SECTION 3
CE Certification-related Guidelines
Installation of any Moore Industries’ products that carry the CE marking must adhere to the
guidelines in the Recommended Ground Wiring Practices section in order to meet the EN 61326
requirements set forth in the applicable EMC directive.
The Low Voltage Directive also applies to the AC powered units and/or when connecting any of
its output relay contacts to voltages greater than 50 vac. In order to comply with EN61010-1 (Low
Voltage Directive) all guidelines in this section must be followed.
Contact/Load Suppression
When the instrument relays are used to switch an inductive load such as an external relay coil,
contactor, solenoid, large voltage spikes may be created in nearby cable harnesses. When
excessive, these voltage spikes can disrupt the operation of all nearby electronics including this
product. Inductive loads should have suppression devices installed at the load (for external relays
this would be right across the relay coil itself). Usually this is a simple diode for dc circuits. AC
circuits routinely use an R-C snubber. Please follow the external load manufacturer instructions for
their recommended suppression kits
