2.7 Load Wiring
To ensure that the functions of the PLZ-U work accurately and reliably, all wires
must be connected correctly to their loads.
2.7.1 Precautions Concerning Wiring
■
Electric wire used
• Use a load wire with suf fi cient diameter for the current as well as non- fl am-
mable or fl ame-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 mini-
mum operating voltage. Refer to Table 2-1 and select as thick wires as possible.
