In the event of communication problems, the relay outputs
will move to the safety positions you have configured in
CARE, see relay output point description in the CARE –
User Guide, EN2B-0182GE51 / 74-5587.
WARNING
Risk of electric shock or equipment damage!
Low voltage and line voltage must not
be wired within
the same relay block.
► Wire low voltage e.g., to relay block 1 and line voltage to
relay block 2 or vice versa. In this case, the short cross
connectors must be used, see Table 5 on page 7.
NOTICE
Risk of malfunction!
Cross connectors may only be used if the same voltage
is used on all relays they connect.
► Do not use a cross connector if different voltages are
used on the relays.
E.g., use a short cross connector for relay block 1 with
line voltage and no cross connector for relay block 2 with
12 V low voltage for relay 4 and 24 V low voltage for
relays 5 and 6.
