrument must be made inoperative and be secured against any unintended operation.

➤To connect AC power to ASMi-31:

1.Connect the power cable to the connector on the ASMi-31 rear panel.

2.Connect the power cable to the mains outlet.

The unit will be turned on automatically upon connection to the mains.

➤To connect DC power to ASMi-31:

• Refer to DC Power Connection Supplement.
