Arc fault
protection ZŁ-4A; (07.2019)
Fig. 11
ZŁ-4A elements connection (with terminal).
Cable diameter should be adjusted to the length of the cable which connects the ele-
ments of the arc protection (see Table 1). For the cable length lesser than 100 m the diame-
ter of a single conductor should be not less than 0.5 mm2 (screened cable type LIYCY-P
2x2x0.5 mm2 is recommended). While for the cable length greater than 100 m the conductor
diameter should be not less than 1 mm2 LIYCY-P 2x2x1 mm2 recommended.
Connection of units to CAN bus:
•
CAN L clamps (A9 for JP/JW, B1 for JC) with CAN L line
•
CAN H clamps (A8 for JP/JW, B2 for JC) with CAN H line
In case of the last unit in a chain the terminator should be activated by closing contacts CAN
RL, CAN RH, CAN R (A5, A6, A7 for JP, B3, B4, B5 for JC). Connections diagram of several
ZŁ-4A devices is presented in figures Fig. 14, Fig. 15 and Fig. 16. The cable screen should
be connected to the PE clamp in the place of the JC installation. In other places the screen
should be terminated as close as possible to the JP/JW and then insulated.
