Installation
3.1 Wiring Guidelines
To prevent electrical interference and to minimize start-up problems, adhere to the
following guidelines:
Use fully insulated and shielded cable for all signal wiring. The shield should be
connected to circuit common at one end only. The other end of the shield should be
clipped and insulated to prevent the possibility of accidental grounding.
Signal level wiring such as listed above should be routed separately from high level
power wiring (such as the A.C. line, motor, operator control, and relay control wiring).
When these two types of wire must cross, they should cross at right angles to each
other.
Any relay, contactor, starter, solenoid or other electro-mechanical device located in close
proximity to or on the same line supply as the DIV280-000 should have a transient
suppression device such as an MOV or R-C snubber connected in parallel with its coil.
The suppressor should have short leads and be connected as close to the coil as
possible.
