2-10 Installation and Preparation PLZ-4W
2.8 Load Wiring
To ensure that the functions of the PLZ-4W work accurately and reliably, all wires
must be connected correctly to their loads.
• This operation manual refers to the terminal on the rear panel to which the equip-
ment under test is connected and current is supplied as load input terminal.
2.8.1 Precautions Concerning Wiring
Electric wire used
• Use a load wire with sufficient diameter for the current as well as non-flam-
mable or flame-resistant cover.
If the resistance of the load wire is large, a large voltage drop may occur when a cur-
rent is supplied and the voltage at the load input terminal may fall below the minimum
operating voltage. Refer to Table 2-1 and select thick wires as much as possible.
