About the Assembly
Prepare the wires
The total wire size range for the RTBs is 22…14 AWG. The wire may be stranded or solid.
ATTENTION
This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II
applications (as defined in IEC 60664-1), at altitudes up to 2000 m (6562 ft) without derating.
This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR 11. Without appropriate
precautions, there may be difficulties with electromagnetic
compatibility in residential and other environments due to
conducted and radiated disturbances.
This equipment is supplied as open-type equipment. It must be mounted within an enclosure that is suitably designed
for those specific environmental conditions that will be
present and appropriately designed to prevent personal injury
resulting from accessibility to live parts. The enclosure must have suitable flame-retardant properties to prevent or
minimize the spread of flame, complying with a flame spread rating of 5VA, V2, V1, V0 (or equivalent) if non-metallic.
The interior of the enclosure must be accessible only by the use of a tool. Subsequent sections of this publication may
contain additional information regarding specific enclosure type ratings that are required to comply with certain product
safety certifications.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, for additional installation requirements,
Allen-Bradley publication
1770-4.1.
• NEMA Standards 250 and IEC 60529, as applicable, for explanations of the degrees of protection provided
by different types of enclosure.
ATTENTION
Do not use wire ferrules on wires connected to the terminals on the modules.
