Attaching and Removing the Terminal Cover
Unscrew the two attachment screws in the upper part of the 30-CH Scanner Box and
remove the cover as shown in the diagram below. After connecting all of the input signal
wires to the input terminals, fasten the input signal wire with the cable clamp, re-attach
the terminal cover, and tighten the terminal cover attachment screws. Use crimp-on lugs
to ensure the connection to the input terminal is secure, and if it’s not necessary to use
the cable clamp, you can remove the clamp to widen the opening, and allow thicker
wiring. When connecting to all input terminals, the maximum allowable cross-sectional
area per cable (due to the restriction on the area of the cover opening) is the following.
With a cable clamp: 2 mm

, without a cable clamp: 19 mm
