4 Mounting
Install the device vertically to ensure proper heat dissipation (ventilation slots above and below).
The following values should not be exceeded when installing with the front panel at the top or
bottom:
• Output power:
50 % (787-1202 / 787-1212 / 787-1216)
40 % (787-1226)
• Ambient temperature:
55 °C
Other mounting positions should only be used at one‘s own risk!
Avoid electrostatic discharge!
The devices are equipped with electronic components that you may destroy by
electrostatic discharge when you touch. Please observe the safety precautions against
electrostatic discharge in accordance with DIN EN 61340-5-1/-3
.
Pay attention while
handling the devices to good grounding of the environment (persons, job and packing).

Figure 2: Removal
4.1.1 DIN-Rail Mounting
Install the device in accordance to EN 60715 by snapping it onto DIN-rail without tools (see figure 1):
1. Place the device with its DIN-rail guide on the top edge of the DIN-rail.
2. Press the device onto the DIN-rail [1] while simultaneously pulling on the latch (i) [2] until it
locks into place.
3. To ensure secure fastening on the DIN-rail, fit end clips on either side of the device (with a
block arrangement: on either side of the devices).
4.1.2 Removal from DIN-Rail
1. To remove (see figure 2) pull down the latch (i) [1] using a screwdriver or operating tool.
2. Tilt the device forward [2] and unhook it from the DIN rail.
4.2 Screw Mounting
The position and dimensions for the fastening clips are listed in the drilling template supplied with the
device.
1. Fit one fastening clip into each corresponding top and bottom snap-fit opening on the housing
(see figure 3).
2. Push down the fastening clip until it locks into place with an audible click.
3. Gently shake the fastening clip to verify that it is fitted securely.

5 Wiring
Make sure that the
picoMAX
®
Female Connectors are mated properly!
Mismating the input female connector (b) into the output connector (c) may lead to a
hazardous voltage of 230 V on the output side.
Make sure that the female connector is properly mated!
Do not insert a tool into the ventilation slots!
Components inside the device may be damaged if the blade of an operating tool enters
the ventilation slots. This may lead to serious damage with a risk of injury caused by
malfunction, overheating or electric shock!
When using a screwdriver or an actuation tool, ensure correct positioning between the
locking latch and the female connector!
The following conductors can be inserted directly without tools:
• fine-stranded conductors with insulated ferrule, all cross sections
• fine-stranded conductors with uninsulated ferrule, cross section > 0.5 mm²/AWG 22
• solid conductors, cross section > 0.25 mm²/AWG 24
