Using screw terminals for 9163 connection:
¾
Secure the cables at least in pairs.
¾
Connect the 9163 separately from electromechanical power switchgear.
The 9163 and electromechanical power switchgear such as relays, contactors, solenoid valves
etc. must always be supplied from separate lines.
¾
Ground the equipment.
The following grounding conditions must be met:
o
voltage between neutral line and ground <1V
o
resistance <6 Ω .
¾
Use suitable line filters in the vicinity of high frequency generators or arc welding machines.
¾
Lay the mains-voltage cables separately from the signal lines.
If the power supply lead to the electronic instrumentation is subject to strong interference from switching
of thyristor controllers or motors:
¾
Provide the 9163 with a dedicated isolating transformer with grounded shielding.
If the mains voltage is subject to strong fluctuations:
¾
Install a voltage stabilizer.
