Final Installation and Power Up 25
Step 3: Open the ERn door and check voltage between phase, neutral, and ground. The
ERn supports input power ranging + / - 10% of the rated voltage.
•
100 VAC, (acceptable range 90-110 VAC)
• 120 VAC, (acceptable range 108-132 VAC)
• 230 VAC CE, (acceptable range 207-253 VAC)
• 240 VAC, (acceptable range 216-264 VAC)
Step 4: Turn off power at the main circuit breaker.
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
either two blank modules, a Paradigm Dual Repeater Module (P-DREP) in the
top two module slots of the enclosure, or only a Paradigm Station Repeater
module (P-REP) in the top module slot with a blank module below.
Step 4: Install either the ERn blank option module, the ERn ethernet switch Module
(ERn-NET), or the Redundant Power Supply (ERn-RPS) in the lower option
module slot.
a: If installing the ERn ethernet switch Module (ERn-NET) or the Redundant
Rack Power Supply (ERn-RPS) module in the option module slot, be certain
you have completed the installation requirements. See “Install Rack Options”
on page 26.
Step 5: Install blank module (ERn-BM) in any unused module slot in the enclosure to
maintain the required convection cooling requirements.
N o t e : Neither the Redundant Power Supply (ERn-RPS) nor the Ethernet Switch module
(ERn-NET) are supported in an ERn4 enclosure at 230 VAC. Instead, an 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.
