ADDITIONAL EQUIPMENT
4.8.1
Remote Control Panel (RCP)
The remote Control Panel (RCP)
comprises a aluminum case and front
panel. It provides the same control
functions as the Control Panel on the
28V DC GPU. It is connected via a
cable between terminal strip X2 and
the protocol gateway terminal strip
X1, and can be installed as a wall-
mounted unit. The maximum distance
between converter and Remote
Control Panel is limited to 1200m.
The connection cable provided from
the customer must be screened and have paired stranded leads (0.4 to 0.6 mm
2
). The following
cables must be provided for the power (L+24V RCP, GND) and for data transmission:
Cable length < 100m:
for power supply, 2 pairs each for +24V and GND =
4 pairs
for data transmission =
1 pair
5 pairs
Cable length > 100m:
for power supply, 3 pairs each for +24V and GND =
6 pairs
for data transmission =
1 pair
7 pairs
Note: The power supply is provided via four or six pairs in order to minimize voltage drop on the
link cable.
The remote Control Panel is connected as follows:
•
Dismantle panel
•
Attach RCP to wall
•
Pass connecting cable
through cable gland in
housing
•
Connect cores to terminals
(as per circuit diagram
4.8.1.B)
•
Switch off converter (Q100)
•
Connect the connecting cable
to the protocol gateway A260
terminal strip X1.1 to 2 and
X1.5 to 6
