If you are integrating a 9/Series that has a final destination within Europe
you must attach a metal oxide varistor (MOV) to all connections that carry
AC power to the system.
If you have this control: then you need to connect a varistor to:
9/230, 9/260 or 9/290 the incoming AC connection on the power supply
9/440 the incoming AC connection on the ON/OFF module
The types of MOV that you need are:
AC Power Voltage Manufacturer Part Number
90-130 V AC Harris V130LA20B
130-265V AC V275LA40B
These devices are available through several vendors, including Newark
Electronics. They can be contacted at:
