Function, Pin Assignment, Properties
Requirements on the connection to the 24V supply:
●
Minimum cross section: 1 mm
●
Maximum allowed inductance: 100 µH (2 twisted single strands, 75 m
long)
●
Parallel line routing where possible
Depending on the power consumption of the devices and the current carrying
capacity of the connector X13, check via how many devices one line for 24V
supply can be looped through. You might possibly have to connect another
device directly to the 24V supply and then loop through the control voltage from
this device to other devices.
Lethal electric shock by live parts with more than 50 V!
Before working on live parts: De-energize installation and secure power switch
against unintentional or unauthorized re-energization.
Before accessing the device, wait at least 30 minutes after switching off the
supply voltages to allow discharging. To shorten the waiting time until voltage
has fallen below 50 V, you can use a discharging device (see chapter "Appen‐
dix").
Check whether voltage has fallen below 50 V before touching live parts!
Never operate the drive controller without touch guard or without DC bus con‐
nector. Only remove the touch guard, if you want to use the DC bus connector
at the drive controller. If you do not use the DC bus connector any longer, you
have to cover the DC bus connection with the supplied touch guard.
The DC bus connection connects
●
several HCS01.1E-W00xx-x-03 to each other
●
one drive controller to a DC bus capacitor unit (to backup the DC bus
voltage)
The DC bus connection has been provided with a touch guard at the factory.
To plug the DC bus connector, you have to remove the tough guard.
