Installation
Preventing the Risk of Electric Shock
The P-603 actuator does not feature a separate protective earth connection, but must be installed
in a way that a risk of electric shock is prevented.
You have the following options:
Mount the actuator onto an electrically conductive surface that is connected to a
protective earth conductor.
Connect the actuator to a protective earth conductor via its mounting interface.
Install the actuator such that it is electrically insulated according to protection class II.
When you choose the first or the second option:
1.
Pay attention to the applicable standards for mounting the protective earth conductor.
2.
Make sure that the contact resistance is
<0.1 Ω at 25 A
at all connection points relevant
for mounting the protective earth conductor.
3.
Install touch protection (e.g., housing, insulation) to prevent direct or indirect contact
with live parts.
Preparing a P-603 with Stranded Wires for Connection to a
Controller
When you prepare a P-603 actuator with stranded wires for connection to a controller, pay
attention to the assignment of the stranded wires as specified in “Color coding of stranded wires”
(p. 21).
