Attention
To prevent ignition through electrostatic charge all electrically non-conductive connection
points must be by-passed with equipotential bonding, e.g. decoupled section frame, flexible
connections, vibration isolation. All metallic parts of the units must be included in the local
equipotential bonding measures. The unit must be earthed on the base frame in
accordance with current best practice (foundation electrode). For this purpose a bore hole
at the base frame or a rivet on the floor (for units without base frame) is provided for ATEX
units and marked with an earthing sticker. All connections must be secured against coming
loose.

For reasons of operating safety a suitable lightning conductor system must be provided in
accordance with local regulations (e.g. DIN VDE 0185).

When connecting heating and cooling water piping (inlet and outlet), care must be taken to
ensure that the inlet and outlet connections are not confused (counterflow principle with
water inlet and air outlet side).
Connection of the Heating and Cooling Water Piping – Example
1 – Inlet, 2 – Outlet, Arrow – Direction of Air
