In addition, free from the problem of noise, use a covered metal cable duct or a steel protective
duct. The recommended minimum separation between the signal line and the power line in this
case is given in Table 2.3.
Table 2.3 Minimum recommended separation (when a covered or uncovered metal
duct is used)
Cable power

10 m or less 25 m or less 100 m or less
125 V or less, 10 A or less 10 or more 10 or more 50 or more
250 V or less, 50 A or less 10 or more 50 or more 150 or more
400 V or less, 100 A or less 50 or more 100 or more 200 or more
500 V or less, 200 A or less 100 or more 200 or more 250 or more
In excess of the above values 500 or more
(unit: mm)
Grounding
Ground the terminal block FG terminal and the input/output cable shield to the cabinet ground.
Ground the cabinet ground to earth 100 or less. Do not make a loop in the ground wire; ground
it using the shortest possible length of wire. Do not ground any other device to the MCS1000
ground.
