The rear panel of the 402 Dilutor-Dispenser houses:

- sector block containing the power socket, fuse drawer and ON/OFF switch,

- keypad connector, - probe connector, - GSIOC connector.

Sector Block

The sector block contains the power socket, fuse holder and ON/OFF switch. Your 402 can be connected to a 100-120 VAC or a 220-240 VAC supply. In either case, two 1A type “T” slow blow fuses must be installed (reference 6730104006).

Voltage Selector

The instrument has no physical voltage selector. The 402 Dilutor-Dispenser can be connected to 100 or 240 V. Power control is carried out electronically on the power supply board.

Installing the Fuses

For safety reasons, your 402 is delivered without

the fuses installed. You must install two 1A type

 

“T” slow blow fuses (reference 6730104006), as

 

follows:

 

1)

Disconnect the power lead from the instrument.

 

2)

Use a small screwdriver to pry open the fuse

3)

Pull the drawer gently towards you, to open the

 

 

fuse receptacle.

 

4)

Push the fuses into position.

 

5)

Push the fuse holder back into the sector block.

 

In the figure, the drawer containing the fuses is shown separated from the sector block. In fact the drawer hinges downwards; it is not advisable, nor necessary, to remove it completely from the block.
