RCD incompatibility
Connecting this device to a power supply protected by a residual-current device can result
in damage to property and minor personal injury.
This product can produce a DC current in the grounding conductor.
When using a Residual-Current Device (RCD) in cases where direct or indirect contact can
be made, only a Type-B RCD shall be permissible on the line side of this product. If this is
not possible, an alternative means of protection must be applied; for example isolation from
the environment through double or reinforced insulation, or isolation from the power supply
using a transformer.
Do not connect this device to a power supply that is protected by a Type-A residual-current
device.
Note
Encoder Power Supply option not shown; it mounts to the din rail beside DS1.
The auxiliary voltage for control is switched on with the disconnect, DS1. The encoder power
supply, EPS, is a 120V powered +15 VDC output that is used in CLVC applications and is
available as an option. GND1 is connected to GND2, located in the I/O section using a
flexible ground conductor; several points within the Control Tub are grounded to GND1.
