5. Initial Installation
› The ambient temperature range shall not exceed the temperatures given in chapter 2. The maximum temperature of the medium
(generally hydraulic fluid) shall not exceed 70 °C (158 °F).
› It is the user's duty to ensure free and unhindered heat emission during operation. This means that the solenoid shall neither be covered
nor stored immediately adjacent to heat sources (e.g. fan heaters) during operation.
› The solenoid shall not be subjected to direct sunlight during operation.
6. Installation - Installation, Mounting, Demounting
› Using the V DC type for temperature class T4 requires a cable with an operating temperature limit of at least +105 °C (221 °F), e.g. LAPP
FD Robust. T5 and T6 require a cable with an operating temperature limit of at least +90 °C (194 °F). The fastening torque on the cable
gland depends of the used cable and is to be determined by the installing user.
› When installing the V DC solenoid, the fastening torque of the screws shall be [4 Nm (2.95 lbf.ft)] and for the BARTEC connection box
[0.4 Nm (0.30 lbf.ft)].
› When installing the V DC solenoid, an appropriate cable shoe of size M3 with a crosssectional area of 0.75 mm
temperature limit of at least +105 °C (221 °F) is to be used.
› The user has to safeguard each solenoid with a fuse: I
Instructions - Table 2). The breaking capacity of the fuse link has to be stronger than the maximum short circuit current
at the user's operating area.
› EX-secured components must be used during mounting in case the fuse and/or the interface are within the EX-range.
› The solenoid may be connected to ground via the purpose-built ground clamp on the connector casing.
› The EX-solenoid shall only be operated with a valve body according to the instructions in chapter 12.
› The coil must not be activated alone – a connection to the valve body is required!
› The single parts needed for assembly are listed in chapter 13.
7. Specification
› Coils and plug cavity with watertight encapsulation. Temperature class of coil "F" [155 °C (311 °F)]
› Protection type IAW DIN VDE 0470, EN 60529 and/or IEC 529, device: IP 65
› Surface protection (casing) acc. DIN 50979 Fe//Zn8-12//Cn//T0
› Max. temperature of the operating medium (generally hydraulic fluid): 70 °C (158 °F)
› Max. ambient temperature: see chapter 2!
