2-8 Installation and Setup
Fuses
Make sure that only fuses with the required rated current and specified type, as
marked on the IPmux-1/1E rear panel, are used for replacement: 1.6A T 250V.
Whenever it is likely that the protection offered by fuses has been impaired, the
instrument must be made inoperative and secured to prevent any operation.
Connecting the AC Power
AC power is supplied to IPmux-1/1E through the 1.5m (5 ft) standard power cable
terminated by a standard 3-prong plug. The cable is supplied with the unit.
To connect AC power:
1. Verify that the AC outlet is grounded properly. Ensure that the supply voltage is
in the range 100 VAC to 240 VAC.
2. Check that the POWER switch on the rear panel is set to OFF.
3. Connect the power cable to the rear panel connector first and then to the
AC mains outlet.
Connecting the DC Power
To connect DC power:
• Refer to the DC power supply connection supplement.
Due to the high current capability of DC mains systems, care should be taken
when connecting the DC supply, in order to avoid short-circuits and fire
hazards.
DC units should be installed in a restricted access area, i.e., an area where
access is authorized only to qualified service and maintenance personnel.
Make sure that the DC supply is electrically isolated from any AC source, and
that the installation complies with the local codes.
The maximum permissible current capability of the branch distribution circuit
that supplies power to the product is 16A.
Before connecting the DC input plug, ensure that power is removed from the
DC circuit. Locate the circuit breaker of the panel board that services the
equipment, and switch it to the OFF position. When connecting the other end
of the DC cable, first connect the ground wire, then the position pole, and
lastly the negative pole. Switch the circuit breaker back to the ON position.
A readily accessible disconnect device that is suitably rated and approved
should be incorporated in the building installation.
