Features:
- Injected-power terminal: Rated at 250 VAC and 1 A for the terminal-power path.
- Automatic keying: The key position is set during initial CHARM installation.
- Conditional powered handling: Removal under system power requires two explicit no-energy conditions.
KL4502X1-LA1 identifies the fused injected-power terminal-block hardware used at a DeltaV CHARM position.
Automatic keying records the first installed CHARM type and makes a later type change dependent on releasing the locked keys.
Environmental and maintenance limits define the enclosure and service conditions without implying universal CHARM compatibility.

- Circuit ceiling: Select KL4502X1-LA1 only when the injected-power path remains within the documented 250 VAC, 1 A terminal rating.
- Ambient decision: The enclosure must keep the terminal block inside its -40°C to +70°C operating range.
- Moisture and contaminants: Non-condensing humidity and ISA G3 define the documented cabinet environment, not approval for harsher exposure.
- Mechanical qualification: Compare the installed CHARM position with the published shock and 2–150 Hz vibration profile before release.
- First installation: The terminal-block keys are set automatically when a CHARM is first installed.
- Locked position: The key setting is retained for the installed terminal position.
- Different CHARM type: Remove the terminal block before resetting the keys.
- Reset action: Release the keys from their locked position before installing the different type.
- Powered removal condition: No CHARM may be installed.
