9.3 Relay removal from case
The RER620 and RER615 models are designed
with a withdrawable case for easy replacement
and maintenance. However, it's important to note
that these IEDs are not meant for "hot swapping."
Before removing or installing the relay, please
carefully follow the steps provided below. You
can also find these instructions on a label located
inside the control cabinet's exterior door. Failure
to adhere to these steps may result in electrical
shock, causing serious personal injury, damage
to the unit and/or voiding of the warranty.
Removal:
1.
Turn the capacitor discharge switch clockwise
to activate the discharge position.
2.
Allow the capacitors to discharge for
approximately 2 minutes or until the capacitor
discharge LED (located on the ACM cabinet)
turns off. Avoid touching anything during
this time.
3.
Once the designated time has passed,
turn the screw that secures the IED handle
clockwise until it is fully screwed in, allowing
the handle to move freely.
4.
Lift the handle to a 90-degree angle with
the relay.
5.
Pull the relay straight out and place it on
a surface that is safe from electrostatic
discharge (ESD).
Installation:
1.
Confirm that the capacitor discharge switch
is still in the discharge position.
2.
With the relay handle at a 90-degree angle to
the relay, carefully slide the relay back into its
case, ensuring proper alignment during
reinstallation. Do not apply excessive force
when inserting the relay.
3.
Push the handle down, ensuring that the relay
securely locks back into the case.
4.
Turn the handle screw counter-clockwise until
the screw head is flush with the handle,
securely locking the handle in place.
5.
Turn the capacitor discharge switch counter-
clockwise to the charge position.
