For the protection system, use MKKDSN series terminals from Phoenix Contact Ltd., and FKC
series terminals from the same company for the contact output line (D) (G), analog input line (E),
contact input line (F), serial communication line (H), analog output line (J), and explosionproof
status line (L) of the electronics section.
For the Ethernet line (L) (M), use twisted pair cables of CAT.5 or CAT.5E or multi-mode optical
fi ber of 50/125 μm or 62.5/125 μm.
For these wiring connections, use AI series crimp-on terminal from Phoenix Contact Ltd.
There are four types of crimp-on terminal for respective wire diameters (see Table 2.5).
Peel off the cover of wire by 6 mm for MKKDSN series terminals and 10 mm for FKC series
terminals (maker-recommended values).
CAUTION
• Parts such as the signal line, relay terminal, relay, and power supply to be connected to the
contact input/output shall comply with IEC1010 or CSA 1010.
• Connect wiring after securing protective grounding.
 External I/O cutoff output (power cutoff signal) (L)
Wiring for the cutoff signal must be performed in case the explosionproof requirements are not
satisfi ed.
The shield is grounded at the earth bar (see Figure 2.22). Remove the cover on the upper right of
the electronics section and perform wiring.
 Contact output for system alarm 1 (C) and contact output for
annunciator (D)
The wiring locations differ depending on whether the protection system is provided or not.
 Wiring to protection system A
Perform wiring to the terminals shown in Figure 2.19.
The MKKDSN series terminals from Phoenix Contact Ltd. are used.
For these wiring connections, use AI series crimp-on terminals from the same company. Check if
the crimp-on terminals meet wire diameters in Table 2.5.
 Wiring to the electronics section (without the protection system)
Perform wiring to the electronics section of the control unit (see Figure 2.22).
FKC series terminals from Phoenix Contact Ltd. are used.
For these wiring connections, use AI series crimp-on terminals from the same company. Check if
the crimp-on terminals meet wire diameters in Table 2.5.
