RCD (Residual Current Device)
The product can cause a residual-current in the external protective earthling conductor.
Q.HOME CORE has a built-in RCMU (Residual Current Monitoring Unit), which protects residual-current under
continuous and sudden conditions. If the RCD must be applied in a particular area, 30 mA or higher Type B RCD
must be applied.
CAUTION
■
It is must be used Type B RCD for Q.HOME CORE.
■
(optionally available) Type A RCD can be optionally used for critical load only for the
following manufacturers.
1. NHP
2. CLIPSAL
■
However, when Type A RCD is used, a ground-side DC component leakage current
exceeding 6 mA may cause magnetization of the RCD with electromagnetic coil in
such cases. This may negatively affect the function of the protection device.
■
The use of Type A RCD other than the manufacturer listed above may not work
properly to cut off leakage current of Q.HOME CORE. It’s the responsibility of
the installer to ensure the RCD used adheres to local installation and regulation
requirements.
6.4 Grounding Q.HOME CORE
Q.SAVE and Q.VOLT must be connected to an additional ground on the enclosure.
■
PE bolt: M4
■
Torque for PE bolts: 1.2 to 1.9 N·m
