2. Installation.
2.1 Requirements.
The time module shall be mounted by the qualified installer having appropriate (required and necessary for a
given country) permissions and qualifications for connecting (operating) low-voltage installations. The unit shall be
mounted in closed rooms, according to the environment class II, of the normal air humidity (RH=90% max. without
condensation) and the temperature within the range from -10°C to +40°C. The module shall be connected only to power
sources having galvanic (transformer) separation from the network supply.
The unit shall be mounted in a metal casing (a cubicle, a terminal device) and in order to fulfill LVD and EMC
requirements the rules for power-supply, encasing and shielding shall be observed according to application.
2.2 Installation procedure.
1. Install a casing (a cubicle etc.) and lead cables through cable penetrations.
2. Install the PC2 time module on mounting pins or assembly belt (the pins shall be installed before a casing or a cubicle
is mounted).
3. Supply DC voltage to +VDC, -VDC terminals retaining polarization.
4. Supply AC controlled voltage to AC1 terminal.
5. Connect the signal of AC decay, i.e. OC1 or OC2 (depending on purpose of application) to a signalling device (LED,
transmitter input, central input, indicator etc.).
6. Fix the signalling delay time of OC1 and OC2 outputs by means of Z1 and Z2 jumpers.
7. After the tests and operation control are performed, a casing (a cubicle etc.) shall be closed.
