2.0 Installation and Safety Recommendations
2.1 Safety Notice
Qualified or trained personnel only should install the machine.
Electrical rotating equipment can result in property damage, serious
injury, or death, when improperly installed. Equipment should be
installed in accordance with the local and safety standards for
construction and guide for selection, installation and use of electrical
motors and generators.
Suitable for use on a circuit capable of delivering not more than
5000Arms symmetrical amperes, 250VAC maximum per drive rating.
Electrical and/or mechanical alterations are permitted only when
power is removed.
Drives with the 24V option (C, D) can have power to connector X1
without any indication. The monitor illuminates only if 24V is switched
on.
2.2 Electrical Installation
The wiring, fusing and grounding must be in accordance to the
national electrical code and any local codes.
Use of motor thermo switch:
It is recommended to survey the status of this protective device in the
position control.
Since the leads can carry high voltage-spikes, isolation by means of a
relay should be installed.
The thermal sensor mounted inside the motor of the FFA- and FHA-C-
series actuators is not used in conjunction with the controllers
described herein. The motor is protected by an additional motor-I²t-
function running at the controller, by means of monitoring the motor
effective current. As a result the thermal sensor is not used in this
case!
Connect the PE of all systems to a central point. The diameter of the
cable-lead must be (10mm²) min.
The following chapter contains important information
regarding the
mechanical and electrical installation
as well Safety Notes .
It is strongly recommended to read and observe this
chapter carefully.
