Mains Operating Voltage
Check that the instrument operating voltage marked on the rear panel is suitable for the local supply.
Should it be necessary to change the operating voltage, proceed as follows:
1. Ensure that the instrument is disconnected from the AC supply.
2. Remove the plastic push-rivets at each side edge of the top cover. Use the blade of a small
screwdriver to first ease out the rivet head and then fully remove the rivet body. Remove the two
rear panel screws securing the top cover; slide the cover back and lift off.
3. Change the transformer connections following the diagrams:
4. Re-assemble in the reverse order. To comply with safety standard requirements the operating
voltage marked on the rear panel must be changed to clearly show the new voltage setting.
Fuse
The AC fuse is located in the fuse drawer in the lower part of the IEC inlet connector.
The correct fuse type is 20 x 5mm 250V HBC time-lag with the following rating:
Make sure that only fuses with the required current rating and of the specified type are used for
replacement. The use of makeshift fuses and the short-circuiting of fuse-holders are prohibited.
Mains Lead
Connect the instrument to the AC supply using the mains lead provided. Should a mains plug be
required for a different mains outlet socket, a suitably rated and approved mains lead set should be used
which is fitted with the required wall plug and an IEC60320 C13 connector for the instrument end. To
determine the minimum current rating of the lead-set for the intended AC supply, refer to the power rating
information on the equipment or in the Specification.
Any interruption of the mains earth conductor inside or outside the instrument will make the instrument
dangerous. Intentional interruption is prohibited.
Mounting
This instrument is suitable both for bench use and rack mounting. A rack kit for mounting in a 19" rack is
available from the Manufacturers or their overseas agents.
Ventilation
The power supply is cooled by an intelligent multi-speed fan which aids vertical convection. Take care
not to restrict the air inlets underneath or the vents on the top. When rack-mounted allow adequate
space above and below the instrument and/or use a fan tray for forced cooling.
