On safety
UL/CSA applications:
If the product is used in accordance with UL 508 or CSA 22.2 no. 142, the following
additional conditions must be met:
To protect the 24 V voltage supply to the device use a fuse with max. 4 A and min.
30 V DC in accordance with UL 248.
For the wiring, use only copper wire with a temperature resistance of at least
60 °C/75 °C (140 °F/167 °F), wire cross-section AWG 30-12 for screw terminals or
AWG 24-16 for spring terminals.
The screw terminal tightening torque must be 5 to 7
lb⋅in.
Use the devices only in an environment with degree of contamination 2 as a maximum.
The safety functions are not assessed by UL. Approval corresponds to UL 508, general
use.

Environmental protection
The EFI gateway has been designed to minimise environmental impact. It uses only a
minimum of power and natural resources.
At work, always act in an environmentally responsible manner.
Disposal
Disposal of unusable or irreparable devices should always occur in accordance with the
applicable country-specific waste-disposal regulations (e.g. European Waste Code
16
02
14).
Before you can turn over the devices for environmentally friendly recycling, you must
separate the different materials of the EFI gateway from one another.
Separate the housing from the remaining components (especially the PCB).
Send the separated components to the corresponding recycling centres (see Tab. 1).
