Wiring Requirements
All modules (whether main or Expansion) have four removable connectors
where the field wiring is made. They come in a choice of spring cage or screw
connection. Both types benefit from the following:
• Screwdriver axis parallel to conductor axis
• Positive connector retention (captive screws)
• Test connections for 1.2 mm (0.047 in.) diameter test pins or 1 mm
(0.039 in.) test plugs
The DYN module connectors are 16 way and the expansion module
connectors are 6 way. Each is keyed appropriate to location and module type.
Manufacturer technical data for these connectors is as follows.
WARNING: All wiring must comply with applicable electrical installation
requirements (for example, N.E.C. article 501-4(b)).
