CAUTION
: While installing or servicing the power module, wear a grounding device and observe all electrostatic
discharge precautions. Failure to observe this caution could result in damage to, or failure of the power module.
Power Source Circuit Requirements
The IONPS-D-R1 power module must be connected to a Safety Extra Low Voltage (SELV) circuit. The installer
must first determine the circuit’s characteristics (limited current, and hazardous energy levels, etc.) and then
install the power module reliably, routing and securing the DC input wires safely in accordance with local and
national electrical codes.
Equipment Ground
WARNING
: The power module has a provision for grounding. Equipment grounding is vital to ensure safe
operation. The installer must ensure that the power module is properly grounded during and after installation.
Failure to observe this warning could result in an electric shock.
Disconnect Requirements
WARNING
: A readily accessible, suitable National Electrical Code (NEC) or local electrical code approved
disconnect device and branch-circuit protector must be part of the building's installed wiring to accommodate
permanently connected equipment. The approved disconnect device and branch-circuit protector must be
suitable for the rated voltage and current specified. Failure to observe this warning could result in an electric
shock, even death.
WARNING
: Ensure that the disconnect device for the external power source is OPEN (turned OFF) before
disconnecting or connecting the power leads to the power module. Failure to observe this warning could result
in an electric shock, even death.
CAUTION
: While installing or servicing the power module, wear a grounding device and observe all electrostatic
discharge precautions. Failure to observe this caution could result in damage to, or failure of the power module.
Connecting External Power
WARNING: Do not connect the power module to an external power source before installing it into the chassis.
Failure to observe this warning could result in an electrical shock, even death.
