Precautions
Mount the Module
Follow these guidelines to mount the module:
• Modules can be mounted horizontally or vertically.
• Do not mount the module near any heat source that can increase the
operating temperature of the module.
• 1732ES modules meet IP65/IP67 (when marked).
• Mount catalog number 1791ES-IB16 and 1791ES-IB8XOBV4
modules in an enclosure rated IP54 (IEC60529) or higher.
ATTENTION:
To prevent electric shock, use a DC power supply that meets
these requirements:
• A DC power supply with double or reinforced insulation, for example,
according to IED/EN 60950 or EN 50178 or a transformer according to
IEC/EN 61558.
• A DC supply satisfies requirement for class 2 circuits or limited voltage/
current circuit stated in UL 508.
• Use an external power supply that is safety extra-low voltage (SELV) rated.
• Follow these precautions for safe use.
• Wire conductors correctly and verify operation of the module before placing
the system into operation. Incorrect wiring can lead to loss of safety
function.
• Do not apply DC voltages exceeding the rated voltages to the module.
• Apply properly specified voltages to the module inputs. Applying
inappropriate voltages causes the module to fail to perform its specified
function, which leads to loss of safety functions or damage to the module.
• Never use test outputs as safety outputs. Test outputs are not safety outputs.
• Note that after installation of the module, a safety administrator must
confirm the installation and conduct trial operation and maintenance.
• Do not disassemble, repair, or modify the module. This can result in loss of
safety functions.
• Use only appropriate components or devices complying with relevant safety
standards corresponding to the required safety category and safety integrity
level.
• Conformity to requirements of the safety category and safety integrity
level must be determined for the entire system.
• We recommend you consult a certification body regarding assessment of
conformity to the required safety integrity level or safety category.
• Note that you must confirm compliance with the applicable standards for
the entire system.
• Disconnect the module from the power supply before wiring. Devices
connected to the module can operate unexpectedly if wiring is performed
while power is supplied.
