2.1 Electrical Connections – Figs. 2.1 to 2.3
Warning. Before making any connections, ensure that the
power supply, any high voltage-operated control circuits
and high common mode voltages are switched off.
Note.
• Use flexible conduit for cable routing
(signal and power).
• Always route signal leads and power cables separately,
preferably in earthed metal conduit.
• Screened cable must be used for signal inputs and relay
connections. Connect the screen to the ground stud.
• The terminal blocks can be removed from the main p.c.b.
when making connections. Before removing any module
note its position – see Fig. 2.1.
Information. Use cable appropriate for the load currents.
The terminals accept cables up 12AWG for power supply
connections and 14AWG for all other connections.
