4-2-4 Wiring instructions
(1) Use shielded or twisted cables for connection to the control
circuit terminals and run them away from the main and power
circuits ( including the 200V relay sequence circuit ).
(2) Use two or more parallel micro-signal contacts or twin contacts
to prevent a contact faults when using contact inputs since the
control circuit input signals are micro-currents.
(3) Do not apply a voltage to the contact input terminals of the
control circuit.
(4) Always apply a voltage to the alarm output terminals (RA, RB,
RC, MO1) via a relay coil, lamp, etc.
(5) It is recommended to use the cables of 0.75mm
2
gauge for
connection to the control circuit terminals.
(6) The wiring length should be 30m maximum.
