Device protection

ƒ The power supply module may only be driven from balanced mains

supplies. Mains supplies with earthed phase are not permitted.

ƒ The power supply module contains electrostatic sensitive devices. The

personnel must be free of electrostatic charge prior to assembly and

service operations.

ƒ All pluggable connection terminals must only be connected or

disconnected when no voltage is applied!

ƒ The power terminals +UG, −UG and PE are not protected against polarity

reversal.

– When wiring, observe the polarity of the power terminals!

ƒ Observe the max. permissible mains voltage. Higher voltages will damage

the power supply module.
