WARNING GUIDELINES

WARNING : Risk of electric shock.

INSTALLATION GUIDELINES 1. To prevent the risk of electric shock, power supply to the
equipment must be kept OFF while doing the wiring
1. This equipment, being built-in-type, normally becomes a arrangement. Do not touch the terminals while power is
part of main control panel and in such case the terminals being supplied.
do not remain accessible to the end user after installation 2. To reduce electromagnetic interference, use wire with
and internal wiring. adequate rating and twists of the same of equal size shall
2. Do not allow pieces of metal, wire clippings, or fine metallic be made with shortest connection.
fillings from installation to enter the product or else it may
3. Cable used for connection to power source, must have a
lead to a safety hazard that may in turn endanger life or 2
cross section of 1mm or greater. These wires should have
cause electrical shock to the operator.
insulations capacity made of at least 1.5kV.
3. Circuit breaker or mains switch must be installed between
power source and supply terminal to facilitate power ‘ON’ or 4. A better anti-noise effect can be expected by using
‘OFF’ function. However this mains switch or circuit breaker standard power supply cable for the instrument.
must be installed at convenient place normally accessible to
the operator.
4. Use and store the instrument within the specified ambient
temperature and humidity ranges as mentioned in this
manual.

MECHANICAL INSTALLATION GUIDELINES

1. Prepare the panel cutout with proper dimensions as shown

above.
2. Fit the unit into the panel with the help of clamp given.
3. The equipment in its installed state must not come in close
proximity to any heating source, caustic vapors, oils steam,
or other unwanted process byproducts.
4. Use the specified size of crimp terminal (M3.5 screws) to
wire the terminal block. Tightening the screws on the
terminal block using the tightening torque of the range of
0.5 N.m.
5. Do not connect anything to unused terminals.

Reset Mode:
1) If Reset Mode Selected is Manual, then the Fault
will Reset Manually by pressing the Reset key on
the instrument.
2) If Reset Mode Selected is Auto, then the Relay will
be reset after Selected Reset time once the healthy
condition achieved.
3) If Reset Mode Selected As ZVR (Zero Value Reset),then
the Relay will be reset after Selected Reset time once
the healthy condition achieved OR Zero Value reached.

Relay Fault:
1) If Relay fault selected is “off” than Relay will turn
“off” when fault is achieved, otherwise Relay will
remain turn “on”.

2) If Relay fault selected is “on” then Relay will turn

“on” when fault is achieved, otherwise Relay will
remain turn “off”.
