6. Mounting:
ATTENTION! : Consider the rotation direction of the actuator. The box is factory presetted to be installed parallel to CCW
rotating actuators (Normal acting). For installation on reverse acting actuator or perpendicular to the actuator, the cams inside
the box need to be reset before operating the system to avoid damages to the cams or to the sensors.
6.1 The box has on the bottom surface a drilling according to ISO 5211, as shown in the image. Fix the proper mounting bracket
(supplied in option by Eisenbau) to the box using M6 screws (6).
6.2 Move the actuator to a completely “Open” or “Close” position, then align the box shaft (3) to actuator slot (7) ensuring of their
correct coupling.
6.3 The box is designed, assembled and controlled to ensure a maximum operating torque, at the shaft, lower than 0,5Nm. An
excessive misalignment of the two shafts during coupling, may result in the increase of this torque value until reaching the
complete seizure of the shaft in the worst cases. Eccentricity between the two shafts must not exceed 0.2 mm.
6.4 The motion transmission from the actuator or valve to the box GD is attained by a mechanical coupling. Before installation on
a valve or an actuator, make sure that the orientation of the position indicator is correct.
6.5 Operate the actuator before making the electrical wiring to ensure proper alignment between box and actuator . If it should be
necessary, re-align box by loosening mounting bolts (6) and retighten bolts to the actuator (8) according to the required
direction of rotation when satisfied with alignment.
6.6 Replace the protective caps with suitably certified and temperature rated cable glands and blanking plugs permitted for use
with ATEX/IECEx flameproof enclosures.
7. Electrical Wiring:
caution ! : The electric components inside the box may carry dangerous voltage. The box must not electrically
connected during installation.
Follow switch adjustment, wiring instructions (if present) and indicator setting before servicing the limit switch box.
Make sure that the characteristics of the electrical connection are compatible with electrical parameters of operation of the Limit
switch box. Do not exceed the limit switch performance limitation. Exceeding the limitation may cause damage to the limit switch,
actuator and valve. Connect earth conductor.
attention ! : the minimum clearance required to remove the box cover is 60mm.
