1.2 Safety directives
1.
The device executes a function diagnosis when the drive is switched on
or is in the switched on state. In addition, an authorized electrician or a
skilled worker who is well acquainted with the relevant standards can
conduct the “Motor overload protection” safety function test. For this
test, the drive must be operated withright or left rotation (forward or
reverse running), and the current flow in a conductor is interrupted
(e.g. by removing the fuse in the L1 or L3 phase). The EMS2 then
switches off the drive within 1.5 to 2 s. The LEDs for right or left rotation
go out, and the ERR-LED and the reply output are set and the confirma-
tion can be retrieved via the bus.
2.
The device is an associated item of equipment.
Do not install the device in potentially explosive areas. When installing
and operating associated equipment, the applicable safety directives
must be observed.
3.
When using devices with 230 V AC control, always use the same phase
for the control supply voltage and the control inputs.
4.
If you use the “Automatic RESET” mode, the drive is switched on again
after the cooling time has expired - if a control signal is still present.
The cooling time is 20 minutes. For applications in the Ex-protection
area, automatic restart is not permitted.
5.
For safety technical data, please refer to this document and certificates
(EC type examination certificate and other approvals if appropriate).
6.
Electronic motor starters are not allowed to operate with variable
frequency drives.
7.
For emergency stop applications, the machine must be prevented from
restarting automatically by a higher-level control system.
