4.1 Mechanical Installation
The installation steps for the two versions are described in the following sections:
• Panel mounting unit, in Chapter 4.1.1 and
• Cabinet unit, in Chapter 4.1.2
4.1.1 Panel Mounting Unit
The connector sets are available as installation units for vertical installation in swit-
ching cabinets or control cases. They consist of:
• the heat sink with power semiconductor,
• the power component with main current connection,
• the control board (type VAE-2) and
• the potentiometer with rotary-type knob and scale (delivered loose).
DANGER! Prior to installation: before opening the switching cabinet or control
case, switch off the current supply, check that no voltages are present, and
protect against unintentional reconnection!
 Use the hole pattern to orient yourself, see Figure 4.1 on the following page.
 Fasten the unit to a vibration-free vertical support wall or installation plate in
the closeable switching cabinet (control location); hand-tighten the screws
and use only the intended holes.
 Install the supplied potentiometer for working stroke adjustment with scale,
rotary-type knob, pointer, and knob cover at a suitable location (e.g. switching
cabinet door or front of control case).
ATTENTION! Connector sets are temperature sensitive! Make certain that the
units are not installed near external beat sources, such as direct sunshine or
radiators. The ambient temperature must not exceed +50 °C during
operation!
4.1.2 Cabinet Unit
The connector sets are available in an enclosed cabinet(IP 54 in accordance
with EN 60529). The cabinet unit is suitable for mounting to vertical walls or
