2-1 Installation & Wiring
General Mounting & Wiring
Controller
The controller body mounts on a DIN rail as shown in Figure 4.
Keypad/Display
Mount the keypad/display to a panel using the four studs on the back of the keyboard.
Enclosures are available from Electro Cam if an appropriate mounting location does
not exist.
DIP Switches
For convenience, set the DIP switches on the side of the controller and keypad to
their proper positions before mounting the units in a panel. See page 2-13 for DIP
switch information.
Environment
1. Allow space at both sides and the top of controller for terminal blocks to be un-
plugged.
2. Ambient temperature range is +32
°
to +130
°
F (0
°
to +55
°
C)
3. Locate the controller and keypad away from devices that generate electrical noise,
such as contactors and drives.
4. Use the keypad/display gasket provided to prevent contaminants from getting into
the cabinet.
Terminal Blocks
All terminal blocks can be unplugged from the controller. Each block is keyed so it
cannot be plugged into the wrong socket. All terminals are labelled on each block.
Wiring Guidelines
Follow normal wiring practices associated with the installation of electronic controls.
Some guidelines are:
1. Route input and output wiring away from high voltage, motor drive, and other high
level control signals.
2. Use shielded cables for encoder, input, transistor output, and communication cir-
cuits. Also shield module output circuits that are driving low current electronic input
circuits.
3. Ground shielded cables at the PS-6244 end only (except for encoder cable). Use
any of the screws on the controller back for grounding.
4. Use appropriate suppression devices where module outputs are directly driving in-
ductive loads.
Power Supply Wiring
Connect a 20 to 30 VDC power supply to TB8 (Fig. 5 or 6). Reversing the polarity will
blow the 1-1/4 amp power fuse. The controller will not be damaged, but you must cor-
rect the polarity and replace the fuse before the controller will operate.
To insure electrical noise immunity, connect a good electrical ground to the ground
terminal on the power supply terminal block.
Module Mounting
A phillips head screw holds each module in place. Individual modules can be removed
and installed without affecting the other modules on the unit
However, disconnect power to the controller before changing modules.
