Terminals on ACL Unit
1> Refer to the figure at the lower left corner of this figure 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 the terminals P and 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.
