Final Installation and Power Up

Final Installation

Step 1:

Install the Paradigm architectural control processor (P-ACP) in the appropriate

module slot.

Step 2:

Install the Paradigm station power module (P-SPM) in the module slot above the

Paradigm architectural control processor.

Step 3:

Install option modules if they are not installed. For an ERn4, you may install a

Paradigm dual repeater module (P-DREP), two blank modules, or a Paradigm

station repeater module (P-REP) in the top module slot of the enclosure with a

blank module below.

Step 4:

Install either the ERn blank option module or the redundant power supply (ERn-

RPS) in the lower option module slot.
a: If installing the redundant rack power supply (ERn-RPS) module in the option

module slot, be certain you have completed the installation requirements.

Step 5:

Install blank air flow (ERn-BM) modules in any unused module slot in the

enclosure to maintain the required convection cooling requirements.

Step 6:

For 230 VAC CE ERn enclosures, reinstall the module retention bar to the left

side of the ERn enclosure. This module retention bar is required to maintain CE

compliance.

N o t e :

The optional redundant power supply (ERn-RPS) is not supported in ERn4

enclosures at 230 VAC. Instead the ERn4 at 230 VAC is shipped from the factory

with a rack power supply installed in the top (normal) position and in the lower

option module slot as standard.
