4 Installation and maintenance

Installation

1. The installation of all ABB Jokab Safety switches must be in accordance with a risk assessment for the

individual application and in accordance with local wiring regulations and EN 60204-1. Installation must

only be carried out by competent personnel and in accordance with these instructions.

2. M4 mounting bolts must be used to fix the switches. Tightening torque for mounting bolts to ensure reliable

fixing is 4 Nm. Tightening torque for the lid screws, conduit entry plugs and cable glands must be 1,5 Nm to

ensure IP seal. Only use the correct size gland for the conduit entry and cable outside diameter.

3. Check operation of all switches and control circuits by activating the switch (Depress the red button) and

resetting each switch by twising the red button. Ensure each time that the switches latch off and require

manual resetting.

4. Wiring LED (Not on LineStrong1):

Black or Terminal 2 is 0VDC.

When 24VDC is applied to the Red wire or Terminal 1, the lamp will illuminate Red.

When 24VDC is applied to the Green wire or Terminal 3, the lamp will illuminate Green.

If the LED is fitted but is not used ensure the conductors remain coiled and fixed away

from the internal mechanism.

Warning! All the safety functions must be tested before starting up the system.

Maintenance

Every week: Check correct operation of all the control circuits and latching mechanism. Inspect for damage to the

Emergency stop or casing.

Every 6 months: Isolate power and remove cover. Check screw terminal tightness and check for signs of moisture

ingress.

Warning! The safety functions and the mechanics shall be tested regularly.

Warning! In case of breakdown or damage to the product, contact the nearest ABB Jokab Safety Service Office or

impairing the safety of the device which in turn could lead to serious injury to personnel.

Caution! ABB Jokab Safety will not accept responsibility for failure of the switch functions if the installation and

maintenance requirements shown in this sheet are not implemented. These requirements form part of the product

warranty.
