1> Refer to the lower left corner of Figure 4.7 indicating the terminals on the ACL unit. When the fan inside the ACL unit is
connected with an external power supply, do not fail to connect with the power supply designated by NEC Class 2 (Power
supply limited to 100VA and below, and 8A and below even in case of Error). Avoid the high voltage portion and the high
temperature portion of the ACL unit when wiring the fan inside the ACL unit.
2> The phases of the AC input power to the main supply terminals L
1
, L
2
and L
3
must be same as those of the control power
to the control power terminals L
1AUX
, L
2AUX
and L
3AUX
.
3> It is recommended to install the DC bus protection fuses on the both lines to terminals P an N to prevent ground fault, when
plural number of load equipment is connected to the 8720MC-RPS Regenerative Power Supply.
4> Turn on the switch SW7-1 on the Regulator Board without fail.
5> Because driving current of sequence input signals is 5mA and below, use a contact of which minimum applicable load is
5mA and below.
6> Use the ACL unit in maximum surrounding air temperature of 55 degree C (131 degree F) and below.
