Specifications

2.5 Vibration and Shock
The frequency converter has been tested according to the
procedure based on the following standards:
The frequency converter complies with requirements for
units mounted on the walls and floors of production
premises, as well as in panels bolted to walls or floors.
•
IEC/EN 60068-2-6: Vibration (sinusoidal) - 1970
•
IEC/EN 60068-2-64: Vibration, broad-band random
2.6 Safe Torque Off
2.6.1 Electrical Terminals
The frequency converter can perform the safety function
Safe Torque Off (As defined by draft CD IEC 61800-5-2) or
stop Category 0 (as defined in EN 60204-1).
It is designed and approved suitable for the requirements
of Safety Category 3 in EN 954-1. . Before integration and
use of safe torque off in an installation, perform a
thorough risk analysis on the installation to determine
whether the safe torque off functionality and safety
category are sufficient.
Typical reaction time for terminal 37 is <10 ms.
2.6.2 Safe Torque Off Installation
To carry out an installation of a Category 0 stop
(EN60204) in conformity with Safety Category 3
(EN954-1), follow these instructions:
1. Remove the bridge (jumper) between terminal 37
and 24 V DC. Cutting or breaking the jumper is
not sufficient. Remove it entirely to avoid short-
circuiting. See jumper in Illustration 2.1.
2. Connect terminal 37 to 24 V DC by a short-circuit
protected cable. The 24 V DC voltage supply
must be interruptible by an EN954-1 Category 3
circuit interrupt device. If the interrupt device and
the frequency converter are placed in the same
installation panel, use an unscreened cable
instead of a screened one.

Illustration 2.2 shows a stopping category 0 (EN 60204-1)
with safety Category 3 (EN 954-1). An opening door
contact causes the circuit interrupt. The illustration also
shows how to connect a non-safety related hardware
coast.
