## Simple wiring using Push-In Plus terminal block 

## **Easy and reliable installation and maintenance** 

When the conventional model with terminals on the top and bottom of the unit is installed in a small control panel, it is difficult to secure sufficient space for wiring. The Push-In Plus terminal block on the front of the G9SE make installation easier and much quicker.

## Faster troubleshooting with status indicators 

The indicators of conventional safety relay units only indicate the operating status of the internal relays (K1/K2), and it is difficult to check the operation or connection of safety input devices. The new intuitive LED indicators of the G9SE show the operating status of safety inputs and outputs, enabling faster and more accurate troubleshooting when the equipment stops.

When the G9SE detects an error, such as input wiring, an indicator will blink to show where the error has occurred. This minimizes downtime to identify the cause when the equipment stops.

(3) Do not apply any excessive voltage or current to the input or output circuit the G9SE. Doing so may result in damage to the G9SE or cause a fire. (4) Incorrect wiring may lead to loss of safety function. Wire conductors correctly and verify the operation of G9SE before commissioning the system in which G9SE is incorporated. (5) Do not apply DC voltages exceeding the rated voltages, or AC voltages to G9SE. (6) Use SELV/PELV DC supply satisfying requirements below to prevent electric shock. - DC power supply with double or reinforced insulation, for example, according to IEC/EN60950 or EN50178 or a transformer according to IEC/EN61558. - DC supply satisfies the requirement for class 2 circuits stated in UL 508. (7) The lifetime of G9SE depends on the conditions of switching of its outputs. Be sure to conduct its test operation under actual operating conditions in advance and use it within appropriate switching cycles. Apply protection circuitry against back electromotive force in case connecting inductive loads to safety outputs. (8) Do not operate the G9SE with flammable or explosive gas. An arc with operation and the heat of relay will cause a fire or an explosion. (9) Do not drop G9SE to the ground or dismantle, repair, modify G9SE, otherwise an electric shock may occur or the G9SE may malfunction. It may lead to loss of its safety functions. (10) Use protective device (Fuse etc.) for short-circuit protection and ground fault protection, otherwise a fire may occur or the G9SE may malfunction. (11) Auxiliary monitoring outputs are NOT safety outputs. Do not use auxiliary outputs as any safety output. Such incorrect use causes loss of safety function of G9SE and its relevant system. (12) After installation of G9SE, qualified personnel shall confirm operations and maintenance. The qualified personnel shall be qualified and authorized to secure the safety on each phases of design, installation, running, maintenance and disposal of system. (13) A person in charge, who is familiar to the machine in which G9SE is to be installed, shall conduct and verify the installation. (14) Perform daily and 6-month inspections for the G9SE. Otherwise, the system may fail to work properly,resulting in serious injury. Turn OFF the signal to Safety input and make sure G9SE operates without fault by checking the state of the LED indicator in inspection. 

(15) Conformity to requirements of performance level is determined as an entire system. It is recommended to consult a certification body regarding assessment of conformity to the required safety level. 

- (16) OMRON shall not be responsible for conformity with any safety standards regarding to customer's entire system. 

(17) Dispose of the Units according to local ordinances as they apply.

When mounting multiple units close to each other, the rated current will be 3 A. Do not apply a current higher than 3 A. If the output current is 3 A or more, make sure that there is a minimum distance of 10mm each between all adjacent G9SE units. 

- (6) DIN rail mounting 

- (12) Start entire system after more than 2s have passed since applying supply voltage to G9SE. 

- (13) Set the time duration of OFF-delay (Type G9SE-221-T @ ) 

   1. Set the time duration of OFF-delay to an appropriate value that does not cause the loss of safety function of system. 

   2. Set both of the two O on the front and back, to the same value. When setting the de After setting, make sure G9SE operating time is correct. 

- (14) To determine safety distance to hazards, take into account the delay of Safety outputs caused by the following time: 

   1. Response time 

   2. Preset off-delay time and accuracy of off-delay time 

- (15) Before G9SE outputs become in ON-state, non-regular self-diagnosis for Safety output circuit may be executed. On this occasion, the operating noise of internal relays occurs. 

- (16) In the place subjected to strong vibration or shock, mount G9SE to a mounting surface with screws and the screw mounting attachment. 

   - Otherwise, G9SE may not function properly due to vibration or mechanical shocks out of the rated values caused by sympathetic vibration of G9SE and the mounting parts, and so on.
