Warning

Before switching on this instrument and before connecting any other cable, the protective earth terminals of this instrument must be connected to the protective ground conductor of the (mains) power cord. The mains plug shall only be inserted in a socket 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-450 rear panel, are used for replacement. The use of repaired fuses and the short-circuiting of 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.

Before starting, check that the ON/OFF switch on the ASMi-450 rear panel is set to OFF.

AC Power Connection

Skip this section if the ASMi-450 is powered from a DC source.

AC power should be supplied to the ASMi-450 through the 5 feet (1.5m) standard power cable terminated by a standard 3-prong plug.

First, connect the power cable to the connector on the ASMi-450 rear panel, and then to the mains outlet.

DC Power Connection

Skip this section if the ASMi-450 is powered from an AC source.

Connect the power cable to the DC power connector, and then connect the other end to the DC distribution panel. Pay attention to correct polarity.

The connection to the user's equipment is made to the rear panel connector marked DCE. The interface type installed in the ASMi-450 is indicated by the label located above the DCE connector (for example, figure 2-3.A shows a ASMi-450 rear panel with RS-530 interface).

V.35 Interface The V.35 interface has a 34-pin female connector, wired for direct connection to V.35 DTE interfaces.

X.21 Interface The X.21 interface has a 15-pin D-type female connector, wired for direct connection to X.21 DTE interfaces.

RS-530 Interface The RS-530 interface has a 25-pin D-type female connector wired for direct connection to RS-530/-RS-422/V.24 DTE interfaces.

V.36 Interface If the required interface is V.36/RS-449/422, connect
