Device connection

Important information

DANGER

Hazard due to lack of effectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.

b

Ensure the safety relay is supplied with supply voltage in all operating statuses.

b

Ensure that the supply voltage of the safety relay is not connected via safety
sensors or safety switches in order to switch the enabling current paths.

DANGER

Hazard due to unexpected starting of the machine
Hazard due to electrical voltage

b

Make sure that the outputs of the safety relay have no effect on the machine
during mounting and electrical installation.

b

Make sure that the safety relay and the connected components are isolated from
all voltage sources during mounting and electrical installation of the device and
during mounting/dismantling of the front connector.

NOTICE

Enclosure rating IP20 only applies if the front connector is mounted.

Prerequisites

•

Electrical installation is done in conformity with IEC 60204-1.

•

The mounting rail is connected to the functional earth.

•

The voltage supply and connected signals meet the requirements for SELV/PELV
(EN 61140) or NEC Class 2 (UL 1310).

•

The external voltage supply must be capable of bridging a brief power failure of
20 ms as specified in IEC 60204-1. Suitable power supply units are available as
accessories from SICK.

•

The safety outputs and external device monitoring (EDM) must be wired within the
control cabinet.

•

When using the safety relay with voltages larger than the safety extra-low voltage:
The N/C contacts of the controlled contactors must be safely isolated from the
other contactor contacts.

•

Contact fuse with safety fuse gG or circuit breaker C: 6 A, maximum short-circuit
current I ≤ 400 A

•

The ground connection of all connected devices must have the same potential as
A2.
