Caution: mounting ems55 series ems controllers vertically may result in water ingress as the IP rating of IPX5 applies only if
mounted horizontally, in addition, in correct installation may result in the following conditions:
l
if mounted vertically with the motion sensor close to floor, the motion sensor not be able to detect motion effectively.
l
if mounted vertically with parameter programming port close to the floor, any water ingress may occur.
l
if mounted too close the floor, water ingress may occur at the mains or line voltage terminals.
Cable routing to the ems controller is critical as water can trace or follow the cable downwards.
Therefore, immediately prior to the connection to the controller, a drip-loop must be formed in all wiring as shown below.
Attention:
l
Cable routing looms must not be secured to hot pipes or vibrating components.
l
Secure cable routing looms with clips where ever possible.

how to mount ems55 series controllers
ems55 series controllers have an IP (ingress protection) rating of IPX5.
An appropriate level of protection must be given for the effects of water ingress due to condensation, product spillage, and
so on.
Caution:The ems55 series controllers must not be exposed to temperatures greater than 55°C (131°F) or lower than 0°C
(32°F).
ems55 series controllers are designed for panel mounting and are secured using four countersunk self-tapping screws. The
aperture and screw pitch dimensions are shown below.
