Electro Cam PL-1746 Series - Manual (Page 19)

2-9 Installation
Overview
The PS-4108-13-L16 I/O rack provides inputs, analog outputs, and digital power outputs (requiring Slimline™ solid state
relays) for the PL-1746-C01 PLS plug-in modules. The rack is UL/C-UL listed. CE marking is pending.
PS The rack is a member of Electro Cam Corp.’s PL
µ
S product line.
41 The rack is mounted external to the Allen-Bradley module chassis.
08 The rack has 8 inputs.
13 The rack and PLS module communicate via Electro Cam Corp.’s proprietary Type 13 communications.
L The rack has two SLIMLINE analog output module slots. The rack is mounted on either EN 50035 G Profile
or EN 50022 Top Hat Profile DIN rail.
16 The rack has 16 SLIMLINE solid state relays.

CE Installations
For installations that must comply with CE requirements the PL-1746-C01 and PS-4108 must be mounted inside a
metal enclosure. In addition, a CoreCom 20VK6 or equivalent single stage PI filter must be connected across the AC
input to the SLC power supply. A Steward 28A2025-0A0 or equivalent ferrite bead must be snapped onto the resolver
cable as close to the enclosure wall (inside) as possible.
Installations must comply with all other manufacturer's requirements.
Mounting & Grounding
The rack’s mounting channel is held to either EN 50035 G profile or EN 50035 top hat profile DIN rail via three mount-
ing clips. The rack has a 4-40 captive nut connected to the ground plane that must be tied to earth ground in the
customer’s installation. This must be done to maintain EMC and electrical safety.
Cabling
The primary communications connector on the rack is connected to the PLS module via the special rack cable. The
secondary communications connector allows the user to daisy-chain a second rack to the first. These connections
provide both for receiving input power from the PLS and for communication with the PLS. The aggregate length of all
rack cables attached to a given PLS module must be 50 feet or less. The cable’s shield is tied to the metal jacket
covering the connectors on both ends. The jackscrews of the second DB9 are tied to ground on the PCB, while those
of the first DB9 are not. Thus the shield of each cable is tied to ground at only one end.
Power
The input voltage delivered to the PS-4108 rack from the PL-1746-C01 PLS module is nominally 24V (20V min, 30V
max) at a maximum of 250mA.
Fusing
Power Input Fuse (F1)
1/4 A, 250 V, TR5-F (European Style)
Spare Output Module Fuse(F3) 4 A, 250 V, TR5-F (European Style)
Fuse Tester
The rack includes a green LED (D3) that lights when
a good fuse is installed in the fuse tester.
Communications
DIP switch S1 selects the rack’s physical address. Note that if only one rack is used it must be addressed as rack 0.
