• The DC input terminals shall be supplied from a source providing electrical isolation
between the input and output, in order to meet the applicable safety requirements of
IEC 61010-1. For example, Class 2 or Limited Energy Source.
• All field wiring must have insulation suitable for rated voltages.
Unprotected cable ends
Risk of explosion through unprotected cable ends in hazardous areas.
• Protect unused cable ends in accordance with IEC/EN 60079-14.
Improper laying of shielded cables
