3. Recommended Monitoring Devices
B&R recommends using PNOZ e1.1p or PNOZ e2.1p safety relays from the Pilz company
(
www.pilz.com ) in order to achieve Safety Category 4 in accordance with EN 954-1. As a
monitoring device for the E-stop button, the PNOZ e1.1p can be used for safety circuits up to
Safety Category 4 according to EN 954-1. It is imperative to use the PNOZ e2.1p as a monitoring
device for the enable switch for safety circuits up to Category 4 (EN 954-1).
Caution!
Pressing several function or system keys at the same time may trigger unintended
actions.
Information:
• Protective coverings on the device, housing screws, and damage to the
housing and cables should all be checked periodically.
• For instructions on cleaning the Mobile Panel device, see "Cleaning", on
page 135.

Warning!
If EN 954-1 Safety Categories 2, 3, and 4 are not necessary, safeguards can be
switched directly on the E-stop circuit for Categories B and 1. When doing so, be
aware of EN 954-1 and EN ISO 13849-2 guidelines as well as the max. permitted
current load on the E-stop button and the key switch! More information can be found
in the section 3.3 "Current Load of the Enable Switch and Entry Device Circuit" on
Page 92.
