3.2.3 Power supply TCON01
If no 24 V DC internal works connection is available, use the TCON01
power supply. The power supply is designed for mounting on standard
rails NS35 and is capable of supplying two Terracompact II TCO030 units.
3.3 Supply voltage
Depending on design, the units are intended for connection to 24 V direct
voltage or 115 V / 230 V alternating voltage. The supply voltage is shown
on the type plate. Subsequent changes cannot be made.
If a TCO30 or TCB030 is supplied wiht 24 V, make sure that the supply
(24 V) is ungrounded. If required, the negative connection can be con-
nected with PAL.
