Rishabh Current Protection Relay Operating Manual And Installation Manual

Current Protection Relay Operating Manual and Installation guide
The Current Protection Relay protects system
from the current faults. Relay protects against
undercurrent, over current and unbalance
faults.
Multiple LEDs indicate type of fault that helps
for diagnosis purpose.
Switch (Key) is provided to enable/ disable
unbalance function and to select automatic /
manual resetting of faults upon fault recovery.
Manual reset ensures safety.
Potential free relay contacts can be used for
connection / disconnection of load or trigger
alarm for annunciation purpose.
relay configuration can be ordered in fail safe
and normal operation depending upon
application The application includes motor
protection, conveyor system and for process
industry, etc.

Installation:

Installation to be carried out by qualified person along
with life protecting equipment to prevent hazardous shock.
Isolate incoming supply before connection.
Do not expose device to Rain, Dust environment.
Keep at least 10-15 mm distance on both sides of device.
Do not install near Vibrating environment.
Do not install near Heat source.
Install Fuses of 2 Amp in series with supply.
Use Sealing provision to protect from unintentional
adjustment.

Mounting:

To mount the device it should be fastened to a standard 35mm DIN rail
(DIN50022).
To remove from DIN rail use screw driver to pullout clip as shown below.
Mounting On DIN rail

Connector details:

Input connectors are marked by numbers 1, 2, 3, 4, 5, 6 and potential free
relay contacts are marked as 11, 12, 14 for relay1 and 21, 22, 24 for
relay2.Rated switchgear and fusing is required to prevent inrush. Wire of
2 sq. mm with Lug is recommended for Input connection. Use suitable
screw driver so that sufficient force can be applied, excess force may
result in damage to inside circuitry. Control voltage is to be applied with
fusing to the connector numbered as 14, 24. Refer diagrams for input
connection.
