The electronic system has a built in diode for protection against connecting the DC power
with the wrong (reversed) polarity.
Also a fuse is present to protect the electronics against high current. The fuse used is:
800mAT, IEC 60127-2, 250 VAC, 300 VDC, Träge T UL:115V-300VDC
IMPORTANT!
Always use a fuse with the same specification as mentioned above
Figure 5-1: Power connection
DC power to the electronics is supplied through a dedicated power cable using one of the
cable entries of the converter housing (Figure 2-10: cable entries on the compartment to the
left).
IMPORTANT!
•
The power supply should be a NEC class 2 power supply (max 100VA, 24VDC, see
also IEC 61010-1, clause 6.3.1 and 6.3.2)
•
The protective conductor clamp terminal size M5, press-fitted in the terminal
compartment (near the main connection terminals), shall always to be connected to
the protective earth conductor of the mains supply. Conductors up to 4 mm² (11
AWG), wit a minimum of 1 mm² should be connected to this terminal.
•
The Protective Conductor clamp or GND of the connector can be used for cable
shielding.
5.3.2. Digital I/O connections.
The digital outputs are passive open collector outputs, galvanically isolated from each other
and from the main circuit. To use these outputs an external voltage source and current
limiting resistors must be applied.
NOTE!
IMPORTANT!
•
For normal operation a voltage up to 32 V may be used (exceeding this exception
wise up to 200 % will not harm) , the maximum current to be switched on or off is 100
mA.
