Unpacking
Relay products require careful handling before installation on site. Examine
the delivered products to ensure that they have not been damaged during
transport.
If a product has been damaged, a claim should be made to the transport
contractor and the local representative of ABB should be promptly notified.
3.1.
Identifying the product
Compare the order number of the relay with the ordering information to
verify that you have received the right product.
You can find the order number on a label under the lower handle of the relay.
When checking the order number of the relay plug-in unit, be
careful not to lift the handle more than 25º (approx. 40 mm).
Lifting the handle any further detaches the plug-in unit from the
case.

Electrostatic discharge (ESD)
The relay products contain components that are sensitive to electrostatic
discharge. The electronic circuits are well protected by the enclosure: avoid
removing the plug-in unit and the human-machine interface (HMI)
unnecessarily.
