Water Proof Packing
1. For waterproof mounting, waterproof packing must be installed on
the Controller. Waterproofing is not possible when group mounting
several Controllers. Waterproof packing is not necessary when
there is no need for the waterproofing function.
2. Insert the E5EC into the mounting hole in the panel.
3. Push the adapter from the terminals up to the panel, and
temporarily fasten the E5EC.
4. Tighten the two fastening screws on the adapter.
Alternately tighten the two screws little by little to maintain a
balance. Tighten the screws to a torque of 0.29 to 0.39 N•m.

Mounting the Terminal Cover

2
to 0.8231 mm ) twisted-pair cable.
• Use crimp terminals when wiring the terminals.
• Use the suitable wiring material and crimp tools for crimp terminals.
• Tighten the terminal screws to a torque of 0.43 to 0.58 N•m.
• Use the following types of crimp terminals for M3 screws.
