Control unit mounting location should be planned so that the machine's washing does not damage the unit.
A direct water jet towards the control units should be avoided, especially when using high pressure. Also, the use of any such solvent that causes damage to electronic devices should be avoided when handling the control units.
|
|
|
When cleaning the control unit, do not use highly alkaline / acidic substances, too hot water, or too heavy mechanical abrasion. |
|
|
In moist conditions, the unit must be mounted and oriented so that the connectors are not filled with water.
|
The mounting is done with 2 screws, for example M6 according to DIN 912
It is possible to use a spring washer under the screw head
Mounting must be done on to a conductive metal base. The control unit's aluminum housing must have a galvanic connection to the machine frame
The paint must be removed from the control unit under each screw head before mounting, to ensure a galvanic connection to the control unit frame. Also, remove the paint from the machine frame, where the control unit will be attached.
Reserve 10 cm installation space for the connector cables
Mounting position must be horizontal or vertical to allow water, etc. flowing away from connectors, see the figures below.
If a separate Epec shock protection cover is mounted, it is recommended to use fastening bolts delivered by Epec.
The following figure shows how the shock cover is mounted on top of the unit with screws (unit mounting screws have threads for unit cover screws):
A = Shock cover mounting screw
B = Shock cover
C = Stopper washer
D = Shock cover mounting screw
E = Control unit
F = Shock cover mounting bracket
G = Shock cover base knob
H = Wires are binded to the base knob with cable ties
If the unit is mounted upside down with a unit cover in wet conditions, it is recommended to drill a small hole on the cover to allow water flow away on the bottom of the cover. In the picture below, the red arrow points an example location of a leaking hole:
