Information for Customers
› The ambient temperature range shall not overstep the temperatures given in the chapter Technical Data - Explosion proof solenoid (page 1).
The maximum temperature of the medium (generally hydraulic uid) shall not exceed 70 °C (158 °F).
› It is the users duty to ensure free and unhindered heat emission during operation. This means that the solenoid shall neither be covered not stored
immediately adjecent to heat sources (e.g. fan heaters) during operation.
› Care is to be given that the solenoid is not subjected to direct sunlight during operation.
Initial installation
› Installing the type VDC for temperature class T4 a cable with an ambient operating temperature of at least +105 °C (+221°F) is to be used.
For T5 and T6 a cable with an ambient operating temperature of a least +90 °C (+194°F) is sufcient. The fastening torque on the cable
gland depends of the used cable and is to be determined by installing user.
› When installing the VDC solenoid type, please note the fastening torque of the screws (4 Nm or 2.95 Lbf.ft)
and of the Connection box (0,4 Nm or 0.30 Lbf.ft).
› When installing the VDC solenoid type, an appropriate cable shoe M3 - 0,75 mm2
( with an ambient operating temperature of at least +105 °C or +221°F) is to be used.
› The user has to safeguard each solenoid with a fuse: IN ≤ 3xIG, with tigger characteristic “slow blow”.
The breaking capacity of the fuse link has to be stronger than the max short circuit current at the users operating area.
› EX-secured components must be used during mounting in case the fuse and/or the interface are within the EX-range.
› In addition, the solenoid may be connected to ground via the purpose-built ground clamp an the connector casing.
Installation notice - installation, mounting, demounting
› In case the solenoid shows any signs of a defect, malfunctioning or external damage (including corrosion), the device must
immediately be taken out of operation.
› Any deposits on the surface of the device shall not obstruct heat emission.
› To maintain legibility of the date plate, the solenoid must not be coated.
Safety notice - Please read carefully
› Always disconnect the solenoid from the power supply before any maintenance or other work on it.
› Always exchange the complete solenoid. Do not try to repair the solenoid.
› In no case shall any changes be made to the solenoid or the connecting cable.
› Demount the solenoid only in secure areas (not in EX-areas). If this is not possible, the solenoid must cool for 10 minutes minimum.
