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.

Mounting & Installation

Recommended Distance

Connection Example

RM17T 00 / RM17UB310

RM17TG20 / RM22 / RM35TF30

1. A fuse. UL…Class CC ; IEC…gG
2. Warning : Do not connect 3 phase control relay to monitor output of Variable Speed Drive (VSD).
3. 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.
