EXCEL 500/600 INSTALLATION INSTRUCTIONS
Line Power Supply
WARNING
A separate CRT 6 or 1450 series (U.S.) transformer must be
used for each of the EXCEL 500/600 controller's 24 V supply.
No additional loads may be connected !
Each additional XL500/600 controller requires its own
transformer.
An additional transformer, appropriate to the power require-
ments, should be used to power input/output peripherals (e.g.
actuators).

To avoid interference, the cable between the transformer and
the power supply module should be kept as short as possible
(max. 6 ft (2m)). The transformer should therefore be
positioned close to the power supply module.
Fuse the transformer primary with its own fast-acting 10 A
back-up fuse (or H 16 or L 16 miniature circuit breaker).
The primary coil of the CRT 6 contains a 0.8 A / 250 V quick-
blow fuse.
Table 5 gives an overview of the transformers of the 1450
series (U.S.):

requirements.
XC6010 Computer Module
CAUTION
Do not unplug the computer module with the power
still connected, since this could destroy the module.
First, switch S1 on the power supply module to the 0
position.
If one of the C-bus submodules XD505A or XD508 is installed
on the XC6010, follow Fig. 47.
Fig. 47. Excel 600 CPU module C-Bus connections
The system bus is connected to terminal 16 (C+) and terminal
17 (C-). See also section "C-Bus Termination (Excel 600)" on
page 38.
If the XDM506 Modem Submodule is installed on the
XC6010, follow Fig. 48. Use the XW571 modem cable to
connect the appropriate modem to the wiring terminals.
