288 Planning for installation
WARNING! If you operate the drive system with a safety module in
environmental conditions that are outside of the specified ranges for the safety
module, this can cause that a safety function is lost.
Electrical installation

General requirements
Electrical installation of the safety system must be performed according to the
practices outlined in chapter
Planning the electrical installation in the drive hardware
manual.
Chapter Installation checklists provides additional advice for the planning.
All wiring must be well protected, routed and clamped where practicable.
When installing cabling it must be assured that there is no pulling or pinching on the
cables.

Connections
Inputs and outputs
To design the safety system architecture and select components to be used, it is
essential to read and understand the different architecture options (for example single
channel / redundancy).
Single inputs can be connected to any terminal X113:1…4 or X114:1…4.
Redundant inputs must be connected so that one input is connected to X113:n, and
the other is connected to X114:n (n= 1…4; the same for both inputs).
Use diagnostic pulse TP1 (X113:10) for the X113 inputs and TP2 (X114:10) for the
X114 inputs.
