Z-2400-A2 Series Wiring, Installation and Maintenance.
THE Z-2400-A2 NODES ARE TO BE INSTALLED AND SERVICED BY SERVICE PERSONNEL ONLY.
NO OPERATOR / USER SERVICEABLE PARTS.
BEFORE YOU BEGIN WIRING: Ensure that all programming is carried out BEFORE any wiring takes place!
All power and signals must be de-energised BEFORE connecting any wiring.
Z-2400-A2 Wiring & Installation.
Mounting:
* Also refer to Physical Layout (Page 6).
1)
Mount so the terminals are in a clean environment.
2)
Do not subject to vibration or excess temperature or humidity variations.
3)
Avoid mounting in cabinets with power control equipment.
4)
Allow 10mm minimum clearance between the Z-2400-A2 terminals and ANY conductive material.
Analogue Signal Wiring:
1)
All signal cables should be good quality overall screened INSTRUMENTATION CABLE with the screen earthed at
one end only.
2)
Signal cables should be laid a minimum distance of 300mm from any power cables.
3)
For 2 wire current loops, 2 wire voltage signals or 2 wire current signals, B5102ES is recommended. For 3 wire
transmitters and RTDs B5103ES is recommended.
4)
It is recommended that you do not ground analogue signals.
5)
It is recommended to use power supplies with ungrounded outputs.
6)
Lightning arrestors should be used when there is a danger from this source.
7)
Refer to diagrams for connection information.
Thermocouple Extension Wire:
1)
Use the correct thermocouple extension or compensation cable. i.e. Thermocouple type, insulation type, correct
colour coding.
2)
It is recommended to install extension or compensation cable in a grounded conduit by themselves, or use overall
screened cable with the screen earthed at one end only. Never run electrical wires in the same conduit.
3)
All wires that must be spliced should be soldered, or a proper thermocouple termination block used.
4)
Lightning arrestors should be used when there is a danger from this source.

Note 1. Because the Z-2400-A2O outputs are totally
Isolated, it is safe to use the same instrument quality
power supply on both channels as well as the power
supply for the device.
Note 2. All cables to be screened and the screens
earthed at one end only.
