For actuators with high nominal motor current (AUMA power class switchgear from
category A4), a control box is required. Switchgear (reversing contactors) will then
be installed in the control box and not within the actuator controls. The control box
is mounted separately on a wall.
Information on installation with control box
Cables and required number of wires are indicated in the wiring diagram.
The cable for motor connection has to be shielded.
For the power supply cable, fuses have to be provided for short-circuit protection
by the customer. The fuses have to be adapted to the cross section of the cable,
the thermal overload relay in the control box, the switch contacts and the motor
data (refer to motor name plate).
For wall-mounted actuator controls, additionally observe <Actuator controls on wall
bracket> chapter.
