NOTE 3: Relay Outputs
The contact rating of all outputs is equal to 2A/240 Vac on resistive load.
• To avoid electrical shock, connect power line at the end of the wiring procedure.
• For power connections use No 16 AWG or larger wires rated for at least 75
°
C.
• Use copper conductors only.
NOTE 4: Power Line
Before connecting the instrument to the power line, make sure that the line voltage corresponds to
the description on the identification label.
To avoid electrical shock, connect power line at the end of the wiring procedure. For supply
connections use No. 16 AWG or larger wires rated for at least 75
°
C.
• Use copper conductors only.
• Don’t run input wires together with power cables.
• For 24 V DC the polarity need not be observed.
The power supply input is fuse protected by a sub miniature fuse rated T, 1A, 250 V. When the fuse
is damaged, it is advisable to verify the power supply circuit It is necessary to send back the
instrument to Dynisco for service.
