ERn Wall-mount Installation Manual
Check Line Voltages
Check the voltage on your input terminals using a digital volt meter (DVM) before installing modules.
• HIGH LEAKAGE CURRENT
• Ground connection is essential before connecting supply
• Disconnect power before removing modules
• Service by qualified and authorized personnel only.
1:
Close the ERn door.
2:
Apply line power at the main circuit breaker for 90 seconds. Observe the enclosure for evidence
of shorting, like arcing sounds or a burning smell. If you detect evidence of shorting, shut off
power and fix the wiring.
3:
Open the ERn door and check voltage between phase, neutral, and ground. The ERn supports
input power r / - 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)
4:
Turn off power at the main circuit breaker.
Final Installation
1:
Install the P-ACP in the appropriate module slot.
2:
Install the P-SPM in the module slot above the P-ACP.
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
WARNING:
RISK OF ELECTRIC SHOCK! Working inside the enclosure with power applied
exposes you to the possibility of dangerous currents and voltages.
Line voltages will be on the input terminals during this procedure. You must
be a qualified electrician familiar with the hazards of working with high-
voltage electricity. Use extreme caution when performing this procedure.
