Safety Information
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
- Disconnect all power before servicing equipment.
- Confirm that the product power supply voltage and its tolerances are compatible with those of the network.
Failure to follow these instructions will result in death or serious injury.
WARNING
UNINTENDED EQUIPMENT OPERATION OR INADEQUATE OVERCURRENT PROTECTION
- Do not use in safety critical system.
- Do not disassemble, repair or modify the product.
- Install the product in the operating environment conditions described in this document.
- Install properly rated fuses as recommended in this document.
- Do not connect 3 phase control relay to monitor output of Variable Speed Drive (VSD).
- Ensure 3 phase input does not exceed the surge voltage limits stated in datasheet.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
Electrical equipment should be installed, operated, serviced, and maintained
only by qualified personnel. No responsibility is assumed by Schneider
Electric for any consequences arising out of the use of this material.

Connection Example
RM17T 00 / RM17UB310
RM17TG20 / RM22 / RM35TF30
- A fuse. UL…Class CC ; IEC…gG
- Warning : Do not connect 3 phase control relay to monitor output of Variable Speed Drive (VSD).
- Light indicator
Setting Example
Example 1: To set 3 phase voltage monitoring at 220VAC L-L +/-12 %, Asymmetry monitoring 5 %, Fault delay = 5 s using RM17TE00
Example 2: To set 3 phase voltage monitoring at 415VAC L-L, >U at 18 %, <U at 16 %, On delay = 5 s using RM22TR33
Example 3: To set 3 phase voltage monitoring at 220VAC L-N?>U at 18 %, <U at 16 %, >U Fault delay = 12 s?<U Fault delay = 9 s using RM35UB3N30
Setting Change & Reset
If the voltage range selection switch 1 position is changed while the device
is operating, all the LEDs will blink, but the product continues to operate
with the voltage selection preceding the change of position. The product has
to be powered off and on again for the new selection to take effect. All LED’s
return to their normal state if the switch is returned to the original
position.
